Text filtering feature?

Question

PHP

Hello.
Can you suggest a function or a set of functions to adequately filter the text sent by the user (from SQL injections, html codes, single quotes, etc.)
I know that there are strip_tags and other methods, but maybe someone wrote or found a function to clean up the code from unnecessary ?
I wrote a couple of modules for the engine, but after going through the security I found a lot of errors. For example, if you send a single quote, we get a MySQL Fatal Error, we had to write a regular expression, but then send a backslash with a quote - the same problem occurs.
In other words, it is not able to foresee all errors, therefore, in search of a suitable function.
Thanks in advance.

Answer 1

Use PDO, or mysqli_escape_string to write to the database, this will be enough.
You can also use HTML Purifier if you need "something more than".

Answer 2

regex + "whitelist" characters

Can not be.
On the other hand, this is not necessary.
You don't work with queries like you would with strings: https://habrahabr.ru/post/148701/
Display data with a template engine: twig.sensiolabs.org
This is enough, and no special protection is needed.
