How to Change the Upload File Size in PHP
The PHP programming language contains configuration parameters that define how much information can be uploaded to the server in a single transaction. Upload size limits must be expanded for sites that host video content, file storage or large images. You can change the upload size limit in the PHP.ini configuration file.
