Call a method of an object whose name is stored in a variable - PHP

Question

This question may sound stupid, but I want this to work. I've got this code:

$data['method'] = 'get';
$this->app->$data['method']();

How can I replace $data['method'] with get but no string. I've tried this, but no luck.

$this->app->{$data['method']}();

Any idea?

php.net/manual/en/functions.variable-functions.php function example(){ echo "hello"; } $function = "example"; $function(); // will run the function "example" and show "Hello". — Rantanen

The last code you posted should work, if you're using PHP 5.4.0 and higher.

<?php

class A {
    public function foo() {
        echo "yes!";
    }
}

class B {
    public function run() {

        $this->a = new A;

        $data = [];
        $data['method'] = "foo";        
        $this->a->{$data['method']}();        

    }
}

$b = new B;
$b->run();
// Prints "yes!"

This will work:

call_user_func(array($this->app, $data['method']));

good luck.
