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
