PHP: How to escape the url params and path without encoding the Scheme and Host in URL?

PHP: How to escape the URL params and path without encoding the Scheme and Host in URL:

Please notice* this url is just an example params might be named different than q and some urls might have path others might not, like the example below.

I get the url as follows:

http%3A%2F%2Fgoogle.com%2F?q=My%20Search%20Keyword

Then I should converted to the following:

http://google.com/?q=My%20Search%20Keyword

not:

http://google.com/?q=My Search Keyword

is there an easy way for doing this, other than

  1. Url decoding the whole url, via "rawurldecode"
  2. "parse_url" to split it to scheme, domain, path, query
  3. Parse the query with parse_str and escape the values only.
  4. Rebuild the query string
  5. Rebuild the url back,
  6. All the steps above require checking for empty values too.

UPDATE

In more complicated case I get the URL like this:

http://www.someUrl.com/?redirect=http%3A%2F%2Fgoogle.com%2F%3Fq%3DMy%20Search%20Keyword%26hl%3Den

Where I search for =http..... then I use this part to crawl it via Curl and get the http response code from this url, the problem is that I can't easily prepare the url which was sent ecnoded from the beginning without involving the complicated process I mentioned above.

is there an easier way of doing this ?

I came up with the following solution, it might have flaws, but might help someone else as well .. 

$url = rawurldecode('http%3A%2F%2Fgoogle.com%2F%3Fq%3DMy%20Search%20Keyword%26hl%3Den');
echo preg_replace_callback('#[^/\.\:&=\?]{1}#',
    function($str) { return rawurlencode($str[0]);}, 
    $url
);

Try this:

<?php
$rawUrl = 'http%3A%2F%2Fgoogle.com%2F?q=My%20Search%20Keyword';
$arrDec = parse_url(urldecode($rawUrl)); 
$queryEnc = parse_url($rawUrl, PHP_URL_QUERY);

$newUrl = $arrDec['scheme'] . '://' . $arrDec['host'] . '?' . $queryEnc;

print_r($newUrl);

?>

Can't you just explode on the ?, then rawurldecode the first part, then implode?

$url = "http%3A%2F%2Fgoogle.com%2F?q=My%20Search%20Keyword";
$parts = explode("?", $url);
$parts[0] = rawurldecode($parts[0]);
$url = implode("?", $parts);
