What is the significance of the post_max_size configuration in PHP and how does it affect file uploads?
The post_max_size configuration in PHP determines the maximum amount of data that can be sent in a POST request. This directly affects file uploads because when a file is uploaded through a form, it is sent as part of a POST request. If the uploaded file size exceeds the post_max_size limit, the file upload will fail. To fix this issue, you need to increase the post_max_size value in your PHP configuration.
// Increase the post_max_size value in php.ini
post_max_size = 20M
