The ReflectionClass::isIterateable() function is an inbuilt function in PHP which is used to check if the defined class is iterateable or not.

Syntax:

Return Value: This function returns TRUE if the defined class is iterateable, otherwise FALSE.

Below programs illustrate the ReflectionClass::isIterateable() function in PHP:

class p implements Iterator {
    public function rewind() {}

    public function key() {}
}
  
// Using ReflectionClass() over the 
// class p
$class = new ReflectionClass('p');
  
// Calling the isIterateable() function
$A = $class->isIterateable();
  
// Getting the value true or false
var_dump($A);
?>


Output:

bool(true)

Program 2:




<?php
  
// Creating an iterating class p
