Pass an Array as a URL Parameter in Laravel

To pass an array as URL parameter you can make use of php built-in function http_build_query(). The http_build_query() returns you an URL-encoded query string.

Example 1

Using http_build_query()

Following is an example of this method ?

$data = array(
   'field1' => 'test',
   'field2' => 'xyz'
);
echo http_build_query($data) . "
";

Output

The output of the above code is ?

field1=test&field2=xyz

The following example shows how to make use of http_build_query() when you have an array and the same needs to pass as a URL parameter.

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Http\Response;

class UserController extends Controller{
   public function index(Request $request) {
      $yoururl = "https://www.test.com";
      $params = array(
         "t1" => "abc",
         "t2" => "xyz"
      );
      echo $yourfinalurl = $yoururl."?".http_build_query($params);
   }
}

The output of the above code is ?

https://www.test.com?t1=abc&t2=xyz

Example 2

You can make use of serialize() and urlencode PHP built-in function to pass an array as URL param.

The serialize() function will return a sequence of bits for the input given and the urlencode will again encode the values as well the special characters available in it.

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Http\Response;

class UserController extends Controller{
   public function index(Request $request) {
      $yoururl = "https://www.test.com";
      $params = array(
         "t1" => "abc",
         "t2" => "xyz"
      );
      $firstserialize = serialize($params);
      echo $yourfinalurl = $yoururl."?".urlencode($firstserialize);
   }
}

Output

The output of the above code is ?

https://www.test.com?a%3A2%3A%7Bs%3A2%3A%22t1%22%3Bs%3A3%3A%22abc%22%3Bs%3A2%3A%22t2%22%3Bs%3A3%3A%22xyz%22%3B%7D

Example 3

Making use of http_build_query() and urlencode() functions.

• urlencode() ? it will encode the values into a string.

• http_build_query() ? returns you an URL-encoded query string.

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Http\Response;

class UserController extends Controller{
   public function index(Request $request) {
      $yoururl = "https://www.test.com";
      $params = array(
         "t1" => "abc",
         "t2" => "xyz"
      );
      echo $yourfinalurl = $yoururl."?".urlencode(http_build_query($params));
   }
}

Output

The output of the above code is ?

https://www.test.com?t1%3Dabc%26t2%3Dxyz

Example 4

Using urlencode() and jsonencode()

Following is an example to pass an array as a URL parameter using jsconencode() and urlencode() functions ?

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Http\Response;

class UserController extends Controller{
   public function index(Request $request) {
      $yoururl = "https://www.test.com";
      $params = array(
         "t1" => "abc",
         "t2" => "xyz"
      );
      echo $yourfinalurl = $yoururl."?".urlencode(json_encode($params));
   }
}

Output

The output of the above code is ?

https://www.test.com?%7B%22t1%22%3A%22abc%22%2C%22t2%22%3A%22xyz%22%7D
