I have an script which gets the content of webpage by cURL, Now i have to highlight some keywords in that. str_replace is not working beacuse if i replace 'a', than all will be replaced and that will create a problem.

Please can anybody help?

Personally I would only handle this on the client side, for one reason only, don't reinvent the wheel or mess around if you don't need to.

I did exactly what you are asking by utilizing a plugin for jquery:

JavaScript text higlighting jQuery plugin

http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html

What you do is basically in the <head> of your HTML create an entry like:

$('body').removeHighlight().highlight('<?php echo "text to highlight"; ?>');

Easy as pie, and don't have to tinker with anything

If you want to highlight words you can use the *preg_replace* function like that :

foreach($myKeywords as $keyword)
     $myNewCode = preg_replace("/[\\s*\\.,](".$keyword.")[\\s*\\.,]/",'<span class="highlight">${1}</span>',$myCode);

You can replace ' a ' instead of just 'a' if you want to use str_replace.
