is it possible to compare two different text messages and highlight the difference in php. i mean to say that $text1="message 1" $text2="message 2" i want to compare both $text1 and $text2 for differences and highlight the differece in php.is it possible. waiting for your reply.

Untested, very crude: <?php $maxlen = max(strlen($text1), strlen($text2)); for ($i = 0; $i < $maxlen; $i++){

    if (@$text1[$i] == @$text2[$i]) echo @$text1[$i];
    else @echo "<font color=red>$text1[$i]|$text2[$i]</font>";

Would it be possible to explode both messages on " " into an array and run array_diff() and work from there? Just a thought late in the day... Edward Vermillion evermillion@doggydoo.net
