在php .sh文件中执行

Question

i am trying to execute in php one .sh file

this file is located in /home/update.sh

#!/bin/bash

/usr/bin/rsync -zaP '-e ssh -i /home/id_rsa_ws -v -p 6633' --del /var/www [e-mail]:/var/

execute this file working well:

cd /home/; ./update.sh;

the Problem is: i need to execute this file in php

What i already tried in php:

1 - nothing happens.

    $contents = file_get_contents('/home/distribute.sh');
    echo '<pre>';
    echo shell_exec($contents);

i tried also :

2.

    exec("cd /home/;./update.sh 2>&1",$o,$return);
    print_r($o);
    print_r($return);

Many thanks to [https://stackoverflow.com/users/1491895/barmar]

after Barmar recommendation i changed following:

A. I moved ssh key to /var/www/.ssh

B. I changed command in .sh file, me add two parameters

    -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null


    /usr/bin/rsync -zaP '-e ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i /var/www/.ssh/id_rsa_ws -v -p 6633' --del /var/www [e-mail]:/var/
