The ReflectionMethod::isAbstract() function is an inbuilt function in PHP which is used to return TRUE if the specified method is abstract, otherwise FALSE. Syntax: 
bool ReflectionMethod::isAbstract ( void )
Parameters: This function does not accept any parameter. Return Value: This function returns TRUE if the specified method is abstract, otherwise FALSE. Below programs illustrate the ReflectionMethod::isAbstract() function in PHP: Program_1: php 
<?php

// Initializing a user-defined abstract class
abstract class Company {

    abstract function GFG();
}

// Using ReflectionMethod() over the class Company
$A = new ReflectionMethod('Company', 'GFG');

// Calling the isAbstract() function
$B = $A->isAbstract();

// Getting the value TRUE if the specified
// method is abstract, otherwise FALSE.
var_dump($B);
?>
Output: 
bool(true)
Program_2: php 
<?php
 
// Initializing some user-defined classes
class Department1 {
 
    public function hr($name) {
        return 'HR' . $name;
    }
}
class Department2 {
 
    public function coding($name) {
        return 'Coding' . $name;
    }
}
abstract class Department3 {
 
    abstract function marketing();
}

// Using ReflectionMethod() over the above classes
$A = new ReflectionMethod('Department1', 'hR');
$B = new ReflectionMethod('Department2', 'coding');
$C = new ReflectionMethod('Department3', 'marketing');
 
// Calling the isAbstract() function and 
// getting the value TRUE if the specified
// method is abstract, otherwise FALSE.
var_dump($A->isAbstract());
var_dump($B->isAbstract());
var_dump($C->isAbstract());
?>
