If you have your Arduino on tcp/ip your answer can be found in O'Reilly's Arduino Cookbook: Recipe 15-4. As Sourcery mentioned you need to make a new page on the PHP side that spits out just the data you are looking for and then use a web client on the Arduino side to download that data.

If you don't have your Arduino on the network then you have to stick the data over the serial line. One way would be to bake it into your source and recompile/reburn the Arduino. A smaller hammer would be to build-in something to your Arduino sketch that can deal with getting the data via USB serial and have a shim on the computer side to pull the data from PHP and send it to the Arduino. Serial communication with Arduino and ProcessingSerial communication with Arduino and Processing shows something similar where he is running Processing on the computer which is passing data to the Arduino.
