So,does PHP hold information as a database

Question

I mean,you process forms through PHP, like let's say, username and password. But, where is that information exactly,a separated database such as SQL,on the HTML file,on the PHP file? Can someone throw some light on this ?

Answer 1

If you are using LocalHost, your SQL database will be inside PHPmyAdmin.

And with the use of PHP, you can manipulate that database.
In order to do that you need to install xamp server on your computer.
Than you can create a database and easily maintain it.

For example(PHP file):
<?php
$query = "select * from test";
//And then you need to connect database.
?>
