5 Correct Methods to Increase Upload Attachment Size in WordPress

Hello everyone, I am Brother Lei Feng. Recently, Brother Lei Feng helped someone build a website that required uploading large video files. WordPress's media file upload limit is typically within 50M, which depends on your installed environment configuration.

After searching online for tutorials, many are incorrect. Some even suggest adding @ini_set( 'upload_max_size' , '64M' ); in functions.php, which is actually useless. The most correct method is to modify the php.ini file + the configuration files for nginx / Apache. Below, I'll explain how to modify them.
