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. The upload limit for WordPress media files is typically within 50M, which is related to your installed environment configuration.

After searching online for tutorials, many were incorrect. Some even suggested adding @ini_set( 'upload_max_size' , '64M' ); in functions.php, which is actually ineffective. The most correct method is to modify the php.ini file along with the configuration files for nginx/Apache. Below, I'll explain how to make these modifications.
