It lets you customize for example the max memory available for the PHP scripts, or the maximum execution time, or whatever PHP settings you need to edit.
Useful in particular to do quick/temporary edits, or when you don't have access to the PHP.ini file (like on some shared hosting).
What PHP settings can you modify? Those marked with PHP_INI_ALL in this list (i.e. upload_max_filesize & post_max_size are not modifiable)
Examples of what can it be used for:
- Fix problems caused by misconfigured PHP settings, when the hosting provider does not let you change them in an easy way
- Customize the error reporting level, hide errors from your site
- Set the PHP timezone
I give 4 stars for the application and all stars for the whole service.
I'll pay for it even I can't use it actually. But this is it worth.
Thank you very much.
