$_FILES in PHP

PHP global$_FILES contains all the information of the file. With the help of $_FILES global variables we can get the file name, file type, file size, temporary file name and file related errors.

PHP $_FILES is a predefined array used to obtain information about files uploaded through the POST method. If uploading a single file, then $_FILES is a two-dimensional array; if uploading multiple files, then $_FILES is a three-dimensional array.

1. Create a file.html demo upload file, the code is as follows:

<html>
<head></head>
<body></body>
<form enctype="multipart/form-data" action="file.php" method="POST">
    Send this file: <input name="userfile" type="file" />
                    <input type="submit" value="Send File" />
</form>
</html>

Copy after login

<?php
    echo "<pre class="brush:php;toolbar:false">";
    print_r($_FILES);
?>
