Re: [PHP4BETA] is string numeric

Faisal: I do not think that any of the functions you listed do what this guy is looking for, do they? E.g., is_integer is our best shot.... <?php $a = "12345"; print "is_integer(\$a)? " . is_integer($a) . "\n\n"; ?> Returns: is_integer($a)? If I am not mistaken, this guy is looking for PHP equiv. to C's isdigit. --Joey Smith On Thu, 16 Mar 2000, Faisal Nasim wrote: > LI.
