I'll hold my answer as general as you asked your question:
- get a Raspberry Pi or something similar
- set up Apache2+PHP
- get a very strong relay which can switch on the AC motor and can take an input of 5V
- connect the relay input to one of the Raspberry Pi GPIO output pins
- connect the relay output to the AC motor
- write a php script which lets you toggle the connected GPIO output pin of the Raspberry Pi

3\$\begingroup\$ Don't forget that it's not safe to directly run relay from GPIO pins! Since rely has as coil, there's the inductive kick. Then there's also power consumption, so a transistor and a flyback diode would be needed for safe operation. \$\endgroup\$ Mar 4, 2013 at 9:22
