Thanks Puiu,
I tested your regex with the code below.
However, it didn't work.
Maybe I'm missing something ...
To test it, change the $pattern setting.
<?php
$term = "ethyl";
$text = "Ethylene, ethyl and methyl are different things.";
$pattern = "/(\b#" . $term . "#(\w+)?)/i";
$replacement = "<b>" . $term . "</b>";
// or: $replacement = "<b>\\1</b>";
echo "before: " . $text, "<br />";
$text = preg_replace($pattern, $replacement, $text);
echo "after: " . $text, "<br />";
echo "wanted:<br /><b>Ethyl</b>ene, <b>ethyl</b> and methyl are different
things.", "<br />";
echo "or:<br /><b>ethyl</b>ene, <b>ethyl</b> and methyl are different
things.", "<br />";
?>
