How to get CURL to work with PHP on Windows? (WAMP)

You don't have to reboot the computer, just restart the apache and the php module will read the new ini.
Did you change the correct php.ini? In case of doubt

<?php echo 'php.ini: ', get_cfg_var('cfg_file_path'); ?>

can tell you.

Is there something in the error.log of the apache that indicates that something went wrong while loading php and the php_curl.dll?

Did you start the apache as a win32 service? If you did try to start it as a console application. Error messages will show up on the console then. Or start it as a service and take a look at the error.log file and the windows event log (start, run, eventvwr.msc /s).

edit:
"The specified procedure could not be found"
You need a dll that is compatible with your php version and build. Exactly what did you install and where did you get it from?

Try this:

1. Stop WAMP completely.
2. Find your WAMP folder: C:\Path\To\WAMP\bin\Apache\ApacheVersion\bin\
3. Edit that php.ini and uncomment extension=php_curl.dll
4. Restart WAMP.

That should hopefully solve it.

*EDIT: Do the same thing @ C:\Path\To\WAMP\bin\php\PHPVersion\

This is what worked for me

"There seems to be a bug somewhere. If you are experiencing this on Win 7 64 bit then try installing apache addon version 2.2.9 and php addon version 5.3.1 and switching to those in WAMP and then activating the CURL extension. That worked for me."
