Question

I am working on incorperating the jplayer html5 audio playlist

I’m using a foreach to generate the script element for each playlist item.
Everything is working as expected, Except I’ve included the comma in the loop, but I need a way to write the comma as separator except for last item.

here is what I’ve got so far to generate jplayer playlist.

<?php foreach( $songs as $song ): if( !empty($song) ): ?>{

        title:"Each Song Title",

        mp3:"Each song mp3 url"

    },<?php endif; endforeach; ?>

which gives me

    {

        title:"Partir",

        mp3:"http://www.jplayer.org/audio/mp3/Miaow-09-Partir.mp3"

    },

    {

        title:"Thin Ice",

        mp3:"http://www.jplayer.org/audio/mp3/Miaow-10-Thin-ice.mp3"

    },
    {

        title:"Ice man",

        mp3:"http://www.jplayer.org/audio/mp3/Miaow-10-Thin-ice.mp3"

    },

This is my desired result

    {

        title:"Partir",

        mp3:"http://www.jplayer.org/audio/mp3/Miaow-09-Partir.mp3"

    },

    {

        title:"Thin Ice",

        mp3:"http://www.jplayer.org/audio/mp3/Miaow-10-Thin-ice.mp3"

    },
    {

        title:"Ice man",

        mp3:"http://www.jplayer.org/audio/mp3/Miaow-10-Thin-ice.mp3"

    }

Can anyone point me in the right direction?

Answer 1

I use next() for it:

$arr = array(1,2,3,4,5,6,7);
$copy = $arr;
foreach ($arr as $val) {
    echo $val;
    if (next($copy )) {
        echo ','; // Add comma for all elements instead of last
    }
}
