[PHP] validating input

I want to check a string for only numbers and letters but am banging my head with regex: $good = joh_'; // Let's check the good e-mail if (preg_match(/[a-z0-9]/, $good)) { echo Good; } else { echo Bad; } This returns Good, why? Thanks! -- PHP General Mailing List

[PHP] Validating input

I've been looking at the docs and found preg_match and preg_match_all but these functions only seem to match 1 specific search item. I want to make sure a variable (say $mlsnumber) contains only numbers and no spaces. What would I use to accomplish this? Thanks Ed -- PHP General Mailing List
