[Ed. note: is_int() checks whether the type of the variable is an int, not the contents. If you want
to check the contents, you can use is_numeric(). ]
[Ed. note:
There is also a whole set of ctype functions which many of you might find useful:
http://www.php.net/manual/en/ref.ctype.php
]
is_int() does not work when passing strings.
This one does:
function str_is_int($str) {
$var=intval($str);
return ($str==$var);
}
