[求教] 图片上传如何获取到自定义变量

This topic created in 2573 days ago, the information mentioned may be changed or developed.

需求：api 多图上传，遍历，保存到数据库一条自定义外键（如：lid ）和上传图片的 url。
问：通过上传获取到本张图片的 lid

写了个单文件上传，只能获取到上传自带变量，不得其法

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>Document</title>
</head>
<body>
	<form action="./1.php" method="post" enctype="multipart/form-data">
请选择您要上传的文件：<input type="file" name='myfile'/>
<input type="submit" value="上传文件" />
</form>
</body>
</html>

//1.php
<?php
    $imgname = $_FILES['myfile']['name'];
    $tmp = $_FILES['myfile']['tmp_name'];
    $filepath = 'photo/';
    if(move_uploaded_file($tmp,$filepath.$imgname.".png")){
        echo "上传成功";
        print_r ($_FILES);
    }else{
        echo "上传失败";
    }
?>

已自行解决，自己打印下多图片上传，发现 name 是数组的 key
```
foreach ($_FILES as $k => $v){
//name 让客户端赋 lid，则$k = lid
}
```
