PHP Closed-Package function and the method of using external variables _php tips

This article describes the PHP closure function parameters and the use of external variables method. Share to everyone for your reference, specific as follows:

Write two methods in the Laravel controller, one is to create a closure function internally, one is to perform the closure function, test the closure of the writing, use external variables, and closure function of the reference. 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 ', $closure);
}
Execute closure functions
protected function Execclosure ($name, Closure $closure)
{
  echo ' Closure func name: '. $name;
  Echo ' <br> ';
  $closure (' P1 ', ' P2 ');
}

To add a route to routes.php:

Copy Code code as follows:

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

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

Browser Output results:

Closure func name:test.closure
