PHP closure function parameters and methods of using external variables

In this paper, we describe the parameters of PHP closure function and the methods of using external variables. Share to everyone for your reference, as follows:

In the Laravel controller write two methods, one is to create a closure function in the internal, one is to execute the passed closure function, test the closure of the wording, use the external variables, and the closure function of the parameters. As follows:

Test closed Bao and use external variables public function testclosure ($t 1, $t 2) {  $closure = function ($param 1, $param 2) using ($t 1, $t 2) {    echo $param 1. $param 2. $t 1. $t 2;  };  $this->execclosure (' test.closure ', $closure);} Executes the closure function protected functions execclosure ($name, Closure $closure) {  echo ' Closure func name: '. $name;  Echo '
';  $closure (' P1 ', ' P2 ');}

To add a route in routes.php:

Copy the Code code as follows:

Route::get ('/test/closure/{t1}/{t2} ', [' uses ' = ' testcontroller@testclosure ']);

Visit www.example.com/test/closure/hehe1/hehe2

The results of the browser output:
