Hahahah, seriously, I am so stupid. Thanks :)

How would you use a foreach-loop to print key and value of an array (like `$_GET`)?

Emil 2010-07-20 13:08:20

@Emil `foreach ($_GET as $key => $value) echo "Key: $key Val: $value<br>";`

Pekka 2010-07-20 13:08:50

Thanks :) Is it really that easy? I guess I'm a n00b after all :p

Answer 3

+3 A:

There is a $_GET super global array to get all variables from query string.

// print all contents of $_GET array
print_r($_GET);

// print specific variable
echo $_GET['key_here'];

You can also use foreach loop to go through all of them like this:

foreach($_GET as $key => $value)
{
   echo 'Key = ' . $key . '<br />';
   echo 'Value= ' . $value;
}

How would you use a foreach-loop to print both key and value of $_GET?

Emil 2010-07-20 13:05:14

@Emil: See my updated answer for foreach loop.

@Emil: You are welcome ...

Answer 4

A:

The $_REQUEST variable is:

An associative array that by default contains the contents of $_GET, $_POST and $_COOKIE.

That could help

Make array of all GET-variables
