split a string into links using the comma

this is a common function for some field data, lets say you have a string like this.

category one, category two, another category in one field or string

but i want it to display like this

category one, category two, another category

How can i do this consistantly based on the comma?

I think the best way (or at least one easy way) to do this would be to use the explode function in php. As the explode function takes one (or more) character in the string and then splits the string into an array.

PHP - Explode Function

explode(string $separator, string $string, int $limit = PHP_INT_MAX): array

then once its an array we can loop through each element and add this to the format that we require.

also you can remove the trailing comma from the last item with

PHP

$cats_links_html = rtrim($cats_links_html,", ");

PHP

// this splits the string into an array and then loops through the array
$cats = "category one, category two, another category";
$cats_array = explode(",",$cats);
$cats_html = "";
foreach ($cats_array as $cat_key => $cat_value) {
	$cats_html .= "\$cat_key: $cat_key = \$cat_value: $cat_value <br>";
}
echo $cats_html;

// now we can add the links
// also added a trim and urlencode and htmlentities there to make sure we dont have any excess spaces or html breaking / urlbreaking characters in there
$cats_links_html = "";
foreach ($cats_array as $cat_key => $cat_value) {
	$cat_value_urlenc = urlencode(trim($cat_value));
	$cat_value_html_safe = htmlentities($cat_value);
	$cats_links_html .= "<a href='#$cat_value_urlenc'>$cat_value_html_safe</a>, ";
}
echo $cats_links_html;
$cat_key: 0 = $cat_value: category one
$cat_key: 1 = $cat_value: category two
$cat_key: 2 = $cat_value: another category
category one, category two, another category

In this case my anchor this week becomes driving almost 2hrs outside of Atlanta to one of my favorite hard core gyms in the world.. MetroFlex aka The Dungeon. The gym owners turn the heat way up so it becomes a fun sweat box and the gym members just watch from afar and leave me alone. I happily drive myself long distances to find MY ANCHOR. Our anchor allows us to have balance, focus and be as productive as possible. And if you're in the middle of a heavy set and your headphones start to fall off your head, like mine did here.. well.. f*ck the headphones. Let em break and fall. You can always get a new pair, but the iron ain't ever gonna lift itself.
