note 102737 added to language.types.type-juggling

I found it tricky to check if a posted value was an integer.

<?php

$_POST['a'] = "42";

is_int( $_POST['a'] ); //false
is_int( intval( "anything" ) ); //always true
?>

A method I use for checking if a string represents an integer value.

<?php
function check_int( $str )
                {
                    return  is_numeric( $str ) && intval( $str ) - $str == 0;
                }
?>
