compact
COMPACT(3) 1 COMPACT(3)compact - Create array containing variables and their valuesSYNOPSIS
array compact (mixed $varname1, [mixed $...])
DESCRIPTION
Creates an array containing variables and their values.
For each of these, compact(3) 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(3).
Any strings that are not set will simply be skipped.
PARAMETERS
o $varname1
-compact(3) 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(3) handles it recursively.
RETURN VALUES
Returns the output array with all the variables added to it.
EXAMPLES
Example #1
compact(3) 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
)
NOTES
Note
Gotcha
Because variable variables may not be used with PHP's Superglobal arrays within functions, the Superglobal arrays may not be passed
into compact(3).
