Sorry, I didn't read d) right (NOT Methyl), here is teh new regex : /(\b#SearchTermHere#(\w+)?)/i The code sample is the same, replace regex, of course . Output should be : <b>ethyl</b> Lorem <b>Ethyl</b> ipsum MeThYl dolor <b>Ethylene</b> sit Cheers Puiu Hrenciuc wrote:

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 C.R.Vegelin wrote:

For example, for all words starting with "ethyl": a) replace "ethyl" by "<b>ethyl</b>" b) replace "Ethyl" by "<b>Ethyl</b>" c) replace "ethylene" by "<b>ethylene</b>" d) but not "methyl" by "<b>methyl</b>" Now I use: $patterns[0] = "/ethyl/"; $replacements[0] = "<b>ethyl</b>"; $text = preg_replace($patterns, $replacements, $text); This works for a) and c), but not for b) and d). Any idea how to do this ? TIA, Cor

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 ? Cor

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

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 />"; ?> Regards, Cor
