PHP Search Engine

add this to about line 630 just before “remove contents of javascript”

// remove custom are between <!-- hidesearch start --> and <!-- hidesearch end --> from html code
$url_data['data'] = preg_replace('#<!--\s*hidesearch start\s*-->.*<!--\s*hidesearch end\s*-->#ismU','',$url_data['data']);

<!-- hidesearch start -->

<!-- hidesearch end -->

Use this code:

<form action="search.php?iframe=true" id="searchform" method="post" target="iframesearch">
My Website: <input type="text" name="search" id="searchbox" value="test"> <input type="submit" name="go" value="Search">    
</form>
<iframe frameborder="0" name="iframesearch" id="iframesearch" src="about:blank" style="width:100%; height:500px;" scrolling="auto"></iframe>

change search.php to point to wherever your search.php is located. style as necessary.
