`compact()` Function in PHP 8.2, PHP 8.3 & PHP 8.4

The `compact()` function in PHP is used to create an associative array using variable names as keys and their corresponding values. It helps in dynamically constructing arrays from existing variables.

Syntax:

array compact(mixed $var_name, mixed ...$var_names)

Example:

<?php
$name = "John";
$age = 30;
$city = "New York";
$result = compact("name", "age", "city");
print_r($result);
?>

Output:

Array
(
[name] => John
[age] => 30
[city] => New York
)
