I am trying to execute Linux shell command from php but there is no output on web page. If I am trying to execute the php page from linux cosole its working fine.
PHP Code:
<?php
$result = shell_exec('asterisk -rx "core show channels concise"');
$ccount =shell_exec('asterisk -rx "core show channels count"');
echo $result;
echo $ccount;
?>
Above code is not giving any output on web page. But on linux console its woking. e.g.
[abc@host sysadminman]# php myfile.php
分享 First of all your question is incomplete as you not showing what is expected output. But aside from this you are doing a few common mistakes there.
First you are testing your script as root (# php ...) but your httpd is NOT serving your scripts as root. So your tests are useless. You should switch to right user (most likely www-data and then check to run your script from shell. Most likely it will fail for one of two common reasons - insufficient permissions to run asterisk program or incomplete $PATH not pointing to the place where asterisk is.
