print_r() Function CODE
➤ The print_r() function prints the information about a variable in a more human-readable way. Syntax: 
print_r(variable, return);  // second parameter is optional
For instance: 
$cars = array("BMW", "Ferrari", "Mustang");
print_r($cars);
$names = array("Keira Knightley"=>"37", "Mads Mikkelsen"=>"56", "Keanu Reeves"=>"58");
print_r($names);
/* outputs:
Array
(
    [0] => BMW
    [1] => Ferrari
    [2] => Mustang
)
Array
(
    [Keira Knightley] => 37
    [Mads Mikkelsen] => 56
    [Keanu Reeves] => 58
)
