A regex to match strings with alphanumeric, spaces and punctuation

rated 0 times [ 63] [ 7] / answers: 1 / hits: 56086 / 13 Years ago, mon, august 29, 2011, 12:00:00

I need a regular expression to match strings that have letters, numbers, spaces and some simple punctuation (.,!'/$). I have ^[A-Za-z0-9 _]*[A-Za-z0-9][A-Za-z0-9 _]*$ and it works well for alphanumeric and spaces but not punctuation. Help is much appreciated.

Just add punctuation and other characters inside classes (inside the square brackets):

[A-Za-z0-9 _.,!'/$]*

This matches every string containing spaces, _, alphanumerics, commas, !, ", $, ...
Pay attention while adding some special characters, maybe you need to escape them: more info here
