What is the common issue with file uploads via HTTP in PHP?
The common issue with file uploads via HTTP in PHP is that the default maximum file size allowed for uploads is often too small. This can lead to errors when trying to upload larger files. To solve this issue, you can increase the `upload_max_filesize` and `post_max_size` directives in the php.ini file to accommodate larger file uploads.
// Increase maximum file size allowed for uploads
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');
