How to execute sh file by PHP from web page

Question

/root/script/test.sh

echo 'test';

/var/www/html/sh.php

<?php

echo 'start'.PHP_EOL;
echo shell_exec('/bin/sh /root/script/test.sh');
echo 'end'.PHP_EOL

If I run the PHP at local php sh.php , I got start test end , but if I run the php from url, http://example.com/sh.php , I only got start end , the script is not executed, but if I execute echo shell_exec('ls -al'); , it will show the list on web page.

Try This by using file_get_contents :

$path = file_get_contents('/root/script/test.sh');
echo shell_exec($path);
