30 seconds might be timing-out,
instead let the browser handle the sleeping:

<?php
$goto='http://tt.mot.com/to_pdf/pdf_tmp/test.pdf';
$sleepfor=30;

printf('<META HTTP-EQUIV="Refresh" CONTENT="%d URL=%s">',

That I know, calling fgets() 3 times would put the file pointer at the start of the 4th. line. However, fread() "won't let you decide the position from which the acquisition begins.." according to my help book. Perhaps the filepointer is in the right spot, perhaps not. fread() requires an fseak() file pointer to offset the start of the file to where you want to begin reading.

Ok.. I've got the source.. However, pulling the calendar out of php.net is a bit trickier than it seems.

I'm getting some results: http://pgs.ca/calendar/cal.php

But it certainly wasn't built to allow other folks to easily incorporate this calendar into their sites.

I suppose that they have had to conseal some things for the sake of security. However, it is proving to be a real nussance.. This has likely got all that I need for an event calendar.. However, I can't add events (big pain).

It is just a bloody nussance to untangle.

I think I now have the authorization figured out.. The trouble I think is in this line of code (and it's sister Reject_Selected which follows shortly after:

if(isset($HTTP_POST_VARS['Approve_Selected_x']) || isset($HTTP_POST_VARS['Approve_Selected']) || isset($HTTP_POST_VARS['Approve_Selected_y'])) { foreach($entries as $entry=>$val) { $result = mysql_query("update phpcal set approved=1, app_by='$user' where id=$entry"); if(!$result) echo mysql_error(); } }

This doesn't seem to be doing anything and I can not echo any results from: echo $HTTP_POST_VARS['Approve_Selected_y';

What the heck am I doing wrong here?

I've got one that I downloaded from freshmeat and adjusted to do more things that I was after.

You can find a sample of the output at:

http://calendar.outbackqld.net.au/lsc/

The source is available as a tar.gz if you click on the application copyright link in the footer of the pages.

I'm actually doing a re-write at the moment to add a more robust admin module but it's a while away from being released as I've got other more pressing projects on the go.

It would be useful if you would point out which error it is you are encountering.

my guess would be that you need a semicolon on the first line.

Hi All,

Another doubt. How can I delete files older than X seconds from a given folder?

At the on-line manual I could only find a contributed note about 'discover time of last modification' from a file under a folder.

Any help is appreciated.

<Reply>

I don't exactly see any problem here. If you want files older than X seconds, and you have a modification time... Then you can unlink() them can't you?! I think you pretty much found the solution yourself. But just in case... Take a look at the following manual pages and create a construction with them. I think these are all you need.

http://www.php.net/manual/en/function.opendir.php http://www.php.net/manual/en/function.readdir.php http://www.php.net/manual/en/function.closedir.php (in order to scan your directory)

http://www.php.net/manual/en/function.stat.php (in order to get the modification time)

Hope this helps... And if this wasn't the problem... Tell me/us!

That's because $fp is a file POINTER, not the actual contents of the file. You might have been thinking of the file() function, which sucks the entire contents of the file into an array...very wasteful, if all you need are the first few lines. What you want here is:

$fp = fopen("meh.txt","r"); for($i=0;$i<2;$i++) { print fread($fp, 4096); } or unset($FileArray); $fp = fopen("meh.txt","r"); for($i=0;$i<2;$i++) { $FileArray[] = fread($fp, 4096); }

foreach($FileArray as $line) { print $line; }

The second parameter in the fread function is the maximum line length; normally, that would be set to ma number larger than the maximum line length you're likely to encounter (unless you have long lines, and only need the first few characters of that line). See:

http://www.php.net/manual/en/function.fopen.php and http://www.php.net/manual/en/function.fread.php

Also, the line

print "$fp[$i]";

isn't likely to work the way you expect; if $fp was an array, you'd get something like

Array[0] Array[1] Array[2]

as the printout, since the $i, in quotes, wouldn't be interpreted as an array index. Use something like

print $fp[$i]; or print "Some text here ".$fp[$i]." more text here";

instead.

<Reply>

Take a look yourself... Pretty obvious isn't it?! There's some code missing! At least... well... It's not right. You either don't close your foreach() loop which starts at line 3, or you don't close the if() loop which starts at line 2, and you definitely don't close the if() loop which starts at line 1. You probably mean something like:

1 if (empty($DidSurvey[$p_surveyid])) { 2 if (is_array($p_answers)){ 3 foreach($p_answers as $value) { 4 $sql = "INSERT INTO RESULTS(SURVEY_ID, ANSWER_ID) VALUES(" . $p_surveyid . "," . $value . ");"; 5 mysql_query($sql); 6 } 7 } 8 } else { etc.

Manuel,

Thanx for the excellent overview of metabase. I will give it a test drive. A couple further questions, if you have time:

Do you execute meta commands like you do with the other db interface functions, e.g., odbc_connect(), odbc_select(), etc., or are you able to encapsulate SQL between tags, e.g.

<tag> SELECT bar FROM foo WHERE barname = "chocolate"; </tag>

Using a function set can be cumbersome, compared to embedded language interfaces where you just put SQL between tags, just like PHP is handled between the <? ?> tags.

Also, can you PREPARE, DECLARE, and OPEN cursors like, say, in Informix, so you can use variable SELECT parameters? For example, using Informix ESQL/C you can PREPARE a statement, use it to DECLARE a CURSOR, and the OPEN the CURSOR USING multiple values, as in:

sprintf( query, "%s %s %s %s %s %s %s %s %s", "begin work;", "update account set balance = balance + ?," "where acct_number = ?;", "update teller set balance = balance + ?", "where teller_number = ?;", "update brance set balance = balance + ?", "where branch_number = ?;" "insert into history values (?, ?);", "commit work;" ); $prepare qid from $query; $execute qid using $delta, $acct_number, $delta, $teller_number, $delta, $branch_number, $timestamp, $values;

I should be able to check metabase out later this evening. If it can handle the above native database language, I think it will be an asset, especially for some of our older applications.

Thanx again, James Potts

That is the subject of some other project that I have which is an actual meta-language defined in XML. You write what you want to do with XML tags, and there is a compiler that translates that in to code of a target language, like PHP. This is not yet a released project although I have given a talk on this in San Diego O'Reilly Open Source conference in July, and if all goes well I will give another talk in November in PHP conference in Frankfurt. More information on that is available here:

Metabase supports prepared queries which you can execute as many times as you want with different values, if it is that what you are asking.

I am not sure if it is exactly what you are asking. In any case there is an extensive manual and a tutorial that details all it can do.

How did you install PHP? I guess you are building from source. I'm not a postfix user, but I think you have configured PHP w/o sendmail warpper.

Install sendmail wrapper then build PHP again. (e.g. configure checks if your system have sendmail or not)

You don't have to be sorry. It is your point of view. You don't have to agree. I don't feel insulted. I don't take difference of points of view personally, if they are just that.

The problem is not PHP-GUI capabilities being able to compete with other languages. The problem is that you seem to be willing to omit them when you present PHP as if it is something you don't want PHP be known for.

My point to suggest that was to help you to make it work according to a criteria that you would accept. In the end it would to favor your cause, which is the PHP future. I can't justify any time spent on that because I don't depend on PHP for my professional future. Currently, I even do not even program for a living. I manage people in a company that pays me for managing software development projects.

In this company, they have choose Microsoft stuff because they think it is the right choice for what they do. For some things, PHP could be a better choice, but it would be hard to convince who is in charge above me because PHP does not benefit of a great credibility in the market that would help me to make a good case to switch to PHP. This is my most important point: to make PHP a credible well known solution in all markets that it could be used with advantage.

Manuel,

This thread is long since dead. Your points are respectfully taken by all of us, but I for one believe you are missing a fundamental point. That in mind, I've prepared a list of ubiquitous tools in use today. These tools are not backed by big marketing budgets or Microsoft or anything of the like. Some are represented in trade shows. Some don't say a word. Some have done crazy things like you have suggested we do, like contests. Some are old, some are relatively new. The only common thread they have is their success. Some went down a road similar to what you've suggested. Some have gone down long roads, some short. Many of the names you will see here today enjoy the backing of corporations who have built their existence around the survival (and thriving) of a technology which they did not create and do not own.

Apache Sendmail BIND Perl HTML/WWW Python Linux C++

I hope you will consider the point I'm making here and leave this thread to the winds. And for what it's worth, in passing, the reason PHP-GTK is not mentioned when presenting PHP is that it isn't relevant. You won't win hearts by dazzling them with irrelevant features. PHP-GTK is a great project, but the world is slowly being captivated by the power of its web capabilities, not buttons.

Microsoft chooses which sites it links from microsoft.com *very* carefully - a very small select number of sites gets connected to it, and usually only for specific purposes (e.g., a specific article). If you draw a comparison to the PHP world, you actually proved my point.

>The problem is not PHP-GUI capabilities being able to compete with other >languages. The problem is that you seem to be willing to omit them when >you present PHP as if it is something you don't want PHP be known for.

I actually mention PHP-GTK in my sessions. I mention it as an anecdote, much like I mention some of the other interesting modules and projects in PHP (e.g., PEAR). I'm really not sure why people think I'm trying to bury PHP-GTK. Just because I don't see PHP-GTK as a main course of PHP, doesn't mean I don't think it's an important and useful project.

In the US (and perhaps in the rest of America), that's relatively true. That's not the case in Europe or the far east. It has a lot to do with mentality and corporate culture.

Jordan,

Following (at the end of this post) is the code for a Unix daemon (daemon.c). It is setup to run on both System V and BSD. I am not familar with Linux. In any case, you link in the object built from this code with your main C program. After you've setup your environment in your main module, call daemon_start( 1 ). You do not need to start it as a background process, since it will fork itself and kill the child, anyway. The main thing the daemon does is disassociate itself from any terminals and ensures zombie processes are left in the environment.

Apart from starting the daemon, you'll need to setup an infinite loop in your main module. Here's a snippet from a main module we use to query a table, scg_system, that our applications in windows write to if they need to execute a report on our Unix database server: The only thing scg_system has is a varchar field for the reports command line, a status to tell if the command line has been run yet, and a time stamp. We use the status of 1 to tell if scg_sysd has read the row to execute the command line (so it won't execute it again); 2 to indicate that scg_sysd successfully executed the command; and 3 if scg_sysd tried, but could not execute the command, in which case the error is logged by the LogError() function.

A good way to test your daemon, is to just setup main(), call daemon_start(), and then in your infinite loop open a tty and write to it , then close the tty. After the wait() in your main() program, another child will be forked and it will write to the tty again. Once you're satisfied it works, just kill the process. Warning: Do not test a daemon on a production system. It is not difficult to code in an error that might cause the program to start forking until it fills-up the process table.

/* * check for an open database before continuing. This first loop is used because the daemon is started when the system * inits and the database will not yet be running. */ while( 1 ) {

if( !fork( ) ) { i = nCreateTable( ); /* nCreateTable() returns 0 when it has successfully checked for/created the table */ fprintf( fp, "%d", i ); /* write 1-char stat to tmp for parent */ fclose( fp ); exit( i ); } else {

wait( (int*)0 ); /* wait for child to exit */

if( ( fp = fopen( szTmpNam, "r" ) ) == NULL ) { LogError( "Can't open tmp file(2)", 0 ); exit( 1 ); }

fread( szBuf, sizeof( szBuf ), 256, fp ); /* get status */ fclose( fp ); /* close and unlink tmpfile */ unlink( szTmpNam );

status = atoi( szBuf ); if( !status ) break; /* the database is started; scg_system exists */

tmpnam( szTmpNam ); if( ( fp = fopen( szTmpNam, "w+" ) ) == NULL ) { LogError( "Can't open tmp file(3)", 0 ); exit( 1 ); } } } /* end while */

fclose( fp ); unlink( szTmpNam );

Try outputting the result direct to your browser, without anything in the way to define it as an image - that way you may get to see the error.

<Reply>

There's actually no good way to achieve it in a different way. You could include/require the new page, but that's actually what you don't want (<quote>Besides printing the page in the script itself</quote>). But there is a different way to do it. It concerns the frame-layout, though. 'Cause if you use frames, the URL of one of the frames will not be shown in the location bar. But then you'll have to use frames, which I don't know if you want. One thing I can tell you though... of a page that's being shown, you cannot hide the URL. Never.

Second of all, in some versions of MySQL numbering of table records for an offset on LIMIT starts at 0, newer versions at 1. I'm using the older version as you can see but you will want to check your Oracle documentation for future information.

<?php $perpage=10;

//you'll want to change the above to 9 since that is how many items per page you want to show.

$q = "SELECT COUNT(*) AS NumImage FROM Photo_Image WHERE Cat_ID = '$id' GROUP BY Cat_ID"; $db->query($q); $db->next_record(); $numrows = $db->f("NumImage");

if (empty($offset)) { $offset=0; //Again, offset may be 1 or it may be 0.. check docs. }

$q = "SELECT Photo_Image.*, Photo_Cat.Name FROM Photo_Image, Photo_Cat WHERE Photo_Image.Cat_ID = '$id' AND Photo_Cat.Cat_ID = '$id' ORDER BY SortOrder LIMIT $offset, $perpage"; $db->query($q);

// print stuff here

$pages = ceil($numrows/$perpage);

if ($offset - $perpage >= 0) { ?> <a href="<? echo $PHP_SELF; ?>?func=ph&id=<? echo $id; ?>&offset=<? echo $offset - $perpage; ?>">[Prev] </a><? }

if ($pages > 1) { for ($x = 0; $x < $pages; $x++) { ?> <a href="<? echo $PHP_SELF; ?>?func=ph&id=<? echo $id; ?>&offset=<? echo $x * $perpage; ?>"><? echo $x+1; ?></a> <?

} }

if (($offset + $perpage) < $numrows) { ?> <a href="<? echo $PHP_SELF; ?>?func=ph&id=<? echo $id; ?>&offset=<? echo $offset + $perpage; ?>">[Next] </a><? }

Hope this helps. Joel

Hello ! Why this script prints an empty string(it prints nothing) as the value of the variable "u" ? This happens even if $REQUEST_URI or PHP_SELF is used instead of SCRIPT_FILENAME . Thanks...

<? function menu( $theurl) { //global $u ; $u = $SCRIPT_FILENAME; echo $u; echo $theurl; } ?>

Hello there !!!

<? menu(hoho.com) ?>

attached mail follows:

you have to use $GLOBALS["SCRIPT_FILENAME"]

Variable scope.

You need a "global $SCRIPT_FILENAME;" at the top of the function.

Hello,

Here are 2 tables:

airport --------- airport_id name code city_id

destination ----------- destination_id dest_name airport_dep_id // using airport.airport_id (departure) airport_arr_id // using airport.airport_id has well (arrival)

I have 2 columns in the second table that uses the same name column in the first table...

I dont know how to formulate my SQL query... I want to select the destinations in the destination table with not the ID of each airport but their names. I can do a join with one but with the second one, I get no results... And this is confusing!

select dest.dest_name, air.name as airport1, air.name as airport2 from destination, airport air where dest.airport_dep_id_id=air.airport_id and dest.airport_arr_id=air.airport_id;

This is not good...

Any help?

Thanks!

Please try select dest.dest_name, air.name as airport1, air2.name as airport2 from destination, airport air, airport air2 where dest.airport_dep_id_id=air.airport_id and dest.airport_arr_id=air2.airport_id;

you can use the same table as manu times as you like in sql. It's calld a self join if my memory does not fail me. --- Web Manager <webinter-resa.com> wrote: > Hello, > > Here are 2 tables: > > airport > --------- > airport_id > name > code > city_id > > > destination > ----------- > destination_id > dest_name > airport_dep_id // using airport.airport_id (departure) > airport_arr_id // using airport.airport_id has well > (arrival) > > > I have 2 columns in the second table that uses the same > name column in > the first table... > > I dont know how to formulate my SQL query...

Hey all, I've been using php for a long time and never have I had a problem with fopen(). Everytime I try to use fopen, I get some weird error messages. If I do fopen("http://www.php.net", "r") - I get this error message: Undefined error: If I try doing fopen("http://www.somehost.com/~myname/somefile.php?var=value", "r") - I get this message: Bad file descriptor What the heck is going on here? I've tried everything, except for submitting a bug report. I hope someone will have some answers.

Thanks, Paul

Well, try it from the command line and strace it and see which errno the socket open call is giving you (you said you weren't a newbie).

You're trying to do operations on a file descripter that doesn't exist?

I'm sure http://www.php.net exists. :)

Any help debugging the below would help greatly :)

ok, I ran strace and tried this via a command line: bash-2.05$ strace ./tmp.php

A snippet from tmp.php looks like this:

##################################################### #!/usr/local/bin/php -q <?php

$fopen = fopen("http://www.php.net/", "r"); exit; #####################################################

This was the output from the strace.

No, what my sentence meant was you're trying to do some operations on a mis-typed file descripter?

$fp = fopen... fputs($fp2... ^- There should be no 2.

Possibly something like that?

we're trying to get a krb4 c-client working with php built as an apache server module (either dso or static).

we've hit a wall in that, c-client itself seems to have access to the environment in which apache was started, but not the apache environment.

ie... we threw this into c-client:

{ extern char **environ;

int i;

for ( i = 0; environ[ i ] != NULL; i++ ) { fprintf( stderr, "%s\n", environ[ i ] ); } }

and the environment that c-client itself can see is: [Fri Aug 31 00:22:19 2001] [info] Server built: Aug 30 2001 12:11:45 APACHE=/usr/local/httpsd/bin/httpsd AWK=/usr/bin/awk GREP=/usr/bin/grep HOME=/ KRBTKFILE=/ticket/p1090525904 PIDFILE=/usr/local/httpsd/log/httpd.pid PS=/usr/bin/ps PWD=/ USER=nobody

ie - the same stuff phpinfo() lists under HTTP_ENV_VARS. We really need access to the HTTP_SERVER_VARS (we're revising the krb4 imap patches for c-client, *really* need access to REMOTE_USER from within c-client itself).

does anyone have suggestions?

Dear all I'm trying to write a user input form which when the user click the submit button, two task of php will proceed.

2. The form will regenerate a new page which for the user to print out to get approveral, but is there any script for php that when the user click the submit button, the Regenerated page which print to user default printer automatically??

Pls help

Thx Jack jacknedcor.com

attached mail follows:

if there were, webmasters could take control over your printer using their website. what a horrible thought! you can start a "request for print" however, simply by adding :

document.print();

// --> </script>

this will open a print window...

I assume you're running PHP on a Linux box.. You should be able to restart apache.. even on NT you could stop and restart the service.

Hei all.

I've got this string, $string = "test"; and I want to make a $t; out of $string. Is this possible?

I tried ${substr($string, 0, 1)}, but that didn't work ;)

Any help appreciated.

TIA.

Hi, I'm using the following code: for ($i = 0; $i < 100; $i++) { $k = (int) microtime(); echo " $k";

for ($j = 0; $j < 10000; $j++) $m = $j *3; }

but it prints me only "0......"

Where can be problem ?

Thanks,

attached mail follows:

You are casting microtimes results as an integer value. It isn't an integer value, hence the 0.

From the manual It returns the string the string "msec sec" where sec is the current time measured in the number of seconds since the Unix Epoch (0:00:00 January 1, 1970 GMT), and msec is the microseconds part. This function is only available on operating systems that support the gettimeofday() system call.

Try:

for ($i = 0; $i < 100; $i++) { $k = microtime(); echo " $k";

for ($j = 0; $j < 10000; $j++) $m = $j *3; }

Or look in the http://www.php.net/manual/en/function.microtime.php for examples.

<?php $a="123 456"; echo (int)$a; $b=(int) $a; echo " "; echo $b; ?>

Produces : 123 123

So I don't think that the problem is how PHP makes the casting but the algorithm is useless. Do that : $ar=explode(' ',microtime()); $a=$ar[1]+$ar[0];

string microtime(void);

you see? you're casting from a string to int by your code: (int) microtime();

you can do: $k = microtime() w/o the (int)
