Thanks, Richard. I agree with you. Is date_format() a MySQL specific
funtion? If so, we're out of luck because our backend DB is MS Access.

If I'm understanding what you're asking, you have an array of checkboxes whose
values you want passed to you PHP via the $_POST array. The HTML form syntax
would be something like:
<input type="checkbox" name="array[]" value="..." />
<input type="checkbox" name="array[]" value="..." />
<input type="checkbox" name="array[]" value="..." />
etc.
Then in your PHP script, $_POST['array'] will hold an array of the checkbox
values.

Hi,
I would like to know if it exist a method to reload a PHP page via PHP code
?
the topic behind is that i do not want to specify the PHP page to reload.
It must reload the actual page only.
for example, if use views the page : test.php and click on US flag image.
PHP should reload this page with US language...but i do not want to write in
hardcoding the page name, because this function should be usefull for all
pages.
thanks a lot

Just how much time do people spend reading the manual?
There is a pre-defined variable called $_SERVER['PHP_SELF'] you may also
want to look at things like basepath etc.

Although the question is vague here I go.
I would use sessions to determine what language is displayed.
When the user clicks the flag then the php page it goes to sets a
language var in the session and redirects back to the original page that
the user was on.

i was wondering what is the most secure way to use mysql in php. is there a certain way it should be done or a way that is more secure than another?
iv'e seen it done many ways and was wondering if it was just preference or a if there was a reason behind it.

Display the different ways in which you've seen php using mysql, and we'll
see if any one of them is any more secure than another.
Most Security issues can be left to MySQL and the MySQL API.
A few pointers -
Store parameters(username/password) outside the DocuementRoot.
Put your server on local host - or create an ssh/ssl tunnel between the PHP
machine, and the DB.
Cast any numbers, and escape any strings. ( mysql_escape_string )
Configure mysql securely - this is outside the scope of an email.

Hi,
Like the subject says; I have two questions:
1) Is it possible to detect JavaScript via php... and yes I do know that JS
is client side while PHP is server...but how else to do it?
The reason I ask is before serving an AJAX page I would like to make sure JS
is enabled, if not, serve the other "normal page"... I am sure I am not the
first person to come accross this little problem, how did you solve it?
I have seen some suggestions on google like having a hidden form field and
using js to put a value in it, if it exists when the form is sent then JS
is on..if not, its not... but that method is not the best in an AJAX
situation...right?
2) How can I search in an array for a particular word?
eg: in an array "movie" I have this kind of data:
movie_name=> some movie
cast=> Jim Carrey, Richard Pryor, Eddie Murphy
I want to search on either "Richard" or "Richard Pryor" (must be case
insensitive too)
something like a SELECT with a LIKE %% statement
I have been fooling around with in_array() but not getting anywhere
fast..... am I on the right track?
Links, code examples or advise would be as always....appreciated.
Thanks,
Ryan

First question. Technically no, you can't detect js from php.
However, I read where one can detect if a user has cookies on by
sending a cookie and then reading it back. And considering that you
can send a cookie via js, you could do that. However, that would mean
that the user had to have both js and cookies on.
Second question. Unless I don't understand the problem, simply use a
loop and stristr().

It is probably a better to approach this backwards. So load the non JS
page, and within it detect if javascript is enabled, in which case
perform a javascript based redirect to the Ajax enabled page.

stripos() is a better candidate since you are only looking for the
string and it skips the extra processing of stristr().

Posted by Fred Mitchell on December 11 2004 2:47pm [Delete] [Edit]
Let's say you are doing a LEFT JOIN with a table that shares a column
name in common with another table, and that you are selecting for
instances where the join is missing, that is IS NULL.
Normally, the common column name is "wiped out" by the null record, but
here is a workaround for it: You simply alias that common column name in
the select. For instance,
CREATE TABLE t1 (INT id NOT NULL, ....);
CREATE TABLE t2 (INT id NOT NULL, ....);
...
SELECT * FROM t1 LEFT JOIN t2 ON t1.id = t2.id
WHERE t2.id IS NULL;
would result in the column 'id' being null on each selected row.
Instead, you can do:
SELECT *, t1.id AS id FROM t1 LEFT JOIN t2 ON t1.id = t2.id
WHERE t2.id IS NULL;
And now the 'id' column will be preserved since the alias is evaluated
*after* the LEFT JOIN.
[/cut]
pay attention to: -> *, t1.id <-

I didn't know that.
Thanks, now I have to figure out a way to store a $_SESSION in a
cookie and read it back without inferring with what the user is
currently doing in both post and get selections. I have myself overly
confused at the moment with too much user activity.

no shit! (regarding the confusion).
$_SESSION is populated when you call session_start(), it's contents are stored
on the server. calling session_start() implicitly make php emit a cookie which
contains not much other than the session id - it's this id (that the browser
sends back in the form of a cookie again) that tell's php which chunk of
serialized data that it saved onto disk (usually onto disk) at the end a
previous request it should load up when you call session_start().
by default the session cookie is 'dropped' by the browser once you
close it [the browser]
try this, it might to help you see what's happening a bit (oh and
don't forget the manual ;-):
<?php
session_start();
if (!isset($_SESSION['myObj'])) {
echo "INIT!<br />";
$_SESSION['myObj'] = new stdObject;
$_SESSION['myObj']->counter = 1;
}
echo $_SESSION['myObj']->counter++;

Hi,
I am running a self-compiled PHP version 4.4.2 on Apache 1.3.34 on White Box
Enterprise Linux 3.
I found a problem in my database access code (Oracle 9.2.0.4 if it matters)
and have determined that spaces in string variables are being compacted on
output in PHP.
This PHP extract, when run, illustrates the problem:
<?php
$name = "Space 9";
print "<p>Length: ".strlen($name);
printf("<p>Variable: %s",$name);
print "<p>Variable: '".$name."'";
echo "<p>Variable: ".$name;
for($i=0; $i< strlen($name); $i++)
print "<p>Character: ".$i."\"$name[$i]\"";
?>
even though the string does contain 9 consecutive spaces, only one is ever
printed to the screen with echo, print or printf. There is nothing in the
documentation for these functions that I've found that says this is the
expected behavior, or how to override if one really wants those spaces
honored.
Why is this important? Well, the application this is in allows users to define
text strings that are inserted into the database with multiple consecutive
spaces, however, when constructing select lists in PHP using these same
entries the spaces are compacted, so the SELECT now doesn't match what is in
the database.
Is there a way to override this behavior?
Thanks,

I would suggest replacing spaces with their HTML equivalent ( ). You
could either store it that way, or change it when you output. Then when you
go to run the query change all instances back to space.

It is not PHP but HTML. In HTML any 'whitespace character', that is space,
tab or new line, is taken as a single whitespace character. It has nothing
to do with PHP.
You can either replace them with which prints as a space but doesn't
fall into the category of 'whitespace character' and is thus respected or
you can use the <pre> tag, which will produce a mono-spaced output with all
blanks and new lines as they come.

Geoffrey, another way of saying this is that it's only the SCREEN
RENDERING that makes multiple whitespace characters APPEAR to be a
single space. If you view the source of your page I think you'll see
all your spaces intact.
Since the multiple spaces are really there in your string, you should
be able to operate on all of them, for example using string-array functions.
In your script:
> $name = "Space 9";
>* print "<p>Length: ".strlen($name);
>
> printf("<p>Variable: %s",$name);
> print "<p>Variable: '".$name."'";
> echo "<p>Variable: ".$name;

...the lines I've marked with an asterisk should reveal the true
length of the string, including all nine spaces, even though the
screen-print functions make it look like they've been consolidated
into one space.

Thanks again. I have finally tracked down the root cause to my original
problem. I was using the select HTML construct a little too glibly. I was
using it in the form:
<?php
$name .= "Space 9";
echo "<form action='submit.php' enctype='text/plain'>\n";
echo "<select name='stationName' >\n";
echo "<option>\n";
echo "$name\n";
echo "</select>\n";
echo "<p><input type='submit' name='submit' value='Submit'>\n";
echo "<input type='reset' name='reset' value='Reset'>\n";
echo "</form>";
?>
i.e not providing a value attribute on the option construct to be passed to
the submitted form, and so the stationName contained the *rendered* string,
not the string that was input.
Thanks again to all who sent suggestions. I guess one still has things to
learn after 10+ years using HTML.
Regards,
GEQ

Hi,
Would anybody remind me how this should be achieved?
This returns all the names of the fields.
while( ($f = odbtp_fetch_field( $qry )) ) {
echo $f->name . "\n";
}
This returns the query results:
while( ($rec = odbtp_fetch_array($qry)) ) {
foreach ($rec as $var) {
echo "$var\n";
}
}
How should I connect them together? Say, the fields are 'name', 'age',
'score'. I want to print out $rec['name'], $rec['age'] and $rec['score']
rather than using $rec[0], $rec[1] and $rec[2].
Thanks in advance for any ideas,

Here's one way:
$oHandle = mysql_query($sSQL);
if (!$oHandle)
{
// error trapping goes here
}
// cycle through the records:
while ($aDataRow = mysql_fetch_array($oHandle, MYSQL_ASSOC))
{
// cycle through the fields in each record:
foreach ($aDataRow as $sField => $sValue)
{
// $sField is the field name
// $sValue is the field value
}
}

Was it mysql_fetch_array()?
Which SQL was it?
Also, are you aware that even entering an incorrect function name
at php.net will get you some "free pointers" ?

Step #1:
Create and surf to a phpinfo() file:
<?php phpinfo();?>
Check the "php.ini" setting in the top portion to see where php.ini MUST
BE for it to be read.
This directory was set at compile-time, by whomever happened to compile
the php.exe (and dll) that day.
You can't change it ; You have to live with it.
[Actually, in recent Apache versions, you can use an httpd.conf setting
to alter it, but let's not confuse things that are version-specific]
Step #2:
Find your php.ini file, and MOVE it to where phpinfo() wants it to be.
If you have no php.ini file, find the php.ini-dist file, copy it, and
rename it.
Step #3
In php.ini look at the "extensions_dir" setting.
Fix it.
One thing is clear from your output: You've GOT a lot of extensions
working, so you probably already have all of this correct.
Nevertheless, you follow the first 3 steps because that's just the way
you make SURE you have things set up like you think you have them set
up, even if it all "looks good"...
Step #4.
Compare version numbers of your mssql_php.dll and the version of PHP you
are running. You CANNOT mix-n-match old DLLs with new PHP and vice
versa. It will sometimes "work" until you happen to use the one
function that CHANGED between versions.
If you just went out and found some random mssql_php.dll to throw in the
directory, it is NOT going to work.
In recent PHP versions, I think it won't even let you screw this up, as
each module is, I think, tagged with an internal version reference
number and PHP will reject invalid DLLs. I think... But in the old
days, it was a common mistake for folks to install mis-matched DLL
versions and have all kinds of trouble.
Step #4a
Check your log files. I'm assuming ISS actually HAS logfiles... It
must have, right? Might be in system events log. Might be in an
"error_log" file next to your IIS web traffic logs. Knowing Microsoft,
it might be *ANYWHERE*... But, wherever it is, find it, and read it.
If all else fails, you can surf to PHP, and then use Explorer to search
for files changed in the past five minutes. Or, at least, I think it
will let you search in the past five minutes.
Yesterday I went looking to do that and could only find files changed in
the past day. Ugh.
I'm guessing that you might find an error message about the
mssql_php.dll being the wrong version...
Step #5.
Switch to a superior web server: Apache
:-)
Step #6.
Switch to a superior OS like Linux or FreeBSD
:-) :-) :-)
