PHP Exec

Introduction

Did you know we can run system commands through PHP?

Well not only it’s possible but also it’s very easy.

You can easily run your commands with exec function

exec

exec(command,output,result code)

command: the command you want to run. Like mkdir test

output: if there is any output for your command it will be saved on this variable

resultCode: the code that will be returned from running your command.

So let’s see a couple of examples example

Let’s create a directory called test

<?php
exec('mkdir test', $output, $resultCode);
// output is an empty array because there is no returned value
// resultCode is 0

Let’s get the user.

<?php
exec('whoami', $output, $retval);
// resultCode is 0
// output is:
// Array ( [0] => root )

see how easy it is?

The possibilities are endless!
