Regex allows only 1 character

Question

$rex = \'/^[^<,\"@?=>|;#]$/i\';

I\'m having trouble with this regular expression. The idea is that the input fields are checked for certain chara

Answer 1

You're asking for only one character. If you want multiple characters, get the pattern repeated, either like this (one or more times):

 $rex = '/^[^<,"@?=>|;#]+$/i';

or like this (zero or more times):

 $rex = '/^[^<,"@?=>|;#]*$/i';
