You don't encode the query string, just the path.<br>

<div>@URL: Actually I am maintaining the module feedapi
imagegrabber,
which downloads images from external websites. Now sometimes the url I
parse has spaces, so I am unable to decide whether or not to
percentage encode the URL, because percentage encoding will make this
URL valid but will break the following URL:<br>
<a moz-do-not-send="true"
href="http://www.google.com/search?q=hello" target="_blank">http://www.google.com/search?q=hello</a></div>
<div>by converting it to </div>
<div><a moz-do-not-send="true"
href="http://www.google.com/search?q%3Dhello" target="_blank">http://www.google.com/search?q%3Dhello</a></div>
</div>

</div>
"q=hello" is a query string, not strictly part of the path. I would
strip the url to its component parts (parse_url) and encode the path,
then re-append the query string.<br>
