No connection could be made because the target machine actively refused it (PHP / WAMP)

1. Go to C:\wamp\bin\mysql\mysql[your-version]\data
2. Copy and save "ib_logfile0" and "ib_logfile1" anywhere else.
3. delete "ib_logfile0" and ib_logfile1

Did the trick for me. hope it works for you too.

Its working fine. But we will have to stop apache and mysql, We need to quit xampp and then delete file. when deleted successfully. now start xampp it will work properly..

Just Go to your Control-panel and start Apache & MySQL Services.

You might need:

• In wamp\bin\mysql\mysqlX.X.XX\my.ini find these lines:

  [client] ... port = 3308 ... [wampmysqld64] ... port = 3308

As you see, the port number is 3308. You should :

• use that port in applications, like WordPress: define('DB_HOST', 'localhost:3308')

or

• change it globally in wamp\bin\apache\apache2.X.XXX\bin\php.ini change mysqli.default_port = ... to 3308
