Getting the Get Variable's Name

Question

i have a need to get an undefined $_GET['$VARIABLE'].

so that if a link comes into item.php?changingitemstyle=10101010101010

I need to find out how to extract the name of the variable not the value.

Any ideas?

Answer 1

Use the array_keys() function to retrieve an array of the keys of an array.

Answer 2

figured it out

php function array_keys

Answer 3

$_GET is a dictionary, so you can get the keys easily enough (unless I'm misunderstanding the question):

foreach( $_GET as $var_name => $value ) {
   // Do something here
}
