Using the method_exists Function

Published : November 22, 2014   •   Last Edited : November 24, 2025   •   Author : Adam Khoury
The method_exists() function will evaluate to see if the specified method exists. It returns TRUE if the method is found and FALSE if it is not. demo.php 
<?php
include_once("class1.php");
$myObj = new class1();
if(method_exists($myObj, "sayhello")){
    echo $myObj->sayhello();
} else {
    echo "sayhello method does not exist";
}
?>
class1.php 
<?php
class class1 {

    public function sayhello(){
        return "Hello";	
    }
}
?>
