creating url from number in string

robsgaming

Lets say I have a string $theNumbers = "5,7,9,11";

How can I get PHP to recognize each number before a comma, strip it out, and display that number as a url.

For instance if theNumbers had the value of 5,7,9,11 like above the following URLs would be echoed out:

$theNumbers isn't always going to be the same values or the same number of values.

In another instance, for example, $theNumbers = "1,2,3";

Again, I would need PHP to echo out URLs for the numbers in that value.

Any help is greatly appreciated. Thanks!

One thought might be to use explode on the comma and then a for loop:

$sNum = '1,2,10,20';
$aList = explode(',', $sNum);
for($a = 0; $a < count($aList); $a++)
  echo '<a href="whatever.php?number=' . $aList[$a] . '">Go ' . $aList[$a] . '</a>';

Or something like that. I'm pretty sure there's a way to do this with regular expressions...

Thanks a ton! This is going to work exactly the way I wanted it to. If it wasn't for this place, I don't know where I'd turn for help. Thanks again!
