php - Explode to array and print each element as list item - Stack Overflow

$numbers = '1,2,3';

$array =  explode(',', $numbers);

foreach ($array as $item) {
    echo "<li>$item</li>";
}

Assuming your original $set_of_numbers is simply a CSV string, something like 1,2,3,4,..., then your foreach is "mostly" ok. But your variable naming is quite bonkers, and your print-r() call uncesary:

$array = explode(',', $set_of_numbers);
foreach($array as $key => $value) {
   echo "<li>$key: $value</li>";
}

Assuming that 1,2,3,4... string, you'd get

<li>0: 1</li>
<li>1: 2</li>
<li>2: 3</li>
etc...

php - Explode each values of Array element - Stack Overflow

You can use

$result = array_map(function($val) {
    return explode(',', $val);
}, $input);

Which will result in

Array
(
    [2] => Array
        (
            [0] => 2
            [1] => 6
        )

    [3] => Array
        (
            [0] => 1
        )

    [4] => Array
        (
            [0] => 14
        )

    [5] => Array
        (
            [0] => 10
        )

    [6] => Array
        (
            [0] => 8
        )

)

This will work on PHP >= 5.3 with support for anonymous functions.

You can also do

$result = array_map('str_getcsv', $input);

This will also result in

Array
(
    [2] => Array
        (
            [0] => 2
            [1] => 6
        )

    [3] => Array
        (
            [0] => 1
        )

    [4] => Array
        (
            [0] => 14
        )

    [5] => Array
        (
            [0] => 10
        )

    [6] => Array
        (
            [0] => 8

PHP explode array then loop through values and output to variable - Stack Overflow

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 .= "<category>" . $cat . "</category>\n";
}

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

Without a for loop

$item['category_names'] = "Hair,   Fashion,   News";
$categories = "<category>".
        implode("</category>\n<category>", 
        array_map('trim', explode(",", $item['category_names']))) . 
        "</category>\n";
echo $categories;
