                                    compact

   (PHP 4 )
   compact --  Create array containing variables and their values

Description

   array compact ( mixed varname [, mixed ...])

   compact() takes a variable number of parameters. Each parameter can be
   either a string containing the name of the variable, or an array of
   variable names. The array can contain other arrays of variable names
   inside it; compact() handles it recursively.

   For each of these, compact() looks for a variable with that name in
   the current symbol table and adds it to the output array such that the
   variable name becomes the key and the contents of the variable become
   the value for that key. In short, it does the opposite of extract().
   It returns the output array with all the variables added to it.

   Any strings that are not set will simply be skipped.

   Example 1. compact() example
   <?php
   $city  = "San Francisco";
   $state = "CA";
   $event = "SIGGRAPH";
   $location_vars = array("city", "state");
   $result = compact("event", "nothing_here", $location_vars);
   ?>

   After this, $result will be:
   Array
   (
       [event] => SIGGRAPH
       [city] => San Francisco
       [state] => CA
   )

   See also extract().
