在每个类别后添加逗号

Question

this seems like a pretty straight forward question and for some reason I am having trouble figuring out how to achieve what I am looking for.

$category = $html2->find('.video_cats',0);
$category = $genre->plaintext;


<div class="video_cats">
<span>Categories:</span>
    <a href="http://www.example.com" title="Example Category" class="video_cat">House</a>   
    <a href="http://www.example.com" title="Example Category" class="video_cat">The Cat</a> 
    <a href="http://www.example.com" title="Example Category" class="video_cat">Car</a> 
    <a href="http://www.example.com" title="Example Category" class="video_cat">The Dog</a>                                                             
</div>

Currently I have a string called $category if we print the results of this string it will return the following text One Two Three Four Five I am trying to make it so that it returns the text One, Two, Three, Four, Five. Any help is greatly appreciated.

EDIT : This is the desired output Category: A Cat, Dog, A Horse, House because some of the category names have spaces in them we can't just replace the spaces with commas.

Search for the anchors rather than the DIV, then you can loop over them and make an array.

$cat_array = array():
foreach ($html2->find(".video_cat") as $cat) {
    $cat_array[] = $cat->plaintext;
}

$category = implode(', ', $cat_array);
