In my apache error.log I have the following line: PHP Warning: PHP Startup: Unable to load dynamic library 'ext\php_curl.dll' - The specified procedure could not be found.\r\n in Unknown on line 0
However I have checked my PATH variable and the PHP directory is listed, the ext folder is set correctly and php_curl.dll exists in the folder.
I have reinstalled vc++ redistributes to ensure that there are no issues there.
During my checking I have found that all of the following ddl's are present when opening them from run (to test they can be found from the PATH variable):
- ws2_32.dll
- wldap32.dll
- php7ts.dll
- libeay32.dll
- libssh2.dll
- nghttp2.dll
- ssleay32.dll
- normaliz.dll
- kernel32.dll
- vcruntime140.dll
- api-ms-win-crt-stdio-l1-1-0.dll
- api-ms-win-crt-string-l1-1-0.dll
- api-ms-win-crt-heap-l1-1-0.dll
- api-ms-win-crt-convert-l1-1-0.dll
- api-ms-win-crt-filesystem-l1-1-0.dll
- api-ms-win-crt-runtime-l1-1-0.dll
- api-ms-win-crt-utility-l1-1-0.dll
- api-ms-win-crt-time-l1-1-0.dll
- api-ms-win-crt-environment-l1-1-0.dll
I am unsure of what dependencies that php_curl could have, if you could provide any suggestions then this would be greatly appreciated.

1This answer provided extra clue that other answers to this issue didn't have: nghttp2.dll needed to be included, particularly with PHP 7.1. – sam452 – 2018-04-08T03:22:12.817
