Function literal in PHP class

Question

Take a look at this code, please:

$array = array(
    \'action\' => function () { echo \"this works\"; }
);

class Test {
    public $array = array(
              


        

Answer 1

From the class it's a property !

Rule from properties :

Declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.

Try it like this, let me know if this works for you

<?php
$array = array('action' => function () { echo "this works"; });
class Test {
    public $arr;
    function __construct() {
        $this->arr = array("action" => function () { echo "this works too"; });
    }
    function getArr(){
        var_dump($this->arr);
    }
}

var_dump($array);
$obj = new Test();
$obj->getArr();

I dont have chance to test Your code on PHP 5.6.6, but I think this code resolve Your problem.

class Test{

    public $array;

    function __construct(){

            $this -> array = array(

                'action'    =>  function (){

                    echo 'It works too';
                }
            );
    }
}

$test = new Test();
$test -> array['action']();
