Check for space and Characters

[jamesm87]

Hi

I would like to determine if a space or any characted except a-z or 1-9 is in a variable.

Can some one please tell me how I can do this.

Thanks in advance 🙂

if (preg_match("/[^a-z1-9]/", $var)) {

Though I wonder if you meant:

if (preg_match("/[^a-z0-9]/i", $var)) {
