PHP exec/shell_exec/system not working through browser
10,506
try
$output = shell_exec('ls /tmp/ 2>&1')
you might be having an issue with permissions to current directory for the user running the web page.
you can also try whoami
command.

I am running an SCO Unix box with apache version 1.3.33 and PHP version 4.4. I can properly execute the exec command through the cli, but run into trouble with trying to execute the script via a browser. My settings are:
- safe mode off
- full read/write/exec permissions
- displaying all errors
- no disabled functions
My code: test_script.php in htdocs dir
<?php exec('ls',$out,$rval); echo "Output:<hr />"; print "<pre>"; print_r($out); print "</pre>"; echo "Return Value:<hr />"; echo $rval; ?>
I've tried setting the executable binary path explicitly also. The test script is the same User/Group as apache. I've also tried adding 2>&1 to the arg, but see no change. Thank you in advance.
