mysql php implode row for links?

Not sure if there a way of doing this, but I can insert multiple categories into MYSQL, using :

GetSQLValueString(implode($_POST['r_category'],", "), "text"),

So then when I echo:

<?php echo $row_Recordset1['r_category']; ?>

It is fine, like this: Cat 1, Cat 2, Cat 3

I am trying to find a way to link each category for easy navigation purposes!!

Like this:

<a href="/page/results.php?r_category=<?php echo $row_Recordset1['r_category']; ?>"><?php echo $row_Recordset1['r_category']; ?></a>

This works great for One开发者_开发知识库 Cat, but if I have multiple Cats, then it is one big link.... not what I want.

I need to use implode or explode, but not sure how ? Thanks in advance!!!

This is what I would love:

Cat 1, Cat 2, Cat 3 (these are all separated links pulling from one row!)

If $row_Recordset1['r_category'] is the string "Cat 1, Cat 2, Cat 3", then you can explode that into an array like this:

$arr = explode(",", $row_Recordset1['r_category']);

then step through your array to create the links:

$links = array();
foreach ($arr as $value)
{
    $links[] = "<a href='/page/results.php?r_category=". trim($value) ."'>". trim($value) ."</a>";
}
$links_str = implode(", ", $links);
echo $links_str;
