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

    \$\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\$
