is_uploaded_file() FunctionThe is_uploaded_file() function in PHP is used to verify whether a file has been uploaded using a web form or not. It's a crucial function for handling file uploads in PHP-based applications.
💡 Pro Tip: Before using is_uploaded_file(), make sure you've set up your HTML form to handle file uploads and sent the uploaded file data to the PHP script using the POST method.
The is_uploaded_file() function has one required parameter: the name of the uploaded file as submitted in the HTML form. Here's the basic syntax:

<?php
if (isset($_FILES['uploaded_file'])) {
if (is_uploaded_file($_FILES['uploaded_file']['tmp_name'])) {
echo "The file was uploaded.";
} else {
echo "The file was not uploaded.";
}
} else {
echo "No file was uploaded.";
}
