How Would I Remove all instances of this?

[catlover]

I want to remove every instance of this that I find:

Ad ID: 12323500

....where "Ad ID: " will always be the same, but the number after it will always be different. It will always be a 8-digit number though.

I'm a php newb and I usually just use str_replace to get rid of stuff I don't want but wasn't sure how to approach it in this situation.

Thank you!!

use preg_replace instead of str_replace so you can use a regular expression.

The following regul;ar expression will match every occurrence of your Ad ID provided that it is followed by an eight digit number

/Ad ID: \d{8}/
