How can the "upload_limit" variable in the php.ini be bypassed on a shared server?

To bypass the "upload_limit" variable in the php.ini on a shared server, you can use the "ini_set" function in PHP to dynamically change the upload limit for the current script execution. This allows you to temporarily increase the upload limit without directly modifying the php.ini file.

// Set a higher upload limit temporarily
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '20M');
