I am having problems with finishing a function I have made which uses PHP's preg_replace.

The function runs through text within a forum I am designing to highlight target words to the user based on their interests etc I am hoping to allow a customizable tool-tip to pop-up over the highlighted areas to give the user extra information/ links etc.

The function is highlighting the words 100% and my tooltip is displaying the way I want it atm BUT the problem I am having is getting the PHP variable $definition to output its content instead of "$definition".

The problem seems to be the method I am trying to output a variable within a String. I have exausted every way I know of doing this and would like help. I have tried using <?php echo "$definition"?>, ".$definition.", print $definition, echo $definition....

Does anyone know any way or method to get the output of $definition to populate the tooltips?

PHP Code:

function getTargetWords($fContent){

....

.... 

....



/***Definition***/

       $definition = "Definition text for inside the tooltip";



/***!!!!!!!!To be fixed to output tooltip definition not "$definition" !!!!!!!!!***/        

       $replace = '<a href="#"><span class="highlight_word">\1<span class="tooltip">$definition</span></span></a>';

                

 /*** highlight the words ***/

         $fContent = preg_replace("/\b($word)\b/i", $replace, $fContent);

....

....

....

} 

any help will be appreciated, thanks
