PHP list() function

Php list() function to assign to the variables to the array.

$user = ['mark Thomas', 'mark@gmail.com'];
list($name, $email) = $user;
Instead of:
$name = $user[0];
$email = $user[1];

PHP compact() function

compact() function to create quickly an array using key as the variable name.

$name = 'mark Thomas';
$email = 'mark@gmail.com';
compact('name', 'email');
Instead of:
['name' => $name, 'email' => $email]

    $var = "something";
}
