Summary

Usage

input|is_integer( target )

Parameters

Returns

Description

This operator checks if the input parameter or the target variable is an integer. If it is, the operator will return TRUE, otherwise FALSE will be returned. If both the input parameter and the target variable are provided, it is the target variable that will be evaluated.

Note: "is_integer" works like "is_int" in php, in other words a string with number in it will return false.
