Make array of all GET-variables

Question

I'm trying to make an array from all the GET-variables passed to a PHP script. So far I haven't found any way to do this.

Is this possible?

Solution 1

It's already there by default:

print_r($_GET);  // for all GET variables
print_r($_POST); // for all POST variables

PHP docs on all available superglobals

Solution 2

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;
}

Solution 3

GET variables are allready passed as an array

Solution 4

extract($_REQUEST);

Will get every variable passed by post or get and make into a new variable

Solution 5

Get all GET params by :

$all_params = $_SERVER['QUERY_STRING']

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

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