wamp server apache doesn't contain php.ini file

Question

I want to uncomment curl in php.ini file of apache and php so I follow this steps.

1. Close WAMP (if running)
2. Navigate to WAMP\bin\php(your version of php)\
3. edit php.ini
4. Search for curl, uncomment extension=php_curl.dll
5. Navigate to WAMP\bin\Apache(your version of apache)\bin\
6. edit php.ini
7. Search for curl, uncomment extension=php_curl.dll 8 ) Save both
8. Restart WAMP

Upto step no 4 I have done. But I can't find php.ini file in apache\bin. Thanks in advance.
