将PHP变量传递给远程bash脚本

Question

Is there a method similar to PHP's GET for bash scripts?

This is what I'm trying to do...

PHP file sets a variable and executes a remote bash script, the variable gets passed and is used in the bash script.

So this is my PHP script...

 <?php
 $myvar = 'hello world';

 $connection = ssh2_connect('example.com', 22);
 ssh2_auth_password($connection, 'username', 'password');

 $stream = ssh2_exec($connection, '/usr/incoming/myscript.sh');
 ?>

And this is myscript.sh on the remote machine...

 #!/bin/bash          
 echo $myvar

Of course this isn't working because I'm not sure how to pass $myvar from the PHP file to myscript.sh

I know with PHP this is done using GET but how do I do this in this situation?

Answer 1

I recently published a project that allows PHP to obtain and interact with a real Bash shell, even through SSH. Get it here: https://github.com/merlinthemagic/MTS

After downloading you would simply use the following code:

$shell = \MTS\Factories::getDevices()->getRemoteHost('example.com')->getShellBySsh('username', 'secretPassword');

//instead of triggering a script, just trigger the individual commands i.e.:
$return1  = $shell->exeCmd("echo \$myvar");

Answer 2

As @Phylogenesis commented, you want to simply put the variables after the script call, then call in the bash script use $1 to read the var:

$stream = "/usr/incoming/myscript.sh " . escapeshellarg($myvar);

Your bash script would look like:

#!/bin/bash          
 echo "$1"

script.php

 <?php
 $myvar = 'hello world';
 $myvar = escapeshellarg($myvar);
 $connection = ssh2_connect('example.com', 22);
 ssh2_auth_password($connection, 'username', 'password');
 $stream = ssh2_exec($connection, '/usr/incoming/myscript.sh '.$myvar);

myscript.sh

#!/bin/bash          
echo $1
