如何使用Swift iOS将照片插入到使用PHP的MySQL数据库中

我试图使用带有swift的php文件将照片插入数据库，但我只能将照片添加到htdocs“uploads”下的文件中，但无法将路径添加到数据库中。 有人能告诉我如何在swift知道我使用了本教程的情况下，将带有参数的照片添加到数据库中吗

这是我的密码：

            appendData(data!)

        }



    }

这里是PHP文件，我无法在其中插入照片数据

<?php

$firstName = $_POST["firstName"];

$lastName = $_POST["lastName"];

$userId = $_POST["userId"];



$target_dir = "uploads/";if(!file_exists($target_dir))

{

mkdir($target_dir, 0777, true);

}



$target_dir = $target_dir . "/" . basename($_FILES["file"]["name"]);



if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_dir)) 

{



echo json_encode([

"Message" => "The file ". basename( $_FILES["file"]["name"]). " has been uploaded.",

"Status" => "OK",

"userId" => $_REQUEST["userId"]

]);



} else {



echo json_encode([

"Message" => "Sorry, there was an error uploading your file.",

"Status" => "Error",

"userId" => $_REQUEST["userId"]

]);



}
