What potential issues can arise when trying to access and modify the php.ini file on a shared hosting server?

Potential issues that can arise when trying to access and modify the php.ini file on a shared hosting server include limited permissions to access the file, restrictions set by the hosting provider, and the risk of breaking other users' websites on the same server. To solve this issue, you can try using the ini_set() function within your PHP code to override specific PHP configuration settings without needing to modify the php.ini file directly.

// Override PHP configuration settings using ini_set()
ini_set('setting_name', 'new_value');
