[PHP] php 5 upgrade and background script on unix
Hello there, I hope someone resolved the same issue. I upgraded my server to 5.2.1 I got some script that are running background script (generally we call this technic FORKING) Ive got a web interface that running (depending the action chosen) other scripts in the background. My issue is, it doesn't work anymore since my new upgrade. So I'm using this line to run my background script from the web browser interface: /usr/local/bin/php test.php 2>&1 error.log if Im executing my script from the shell, my fork is working very fine! (Odd isn't it) I taught it could be owner and rights problems but it's not the case... Anyone got suggestions?? -- Frederic Belleudy Programmer PWIdeas ICQ #: 253-372-030 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] php 5 upgrade and background script on unix
don't fork webserver processes, granted it doesn't fix the problem, but you
really
should be doing it anyway.
I'm guessing that the pcntl extension is not compiled into the webserver php
SAPI,
it's a really big guess because you didn't supply the code you use to do the
forking with.
Ok then you want to have the fork code!
I'm doing a complete example
My script is forking on itself.
So from my browser I go on:
http://localhost/test_fork.php
My code in test_fork.php is :
$in = get_shell_args($_SERVER['argv']); // DONT PAY ATTENTION TO THAT
FUNCTION, it a made home function
if($in['bg']) {
print "HERE";
sleep(30);
}
else {
print "forking";
`/usr/local/bin/php /www/admin.gammacash.com/test/test_fork.php bg=1
2>&1 /var/log/test.log &`
}
?>
So Im assuming that the fork will get the bg argument, in this case I
should receive "HERE" in /var/log/test.log (did tail -f
/var/log/test.log while I was running the script)
I've put a sleep 30 seconds to get the fork PID number.
Unfortunately, when I do execute test_fork.php from the web, it wont
execute itself in background.
This method was running fine with my old config.
The script works perfectly because if Im executing test_fork.php from
the shell, the fork is working fine!

Re: [PHP] Forking doesn't work on php 5.2.1?
Well I think I've found the answer: the configure command is (in part): '--disable-cli' '--disable-pear' Ive got another server who is running fork script and '--enable-cli' is in the configure command. Well Ill let you know guys if it works after I've recompiled apache How comes it does work when Im executing it from the shell and not from the web??? Any explanations?

Re: [PHP] php 5 upgrade and background script on unix
Jochem:
won't it? what does it do? does it go into and endless loop and bring your
machine to a halt
by any chance? .. because by looking at it, as long as $in['bg'] is not set and
not equal to
true it's going to keep spawning sub-shells with cmdlines that call itself.
Me:
You haven't read my message? It works fine when Im running it from the shell
When I do:
`/usr/local/bin/php /www/admin.gammacash.com/test/test_fork.php bg=1 2>&1
/var/log/test.log &`
you can see bg=1
its the passing arguments!
any other suggestions?

'want' is putting it strongly - unless of course your handing out AudiRS4's
in which case 'want' is spot on.

So from my browser I go on:
http://localhost/test_fork.php
My code in test_fork.php is :
does $_SERVER['argv'] exist at all? does your error reporting include E_NOTICE?
what is the value of the ini setting 'register_argc_argv'?
FUNCTION, it a made home function
if($in['bg']) {
print "HERE"; sleep(30);
}
else {
print "forking";
`/usr/local/bin/php /www/admin.gammacash.com/test/test_fork.php bg=1
2>&1 /var/log/test.log &`
}
?>

should receive "HERE" in /var/log/test.log (did tail -f
/var/log/test.log while I was running the script)
I've put a sleep 30 seconds to get the fork PID number.
no idea how the sleep() will help.

and what is the value of the ini setting 'register_argc_argv' when running
via the php CLI SAPI?

Re: [PHP] Forking doesn't work on php 5.2.1?
Well my php.ini register_argc_argv = Off apache was configured with the option --disable-cli but cli is installed on my system and it works fine when i do execute the script from the shell so its a problem running php cli from my php apache module any other suggestions!?!??!

the value is OFF
but my other servers that is running php cli is set to OFF too...
