Pass arguments from array in PHP to constructor

PHPServer Side ProgrammingProgramming

The Reflection API can be used to pass arguments from array to constructor.

ReflectionClass::newInstanceArgs

The above line creates a new class instance from given arguments −

public ReflectionClass::newInstanceArgs ([ array $args ] ) : object

It creates a new instance of the class when the arguments are passed to the constructor. Here, args refers to the arguments that need to be passed to the class constructor.

Example

 Live Demo

<?php
   $my_class = new ReflectionClass('ReflectionFunction');
   $my_instance = $my_class->newInstanceArgs(array('substr'));
   var_dump($my_instance);
?>

Output

This will produce the following output −

object(ReflectionFunction)#2 (1) { ["name"]=> string(6) "substr" }
