php - How to set $_GET variable

Question

How do i set the variable that the $_GET function will be able to use, w/o submitting a form with action = GET?

Answer 1

$_GET contains the keys / values that are passed to your script in the URL.

If you have the following URL :

http://www.example.com/test.php?a=10&b=plop

Then $_GET will contain :

array
  'a' => string '10' (length=2)
  'b' => string 'plop' (length=4)

Of course, as $_GET is not read-only, you could also set some values from your PHP code, if needed :

$_GET['my_value'] = 'test';

But this doesn't seem like good practice, as $_GET is supposed to contain data from the URL requested by the client.
