How to take an input from the user in php? like we use scanf in C to take input from the user..

Answer 1

it is server side language, you have to use html to get user input and than use input value like

<textarea name="hello"></textarea>

you can use $_GET['hello'];

you can also use $_POST.

Answer 2

what is the difference between $_get and $_post?

Answer 3

in url
google.com\?q=search+aditya

$_GET['q'];
using get method it shows in url like q has been shown. But in Post method it send directly to server script. Post is more secure than get. But every thing is important choose what you want to use.
