How to get the full path to php interpreter / binary without shell access

Question

How can I get the full path to php interpreter from a php script (no command line access).

What I need to do is:

$foo = \"/usr/bin/php\";
echo $foo;
         


        

Answer 1

Linux users can try the whereis command.

I had this situation with a PHP IDE.

whereis php

Answer 2

You can find the PHP binary path with this constant:

PHP_BINDIR

As of PHP 5.4, you can get the path to the executable actually running currently with this constant:

PHP_BINARY

Answer 3

its not common for a host to give root access to its users. Most probably, you can't access anything below /var/www

Answer 4

On Windows I would suggest the following snippet:

<?php
$pid = getmypid();
$output = shell_exec(sprintf('tasklist /nh /fo csv /fi "PID eq %d"', $pid));
$processInfo = explode(',', $output);
echo PHP_BINDIR . DIRECTORY_SEPARATOR . trim($processInfo[0], '"');

On unix the shell command should probably make use of ps
