php urlencode encodes wrong?

Question

If I try to encode the url

http://herthabsc.de/index.php?id=3631&tx_ttnews[tt_news]=13144&cHash=9ef2e9ee006fb16188ebf764232a0ba9 

with urlencode() or http_build_query() it gives me the result

http%3A%2F%2Fherthabsc.de%2Findex.php%3Fid%3D3631%26%23038%3Btx_ttnews%5Btt_news%5D%3D13144%26%23038%3BcHash%3D9ef2e9ee006fb16188ebf764232a0ba9

But that's not what it should be. Is there a known bug? Or problems in use with wordpress?

Answer 1

You've double encoded the URL. Running urldecode() on your output string is giving me the following: http://herthabsc.de/index.php?id=3631&tx_ttnews[tt_news]=13144&cHash=9ef2e9ee006fb16188ebf764232a0ba9

EDIT: try the following

urlencode(html_entity_decode('http://herthabsc.de/index.php?id=3631&tx_ttnews[tt_news]=13144&cHash=9ef2e9ee006fb16188ebf764232a0ba9'));
