php - preg_replace add links around words starting with some-part-of-a-word -

i've got preg_replace in php correctly replaces every word starting 'exploit' links:

preg_replace('#[\b]?(exploit([^ ]*))[\b]?#', '<a>$1</a>', 'my exploits exploitable.');

i this:

my <a>exploits</a> <a>exploitable.</a>

which half wrong, fullstop should not linked on second word. know need replace above part [^ ] [^\b] doesn't work.

i know can i.e [^ .] work on words ending space , fullstops, not commas example.

\b(exploit[a-za-z]*) should trick.
