In addition to the RegEx note made before, I would give you a slight
example (rather common) in case you're not already done:

check out the
preg_match(http://php.net/manual/en/function.preg-match.php) with some
RegExp like "/[a-zA-Z0-9 ]+/", which would give you true only of case
of digits and letters and blank space. The + will assure that there is
at least one letter/digit.

For more info check the user-contributed notes in the link above. It's
not a big deal...

Good day.
