Where to Find More Information
===============================

If you have any queries/problems about PHP, the online manual (you can get
an offline copy as well) is a good tool to become familiar with.

http://php.net/manual

Some Key sections of the PHP Manual:

- Installation and Configuration
http://php.net/install

- Language Reference
http://php.net/langref

- Function Reference
http://php.net/funcref

      tip: if you know the function name but forget exactly how
      it works just type the name of the function ie:
        http://php.net/array_merge

- The PHP FAQ
http://php.net/faq
</snip>
+ - Security
+ http://www.php.net/manual/en/security.php
+ Additional PHP Security References:
+ http://phpsec.org/
+ http://www.hardened-php.net/advisories.15.html

life is a game... so have fun.

Oops.

Unless you're working IT in a penal colony, I suspect that what you
really mean is that you choose to serve broken pages or no content at
all to users who don't have JavaScript enabled, whether by choice or
network requirement or software availability.

It's an interesting decision, excluding browsers with JavaScript
turned off. I can see making it in cases of specialty audiences,
such as the aforementioned penal colony, customized intranets, and
others where all of the user agents are not only predictable but
legislatable. For public websites, I feel we need to set barriers to
entrance only when necessary -- and when is that? -- consciously and
deliberately, focusing not so much on "Look at the cool things we can
do with JavaScript!" but "Whom shall we exclude from this
site?" Look a user in the eye, say, "You can't come in," and reflect
on how cool that is.

Although I still love to write client-side script, most of the energy
I used to expend on JavaScript I now devote to PHP. The server is
the great leveler of the playing field, rendering our pages
accessible to all user agents *if* our designs are sufficiently
clever. These days I mostly add JavaScript to perform functions that
are already performed server-side by PHP, purely for the advantage of
speed, but my best pages perform perfectly with JavaScript turned off.

Aside, the whole client-side/server-side debate depends on today's
internet connection response time being as slow as it is. In a few
years a seemingly sexy technology like Ajax, which appears useful
today in pages so heavy with content that whole-page reloads seem
onerous, will be one of the unbelievable jokes of yesteryear, like
RAM measured in kilobytes, 8" floppy discs, and punch cards.

Now, there's the way to think !

Don't confine yourself to the limitations of today, but rather open to the expectations of tomorrow.

Hi all,

I would like run a php-script via CLI which outputs some information to
stdout, and then go into background. I use code similar to this to fork
and to dettach the child I/O from the TTY (some error handling removed
to improve readability)

<?
echo "Hello from parent\n";

if(pcntl_fork()) {
exit;
}

posix_setsid();

fclose( STDIN );
fclose( STDOUT );
fclose( STDERR );

if(pcntl_fork()) {
exit;
}

echo "This message should NOT go to stdout of parent process\n";
?>

It works fine using PHP version 5.0.4, but when using PHP version 5.1.2
the output of the child ("This message....") goes to stdout of the
parent process. So if I do:

php test.php >output

Using PHP 5.1.2, the file contains:

---------------
Hello from parent
This message should NOT go to stdout of parent process
---------------

Can anybody explain this?
I run FreeBSD 6.0-RELEASE...

Hi,

I have a problem I can solve with some loops and if-thens, but I'm sure it
can be done with bit operations -- that would be prettier. I've tried to
work it out on paper, but I keep missing the final solution. Maybe I'm
missing something obvious...

The problem: A function tries to update an existing value, but is only
allowed to write certain bits.

There are 3 variables:
A: the existing value, eg. 10110101
B: what the function wants to write, eg. 01011100
C: which bits the function is allowed to write, eg. 00001111

With these examples, 10111100 should be written.

How do I combine A, B and C to get that result?

Thanks,
Niels

addition probably?

Btw. the result of the addition would be : 111010101

My brain needs a crutch when trying doing this kind of thing
(normally I only write hex number literally when dealing with bitwise stuff -
the conversion stuff still makes my head spin) - this is what this table is for:

128 64 32 16 8 4 2 1
1 0 1 1 0 1 0 1
0 1 0 1 1 1 0 0
0 0 0 0 1 1 1 1

and then I did this - hopefully it shows what you can/have to do:

<?php

// set some values
$oldval = 128 + 32 + 16 + 4 + 1; // 10110101
$update = 64 + 16 + 8 + 4; // 01011100
$mask = 8 + 4 + 2 + 1; // 00001111

// do a 'bit' of surgery ...
$add = $mask & $update;
$keep = ~$mask & $oldval;
$newval = $keep | $add;

// show what happened
var_dump(
        str_pad(base_convert($oldval, 10, 2), 8, "0"),
        str_pad(base_convert($update, 10, 2), 8, "0"),
        str_pad(base_convert($mask, 10, 2), 8, "0"),
        str_pad(base_convert($add, 10, 2), 8, "0"),
        str_pad(base_convert($keep, 10, 2), 8, "0"),
        str_pad(base_convert($newval, 10, 2), 8, "0")
);

heck, Davids 'result' line is more correct than mine I believe -
he uses an XOR operation where I used an OR operation - both have the same
result because the set of bits that are 'on' in the first operand are mutually
exclusive to the set of bits that are 'on' in the second operand.

First use & (bitwise-and) to mask out bits the function is not allowed to write:

$b & $c // result is 00001100 given above inputs

Then mask the bits that the function will write out of the original value - negate the mask and use & again:

$a & ~$c // result is 10110000

Then combine the two using | (bitwise-or):

($a & ~$c) | ($b & $c) // result is 10111101

Cheers!

Subject: Re: [PHP] Help with some clever bit operations

Though the result is the same, logically a bitwise OR (|) would be more
appropriate. The bitwise XOR flips bits which, since in this case one set
of them is always 0 produces the same result. The bitwise OR adds the bits.

An informal set of rules is:

&, as a filter, extracts those bits where you put ones in the mask
& sets to zero those bits where you put zero in the mask
| sets bits
^ flips the bits where you put a one.

$evenodd & 1 is true on odd numbers or otherwise tests for the rightmost
bit. Coupled with a right shift >> allows you to loop through a set of
bits.

for ($i=0;$i<32;$i++) {
 if ($bitset & 1) {
 echo "bit $i is set";
 }
 $bitset >>= 1;
}

Anyway, avoid the most significant bit. Since in PHP there are no unsigned
integers, you might get some funny result if anything makes PHP do an
automatic type conversion.

You could just do the following:

$oldval = bindec( '10110101' );
$update = bindec( '01011100' );
$mask = bindec( '00001111' );

when I was writing the reply I played with about 5 different
conversion funcs - pretty everything expect bindec() !!!

I guess i was being lazy - but then I alway think directly in hex numbers
when doing bitwise stuff (at least I use hex notation for the constant value
that I almost invariably end up creating)

anyway cheers for the lightbuld moment :-)

Well yours is at least faster since there's no function calls. Though
one can also do the following to avoid memorizing decimal bit values :)

$oldval = (1 << 7) + (1 << 5) + (1 << 4) + (1 << 2) + (1 << 0);
$update = (1 << 6) + (1 << 4) + (1 << 3) + (1 << 2);
$mask = (1 << 3) + (1 << 2) + (1 << 1) + (1 << 0);

PHP List,

Up until now, in order to get all the functions and classes I need in my
scripts, I have always made a file called "includes.php" that contains a
series of include() statements for all of the files that I want to
include. Then I just include that one file at the top of all my PHP scripts.

This system works okay, but I thought it would be better to have a
consistent naming standard, and use some kind wild card or loop to
include all the files I want. That way I can change, add, and remove
files a little easier.

All the files I want to include end with either ".class", or with
"_fns.php". ("fns" stands for "functions".)

It seems that wildcard characters are not supported in the include()
function. Some experiments and a search on the web seem to confirm this.

So then I thought what I need to do is use the readdir() function
somehow, and make an array of all files ending in ".class" or
"_fns.php", and then make a while or foreach loop to include every
required file.

I couldn't quite figure out how to do that, but in any case I wondered
if running this loop at the start of every single PHP script might be
unnecessary overhead. After all, the list of included files will only
change when I work on the system. It's not going to vary at all based on
any kind of user input or in standard usage of my web site.

What would be the recommended way of including files that will change as
I work on the system? Do most people create a function to detect the
included files, or do most people make a static list that they edit by hand?

Dave:

I group my includes per functionality, such as all dB operations (config, open, close, etc.) go into a db include folder (db_inc) and so on. I don't make large files, but rather small files limited to a specific operations. That works for me -- but, only you can figure out what works for you.

As for your code, try this:

<?php

$file_path = $_SERVER['DOCUMENT_ROOT']; // or whatever directory you want
$the_dir = opendir($file_path);

        while ($file = readdir($the_dir))
                {
                if(eregi("(\.pdf|\.html|\.htm|\.php|\.txt)$", $file)) // check the files extension:
                        {
                        $html[] = $file;
                        }
                }

closedir($the_dir);

if($html == null)
 {
 die("No files in this directory!");
 }

 sort($html);
 foreach($html as $html => $value)
 {
 echo (" $value");
 }
?>

sure in a very simplistic manner;

function __($s)
{
        $r = _($s);
        if ($r === $s) logUntranslatedStr($s);

        return $r;
}

but the php gettext extension does not seem to provide such a functionality
natively.

Best group member,

This is how I try to push files to download using headers:

header("Content-type: $file_type");
header("Content-Disposition: attachment; filename=$filename");
print $file;

It works fine in FireFox, but not that good in IE. I have been googled to
find the fix for IE, but I can not find it. Anyone with experience of this?

Hey,
Thanks for the explanation of the switches.

One part that I dont really understand is:

blah?foo=bar links
into blahfoo=bar

having a link such as blahfoo=bar is not going to
work to link to the second document...right? (I have
not really tried it, but have never seen html like the
above)

And lastly, I read on another forum discussing wget
that there is a switch that converts the dynamic pages
to static WITH a .html/.htm extention; unfortunatly he
didnt give an example of how to do this, was he just
blowing smoke or is that true?

Thanks again,
Ryan

Actually for me it didn't work until I did that conversion. You're not
sending an actual variable query, remember. You're linking to a static file
whose name on disk is "blahfoo=bar", which is a valid filename,
while "blah?foo=bar" is not (at least under Windows, although it didn't work
for me under Unix either).

man wget, and look for the -E option (aka --html-extension).

First of all I'm sorry for my english I don't know speak very well, I will
try to explain it, I hope you understain what I need.

I have two tables: centers and peoples, in table centers I have the centers
values and in table peoples I have the peoples values and in table columns
center the id corresponding the center.

db:
centers
id namec correoc telc
1 Cienfuegos safdcomo.com 4534345
2 Havana wdqcomo.com 4643765
3 Santiago dsdfcomo.com 3453453

peoples
id named center correod
cargod
1 Albert 1 dfsasdcomo.com
sfgsdfgsdfgsdfg
2 Julio 1 wdfsdfcomo.com
sadfsgfdsfgfdsg
3 Sussan 2 efgedfgcomo.com
gjfhjfhjfhjfg
4 Peter 2 fgdfdfgcomo.com
fgjhfgjgfjhjjghj

And the query and script to generate the tables for each centers list is:

$centers = mysql_query("SELECT namec FROM centers ORDER BY idc asc",
$connect);

while ($centerss = mysql_fetch_array($centers, MYSQL_ASSOC)) {
 echo "<table border=1>";
 echo "<tr>";
 echo "<td width=265 height=20 align=center
valign=middle>".$centerss['namec']."</td>";
 echo "<td width=265 height=20 align=center valign=middle><a
href=mailto:".$centerss['correoc'].">".$centerss['correoc']."</a></td>";
 echo "<td width=265 height=20 align=center
valign=middle>".$centerss['telc']."</td>";
 echo "</tr>";
 echo "</table>";
}
mysql_free_result($centers);

That's generate one table with one row and three columns for each center,
but, I would like to generate more rows and 3 columns in each table with the
named, correod and cargod of peoples corresponding the center, I mean, print
the centers values with the peoples corresponding this center, in one table
each one.

I hope you understaind what I need, if not polease let me know.

Well, I know that.

Sometimes unexpected errors happen. We write hundreds of lines of code a
day. Typos happen, I forget some includes, I type $d->appendCild() instead
of $d->appendChild(). It's all a part of the development process.

Our application makes extensive use of AJAX and JSON. Sometimes we make an
AJAX request and expect a JSON object in return, but instead a fatal error
happens (DOMDocument::appendChid() does not exist), well now we get a JSON
error because the response headers were messed up by the fatal error.

That JSON error is useless. We would rather see the real error as PHP would
have reported it on a simple webpage or command line.

Basically, we just want to trap all errors and reraise them as exceptions so
that our app's default exception handler can report them.

Thanks.

I read what you said and understand where you are coming from, but if
you call a function and it doesn't exist, your script is going to die.
The only thing you can do is just tail your error log and write unit
tests to make sure your stuff is working right. If you are on a local
machine just keep an eye on your php error log on each request and you
will see the full error message if log errors is turned on.

for fatal errors this not possible.

write test routines to check the output of requests that are usually made by
AJAX code... and made use a function like this to cover all your bases:

function PHPErrorReturned(response)
{
 // this is a bit crude and could possibly break if we are recieving
 // [content] HTML as part of the returned data.
 if ((response.indexOf('Notice: ') ||
 response.indexOf('Warning: ') ||
 response.indexOf('Fatal Error: ')) && (response.indexOf('{') != 0))
 {
 alert("Er was een fout opgetreden op de server\n"+response.stripTags());
 return true;
 }

return false;
}

String.prototype.stripTags = function (validTags)
{
var newstr = this.toString();

Cool, that sounds promising, thanks for that idea (and everyone else who
replied).

Hi all

Not really a php issue per se - sorry.
But I'm sure someone here is bound to know the answer. :-)

I have a main site that is accessible at say
"http://www.somedomain.com/somedir/" but I want visitors to be able to
access the site using simply "http://www.somedomain.com" AND for the
resulting URL displayed to STILL say "http://www.somedomain.com" and not
"http://www.somedomain.com/somedir/".

Should this be possible using the .htaccess file and some mod_rewrite rule?
Toyed around with that but couldn't get it to work.

ANY help would be greatly appreciated, thanks

P.S. Platform: Linux RedHat (running Apache)

when you finished toying did you take time to read the Apache docs on mod_rewrite?

you need *something like*:

RewriteRule ^/(.*)$ /somedir/$1 [L]

not today it isn't - U.S. Naval Observatory (http://aa.usno.navy.mil/data/docs/RS_OneDay.html)
gives me 5.23 for sunrise with the data you gave in your bug report.

I suggest you take dericks' words on it that this is a very difficult
algorithm and that this cannot easily, if at all, be 'fixed' (if it is
even actually a bug).

and besides since when were either of those govs considered trustworthy?
as far as authoritive sources are concerned they are right up there with
wikipedia and google.

and like like Einstein said - time is relative. so what is 5.22 anyway?

about as acceptable as the number of vowels in your domain name.
(it remains a fact whether one 'accepts' it or not)

What can be done to push PHP to correct this?

nothing, unless you can provide a patch.

there is a reason why php is not used to track satellites or shuttle
reentries and the like... and 60 seconds off on the sunrise calculation on some
webpage is not exactly going to stop the world from rotating is it?

Well, do you know where it is installed? I have mine installed in
/usr/local/gd so to test it I just ran gd2topng via
/usr/local/gd/bin/gd2topng it will ask for image information etc. If it
does that then you're golden.

The downside is you will need to recompile PHP.
