Intval Function in PHP

Introduction

In this article I explain the Intval() function in PHP. The Intval() function returns the integer value of a variable. You can not use the intval() function on an object.

Syntax

intval($var_name,base);

Parameter	Description
Var name	Scalar value to be converted into an integer
Base	Base for the conversion

The default base is ten.

Example

In the following example, the empty array returns the output zero and the nonempty array returns the one:

<html>

<?php

echo intval(33)." ";

echo intval(3.4)." ";

echo intval('31')." ";

echo intval('+321')." ";

echo intval('-313')." ";

echo intval(0213)." ";

echo intval('032')." ";
