PHP is_numeric or preg_match 0-9 validation

Question

This isn\'t a big issue for me (as far as I\'m aware), it\'s more of something that\'s interested me. But what is the main difference, if any, of using is_numeric

Answer 1

Meanwhile, all the values above will only restrict the values to integer, so i use

/^[1-9][0-9\.]{0,15}$/

to allow float values too.
