如何在Laravel中傳遞陣列作為URL引數？

---

要將陣列作為URL引數傳遞，您可以使用PHP內建函式http_build_query()。http_build_query()函式返回一個URL編碼的查詢字串。

示例1

使用http_build_query()

以下是此方法的示例：

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

輸出

以上程式碼的輸出為：

field1=test&field2=xyz

以下示例演示了當您有一個數組需要作為URL引數傳遞時，如何使用http_build_query()。

<?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);
   }
}

以上程式碼的輸出為：

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

示例2

您可以使用serialize()和urlencode PHP內建函式將陣列作為URL引數傳遞。

serialize()函式將返回給定輸入的位序列，而urlencode將再次對值以及其中可用的特殊字元進行編碼。

<?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);
   }
}

輸出

以上程式碼的輸出為：

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

示例3

使用http_build_query()和urlencode()函式。

• urlencode() - 它將值編碼為字串。

• http_build_query() - 返回URL編碼的查詢字串。

<?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));
   }
}

輸出

以上程式碼的輸出為：

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

示例4

使用urlencode()和jsonencode()

以下是一個使用jsconencode()和urlencode()函式將陣列作為URL引數傳遞的示例：

<?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));
   }
}

輸出

以上程式碼的輸出為：

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