I want to remove everything(including the comma) from the first comma of a string in php eg.

Answer 1

You can also use current function:

$firstpart = current(explode(',', $print)); // will return current item in array, by default first

Also other functions from this family:

$nextpart = next(explode(',', $print)); // will return next item in array

$lastpart = end(explode(',', $print)); // will return last item in array
