Modifying $PATH for PHP system() calls

Question

I need to modify the $PATH on my mac so that PHP system() calls will recognize it.

So far I've edited the /etc/profile to include the line:

export PATH=$PATH:/Applications/MAMP/Library/bin

but if I do system('echo $PATH'); in PHP the new path doesn't show up.

Answer 1

Use the putenv function. For example, to add the current directory to the $PATH, one could use the following code :

<?php
putenv('PATH='.getenv('PATH').':.');   
echo shell_exec('echo $PATH'); /* Prints the expected result */
