Running shell commands in a .php file from the command line

Question

I have a series of shell commands that I want to put into the program and execute the program from the command line. I decided to use PHP for this, so I'm currently trying to run most shell commands.

Save as build.php

<?php
shell_exec('cd ..');
echo "php executed\n";
?>

From the command line

php build.php

Exit

php executed

Php is executing correctly, but I'm still in the same directory. How to get shell_exec (...) to successfully invoke a shell command?
