How to separate array by comma but don't want last comma

Question

I want want to show an album's artists separated by comma and as a link. Artist's names are saved in array. Code will explain more.

    <?php
    $Artist_Name = array("artist1", "artist2","artist3");
    ?>
    <p class="style18"><b>Artists</b>: <span class="style24">
    <?php
    foreach ($Artist_Name as $_value) {
    $Value_new = str_replace(' ', '-', $_value);
    ?>
    <a href= "<?=BASE_PATH?>artist/<?=$Value_new?>"><?=$_value?></a>,

I'm getting the following result.

artist1, artist2, artist3,

I just want to kill that last comma and. Space. Thanks in advance. Any help would be great :)

Use implode(', ', $Artist_Name) (see implode for details)

Update

For more complex cases an array_map can be used for per-element processing:

$Artist_Name = array("artist1", "artist2","artist3");
$artist_links = array_map(
    function($value) {
        return '<a href="/' . $value . '">' . $value . '</a>';
    },
    $Artist_Name
);
echo implode(', ', $artist_links);

I want different link for different artist. This will convert array in string. – Pradeep Apr 09 '17 at 08:14
This seems promising – Wouter Vanherck Apr 09 '17 at 08:22

This question was asked here and here. However, there are a few ways to do it, for example:

$output = rtrim($string, ',');

EDIT: Having read the comment on this answer it's clear that you don't want to convert to a string. Therefore you can use a counter in your foreach and check when the last one is coming up. When it is, just don't add a ,. Hopefully this helps

In order to remove last comma from a string, you can use code below

$lastCommaRemoved = rtrim($Value_new, ',');

UPDATE Original code has many errors, here is fixed one

    <?php
$Artist_Name = array("artist1", "artist2","artist3");
?>
<p class="style18"><b>Artists</b>:
<?php
foreach ($Artist_Name as $_value) {
$Value_new = str_replace(' ', '-', $_value);
    echo '<span class="style24"><a href= "'.BASE_PATH.'artist/'.$Value_new.'">'.$_value.'</a></span>';
}
?>

I should also add, code below does nothing

$Value_new = str_replace(' ', '-', $_value);

Because there is no whitespace in values of $_value variable

But I'm using comma `, ` here. – Pradeep Apr 09 '17 at 08:18
Assume that artist1 is `Justin Bieber` should be `Justin-Bieber` for a seo friendly link. – Pradeep Apr 09 '17 at 09:19
@Pradeep good point :) you are right, then code above should do the thing, did you try it? – Оzgur Apr 09 '17 at 09:32
