PHP CURL not loading in WAMP after upgrading PHP from 5.3.4 to 5.3.22
Either there are some typos in your question or you have done a few things wrong.
The new PHP should have gone into \wamp\bin\php\php5.3.22updated php5ts.dll and php5isapi.dll in Apache\bin with the new ones This is done by Switching versions in WAMP, you dont do it manually
updated Windows PATH to point to php5.3.22 folder instead of php5.3.4 There is no need to put PHP on the PATH, in fact it reduces the ability of WAMPServer to switch between various versions of PHP.
