Are there any specific PHP settings or configurations that could be affecting the file download process?
If file downloads are not working properly in PHP, it could be due to limitations set in the php.ini file. Specifically, the "max_execution_time", "memory_limit", or "post_max_size" settings could be affecting the download process. To resolve this, you can try increasing these limits in the php.ini file or using the ini_set() function within your PHP script.
// Increase max_execution_time, memory_limit, and post_max_size settings
ini_set('max_execution_time', 300);
ini_set('memory_limit', '128M');
ini_set('post_max_size', '8M');
