[Editors note: Or simply use is_numeric() or ctype_digit() as forms pass stringed numbers, not integers] If you wish to is_int() so called values from a form or in general this would mean numbers in strings, you can just do the following [code] $nr = "203"; if(is_int($nr+0)) echo "is integer"; else echo "is not integer"; [/code] The $nr+0 will convert the string to a real numerical value in order to add 0 to it. --was-- If you wish to is_int() so called values from a form or in general this would mean numbers in strings, you can just do the following [code] $nr = "203"; if(is_int($nr+0)) echo "is integer"; else echo "is not integer"; [/code] The $nr+0 will convert the string to a real numerical value in order to add 0 to it. http://www.php.net/manual/en/function.intval.php
