compact
(PHP 4, PHP 5)
compact — Create array containing variables and their values
Description
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().
Any strings that are not set will simply be skipped.
Parameters
-
varname
-
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.
Return Values
Returns the output array with all the variables added to it.
Examples
Example #1 compact() example
<?php
$city = "San Francisco";
$state = "CA";
$event = "SIGGRAPH";
$location_vars = array("city", "state");
$result = compact("event", "nothing_here", $location_vars);
print_r($result);
?>
The above example will output:
Array
(
[event] => SIGGRAPH
[city] => San Francisco
[state] => CA
)
