Separate text

Lo,

I have a variable $groups. I can contain a single number like $groups=1. But
It also can contain more numbers like $groups=1,4,3. I need to separate the
numbers and put them in a kind off array.
Something like:
$groups[1] = 1
$groups[2] = 4
$groups[3] = 3

Anybody an idea ?

I wouldn't make a exception if there's only one number, just always use
an array.
$groups = array(1); // first example
$groups = array(1, 4, 3); // second example

But I don't really get your problem?

Use the explode() function <http://www.php.net/explode>

<?
$groups ='1,4,3';
$groups_ary = explode(',',$groups);
print_r($groups);
?>
