install curl extension fail
<p>I try to install php curl extension in my win xp environment but failed.
To follow the manual ,I have copied libeay32.dll and ssleay32.dll into %systemroot%/system32 dir ,the ';' in front of 'extension=php_curl.dll' also has been opened 
but in the test function phpinfo(), there is still not any clues </p>

<p>but the other extensions like php_gd2.dll,php_pdo.dll can be opened or closed without any problems</p>

<p>any help would be appreciated</p>
