call_user_func
Posted on March 27th, 2010 No commentsThe call_user_func() function in PHP calls a user defined function as specified by the first parameter. You can also use call_user_func() to call an instance method of an object by using an array(instance, methodName) parameter as follows:
PHP
class User{ private $name = null; public function __construct($name){ $this->name = $name; } public function getName(){ return $this->name; } } $user = new User('Shaymol'); echo call_user_func( array($user, 'getName') ); // => Shaymol
To get same behavior in Ruby we can call the send() method of an object as follows:
Ruby
# define a user class class User attr_accessor :name def initialize(name) @name = name.capitalize end end # create a user object user = User.new('Shaymol') # this is similar to user.name, and in PHP similar to call_user_func($obj, 'methodName'); puts user.send(:name) # => Shaymol
