Server settings such as upload_max_filesize and post_max_size can impact the functionality of PHP scripts, especially when dealing with file uploads. To troubleshoot such issues, you can adjust these settings in the php.ini file or using ini_set() function in your PHP script to increase the maximum upload size.
