How to Upload Multiple Files Using HTML and PHP via HTTP POST?

Uploading Multiple Files with HTML and PHP via HTTP POST

Problem:

Users want to select and upload multiple files at once using a single input control, utilizing HTML and PHP via HTTP POST.

Solution:

HTML5 introduces the multiple attribute for the element, enabling the selection of multiple files. Here's an example:

<input type="file" name="my_file[]" multiple>

In PHP, the uploaded files information is accessible in the $_FILES array. The following code demonstrates how to loop through and display the details:

<?php if (isset($_FILES['my_file'])) {
    $myFile = $_FILES['my_file'];
    $fileCount = count($myFile["name"]);

    for ($i = 0; $i < $fileCount; $i++) {
        echo "<p>File #" . ($i + 1) . ":";
        echo "<p>";
        echo "Name: " . $myFile["name"][$i] . "<br>";
        echo "Temporary file: " . $myFile["tmp_name"][$i] . "<br>";
        echo "Type: " . $myFile["type"][$i] . "<br>";
        echo "Size: " . $myFile["size"][$i] . "<br>";
        echo "Error: " . $myFile["error"][$i] . "<br>";
        echo "</p>";
    }
}
?>

Example:

    
        <title>Test</title>
    
    
        

<input type="file" name="my_file[]" multiple>

Upon selecting multiple files and submitting the form, the PHP code will process each file individually, displaying its details.

Note: Proper handling of file uploads in PHP, including security considerations and error checking, is essential and should be implemented in real-world applications. Refer to the PHP Manual for more information.
