Removing everything but numbers in a string

[TexasMd91]

I am not sure if this is simple, But how can I remove everything in a string that is not a number.

 

Example: "f240fh02n,432534j,234l;sdcfu8904" would equal "240024325342348904"

try something like this:

 

$new_string = ereg_replace('[^0-9]', '', $old_string);

 

writing that off the top of my head here, so it might be the incorrect param order or regex.  but, theoretically, that's what you're looking for (a regex that matches anything that isn't a digit).
