Safe in php5.3

When I restarted nginx today, I found the following error: PHPWarning: Directivesafe_modeisdeprecatedinPHP5.3andgreaterinUnknownonline0PHPWarning: warning.

When I restarted nginx today, I found this error.

PHP Warning: Directive 'safe _ mode' is deprecated in PHP 5.3 and greater in Unknown on line 0
PHP Warning: Directive 'Magic _ quotes_gpc 'is deprecated in PHP 5.3 and greater in Unknown on line 0

Unknown on line 0

I went to the official website and noted it with the red block. php5.3 does not recommend this stuff anymore. It has been discarded in PHP6:

Magic_quotes_gpc boolean
Warning
This feature has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 6.0.0. Relying on this feature is highly discouraged.

In magic_quotes_gpc = on configuration, Magic quotes automatically escapes data when inserting data. To a certain extent, the security risks of scripts can be removed from beginners. For example, if you enable Magic quotes without any protection measures, there will be fewer risks, such as injection problems. I have read some security articles in the past. Intruders always like to choose magic_quotes_gpc = off. If they see its magic_quotes_gpc = on, it is estimated that they will not get this site.
So why should the Government abolish this stuff? After searching, I can see a post that is quite detailed and comprehensive. I will post the following reasons:
Why not use Magic quotes?

Portability
Whether or not this function is enabled affects the portability of scripts because it affects subsequent data filtering operations.

Performance problems
It is escaped before obtaining all external data, which will undoubtedly increase the runtime cost (and not all data needs to be escaped ).

Confusions
As mentioned above, not all data needs to be escaped. One possible scenario is when you use the stripslashes function "crazy" to get unescaped data.
