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
