Simplify array to string

[Banjo]

Hello all,

I have an array like this:

PHP Code:

$people = array('Alan', 'Steve', 'John', 'Darren'); 


I was just wondering how I would be able to format that so it looked like this:

"Alan, Steve, John and Darren"

or if the array was this

PHP Code:

$people = array('Alan', 'Steve'); 


it would output

"Alan and Steve"


So I wrote some code that would do this which is this:

PHP Code:

<?php

$people = array('Alan', 'Steve', 'John', 'Darren');

$final_string = '';

for($i=0; $i < count($people); ++$i)
{
    if($i === count($people) - 1)
    {
        $final_string .= " and " $people[$i];
    }
    else 
    {
        if($i === 0)
        {
            $final_string .= $people[$i];
        }
        else
        {
            $final_string .= ", " . $people[$i];
        }
    }
}

?>

I'm just wondering if there is a better way to do this. Any help is appreciated, thank you for your time

PHP Code:


function joinNames(array $aNames)
{
    $sResult = array_pop($aNames);
    if (!empty($aNames))
    {
        $sResult = implode(', ', $aNames) . ' and ' . $sResult;
    }
    return $sResult;
}

print joinNames($people);
