Insert and display datas from database using database

Question

What is the best php coding to insert data into database then display those data into the next page? Already tried from youtube but left me with the errors.

Answer 1

Which php version your php is ? And how old the video ?

My recomendation on insert and select query are this
http://php.net/manual/en/mysqli.quickstart.prepared-statements.php
This method are less vunerable to sql injection

Answer 2

How to know the best coding should i take since too much examples given from the website? Sorry I'm not an expert juz worrying might ruin my existing codings.

Answer 3

Try php.net they got tutorial, manual and documentation for every version.
And it seems its official php website (cmiiw)
