asterisk users - Jun 2009 - PHP AGI Not Working and Odd Behavior

Hi,

I'm running asterisk 1.4.22 on a debian server.
I have php5 installed and it works correctly command line.
When trying to run a php script via AGI, I get messages such as:
GI Tx >> I>
AGI Rx << #!/usr/bin/php5 -q
AGI Tx >> 510 Invalid or unknown command

The scripts are completely executable and owned by asterisk
-rwxr-xr-x 1 asterisk asterisk

Googling is not helping much, and php seems installed perfectly. Other 
servers running the same AGIs have no such problem.

I also have noticed odd behavior. When I edit an AGI, the changes aren't 
always showing up in the running of the script via asterisk.
For example, I tried editing the bash command to read #!/usr/bin/php -q, 
and got the same response on my agi debug.
I know for a fact it's running the script I've edited:
 Launched AGI Script /var/lib/asterisk/agi-bin/myscript.php
and it's not in some other directory.

Any input: obvious or not is requested...a few people here are stumped!

Thank you!

Keep in mind that if you change your dialplan to call a different
script you will need to
cli> dialplan reload

Other than that, I'm not sure that it's legal to put an argument into
a shbang, as in your -q when launching php.
It's also possible you've somehow locked down php or directories way
too much. The proper test is to:
bash$ sudo -u asterisk /path/to/script.php

Thanks.
I didn't change anything in my dialplan. I am aware of reloading
configuration :)

My AGIs are copied from a working asterisk install -- the shebang argument is
how I've always done it. Either way, I have tried it without the -q as well,
and that also didn't succeed.

I just tried your test and it worked fine to run it.

As I said, I know the server is reading the file I've been editing. I see it
on the monitor. It's definitely opening the file to return that message...

Any other ideas?

I think I got it. ${DIALEDPEERNUMBER} contains the leg that connected
(just what I need).
FYI I used DumpChan() to get all the available variables and found it.

Thanks!

May be a  total red herring (I'm using an old version of Trixbox)
but if I edit my PHPs on a Windows machine and upload using FTP, they
will only run if I fire up Nano and save the file on the Asterisk box.

Thanks for the suggestion, but I'm editing directly on the server....

I've been doing AGIs for, what, 4 years now? I have never been *this*
stumped!

I think I found the part of my AGI the script is stuck at.

The #!/usr/bin/php command was fine. What the agi debug I believe is 
displaying is the output of this:
 $in = fopen("php://stdin","r");

Which explains what I thought was "cached"
 -- the same #!/usr/bin/php5 -q command repeatedly failing was NOT the 
opening of my script, but rather the <stdin>

I'm going to play around more with this, but in case anyone has a 
similar problem, they'll have a starting place.

Thanks!

Are you by any chance mounting two volumes to the same path?
Do you use a PHP opcode cache?
Did you try to reboot the system?
Strange filesystem?
