Development Can I execute a bash script from php? (not sh)

Every time I use any of PHP's built in exec() functions it launches sh, which on my Ubuntu server is symlinked to dash.

I have added:

Code:

#!/bin/bash

to the top of my .sh file, and even told PHP to exec("bash myScript.sh"); but still no dice.

I'd love to just have all of my scripts execute using bash instead of sh.

tips? advice?

 

Works beautifully:

PHP:

$arp = exec("/usr/sbin/arp -a|sed 's/ /,/g'>arp.csv", $output, $exit_code);

Lesson:
don't name your output files the same as the command you use to get them!
