I'm looking for something like the opposite of extract(), and I know its NOT compact().

Say I have a few variables

$state = "FL";
$city = "Hollywood";
$zip = "33021";

How can I make an array that uses the variables' names as the array keys:

array( "state"=>"FL", "city"=>"Hollywood", "zip"=>"33021" );

You should use the compact() function though. Such as:

$state = "FL";
$city = "Hollywood";
$zip = "33021";
$array = compact('state', 'city', 'zip');

Edit: Seems to do exactly what you need, don't know why you don't think you need it. If you're looking for something exactly opposite of extract(), such as taking all available variables and putting them into an array, you can't do that, because PHP would literally take all variables in the current scope and put them into the array. You have to specify which variables somehow.

I'm not sure if your correct or not.. but you do realize he said explicitly in the question that its NOT compact() right? –  Greg Guida Nov 16 '11 at 4:14
