The PHP array_reduce() function sends the values in an array to a user-defined function, and returns a string. If the array is empty and initial is not passed, this function returns NULL.
<?php
function my_function($z1, $z2) {
return $z1 . '<br>' . $z2;
}
$a = array('Lamborghini', 'Ferrari', 'Maserati');
print_r(array_reduce($a, 'my_function'));
?>
Output
Lamborghini
Ferrari
Maserati

| my_function | Specifies the name of the function (required) |

PHP NOTES:
- When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
