Ok, let's say I have a string that is CSV: 01,02,05,10,11,13.. what would be the easiest way to remove the leading zeros?

Use
preg_replace
for this:$text = "01,02,05,10,11,13,101"; echo preg_replace('/(?<=,|\b)0([0-9])/', "$1", $text);
EDIT: Updated the regex to work with numbers with a
0
in the middle of them. (i.e. 101)
Thanks to @BoltClock for helping fix the regex.Output:
1,2,5,10,11,13,101
The advantage to doing it this way is you don't have to mess with turning all the text into an array, modifying it/looping through it, and then turning it back into text.
