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
)
|
