Hi, i would like to know how to check whether a text input string contains space, commas or any punctuations?
Desired input: peterpan
Error input: peter pan Error input: peterpan! Error input: pet.rpan!
To replace them: [man]preg_replace[/man] [man]ereg_replace[/man] [man]str_replace[/man]
To simply check for them: [man]preg_match[/man] [man]preg_match_all[/man] [man]eregi[/man] [man]strpos[/man]
Take your pick
thanks
i found out about ctype_alnum just now.
