PHP file upload method

How to implement file upload in php

1. Create a form and file type input and set the form attribute "enctype" to "multipart/ form-data";

<form action="./upload_file.php" method="post" enctype="multipart/form-data">
    <input type="file" name="upfile">
    <button type="submit">上传</button>
</form>

2. Save the submitted file through the "move_uploaded_file" function in the PHP program.

$filename = $file_tmp = $_FILES['upfile']['name'];
$file_tmp = $_FILES['upfile']['tmp_name'];

move_uploaded_file($file_tmp, 'Uploads/' . $filename);
