Are there best practices for handling file size limits in PHP to avoid excessive traffic consumption?

When handling file uploads in PHP, it's essential to set a file size limit to prevent excessive traffic consumption and potential server overload. One way to achieve this is by configuring the php.ini file to specify the maximum file size allowed for uploads. Additionally, you can also validate the file size within your PHP script before processing the upload to ensure it meets the specified limit. 

// Set the maximum file size limit in php.ini
// upload_max_filesize = 10M
// post_max_size = 10M

// Validate file size before processing the upload
$maxFileSize = 10 * 1024 * 1024; // 10MB
if ($_FILES['file']['size'] > $maxFileSize) {
    echo "File size exceeds the limit of 10MB.";
    exit;
}

// Process the file upload
// Your upload logic goes here
