Definition and Usage
This function 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.
Paramters

Return Value

Example

<?php
$city = "San Francisco";
$state = "CA";
$event = "SIGGRAPH";
$result = compact("city", "state", "event");
print_r($result);
?>
|
This will produce following result:
