Hi,
Here's what you need:
RegEx:
/((\w+)?#SearchTermHere#(\w+)?)/i
Of course, replace your #SearchTermHere# with what you need,
i.e. /((\w+)?ethyl(\w+)?)/i
Code sample:
$_textToHighlight='ethyl Lorem Ethyl ipsum MeThYl dolor Ethylene sit';
$_search='/((\w+)?ethyl(\w+)?)/i';
$_replace='<b>\\1</b>';
$_highlightedText=preg_replace($_search,$_replace,$_textToHighlight);
This should output:
<b>ethyl</b> Lorem <b>Ethyl</b> ipsum <b>MeThYl</b> dolor
<b>Ethylene</b> sit
Hope it helps,
PuYa

thats odd because the regex passes when I test it with this online tool:

Thanks Deniz,
I tried pattern /^ethyl/i but this does not highlight anything.
I also tried pattern /ethyl/i and this highlights all, but
also methyl ...
Any suggestion ?

Hi Deniz,
I tried the referred regex tool as well,
and I get Bad Result for /^ethyl/i
and Good Result for /ethyl/i
