PHP explode array then loop through values and output to variable

Question

The string I am trying to split is $item[\'category_names\'] which for example contains Hair, Fashion, News

I currently have the following

Answer 1

In your code you are overwritting the $categories variable in each iteration. The correct code would look like:

$categories = '';
$cats = explode(",", $item['category_names']);
foreach($cats as $cat) {
    $cat = trim($cat);
    $categories .= "" . $cat . "\n";
}

update: as @Nanne suggested, explode only on ','
