This may seem to be nit picking but I noted the print_r on the array to actually render browser output and within a heading tag.

The heading tag use is debatable but as a heading probably ought not have list items in that manner I would have probably thought to output a floated ul li construct either below the heading or run inline to the heading and as such you wouldn’t need to implode the array but simply do a while loop on it?

something like:
`
while (list(, $value) = each($profileTagFull)): ?>

`
that might also cut down the need for both explode/implode ?
