thank you.

oh, , extensions:

and also, output of php -me

in wamp server, if running command line using php cli.

the php cli uses different php.ini file used when php runs in apache.

edit c:\wamp\bin\php\php5.x.y\php.ini 

and uncomment php_sockets extension line , other extensions may need when running php cli.
