Question

Given the following array:

Array
(
    [143] => Car #1
    [144] => Car #2
    [145] => Car #3
)

I am currently using this

implode(', ', array_values($car_names))

to generate a string like

Car #1, Car #2, Car #3

I would like to actually get something like

Car #1, Car #2 and Car #3

The idea would be to insert ” and “ between the two last elements of the array.

If the array happens to contain two key/value pairs (eg, user has 2 cars), there would be no commas.

Car #1 and Car #2

And if the array contains one key/value (eg, user has 1 car)

Car #1

Any suggestion how to get this done? I tried using array_splice but I’m not sure that’s the way to go (ie, inserting a new element into the array).

Thanks for helping!

I think you probably want something like this, using array_pop to get the last element off the end of the array. You can then implode the rest of the array, and add the last element in a custom fashion:

$last_value = array_pop($car_names);
$output = implode(', ', array_values($car_names));
$output .= ($output ? ' and ' : '') . $last_value;

Edit: added conditional to check if the array had only one element.
