I am running the following php script:
<?php
ini_set('display_errors', 'On');
error_reporting(E_ALL);
date_default_timezone_set('UTC');
echo nl2br("Before\n\n");
$out = shell_exec("ls -lart");
echo "<pre>$out</pre>";
echo nl2br("After\n\n");
?>
I cannot get shell_exec
or exec
to work at all. The script above produces:
Before
After
but nothing in between.
I think shell_exec
function is disabled in your php.ini . You can check it by
if(function_exists('shell_exec')) {
echo "shell_exec is enabled";
} else {
echo "shell_exec is disabled";
}
Open your php.ini and navigate to section disable_functions
If shell_exec is listed under there , remove it.
Then restart apache / php handler.
Also If Safe Mode is enabled this function will not be available. You need to disable it.
