Unable to interface Arduino uno o/p on localhost

I am new user of arduino uno,but now i am getting arduino o/p on Arduino IDE,what i want to do is get that output on locally hosted website i.e coded on php.....i would appreciate if any expert can help me out here

but now i am getting arduino o/p on Arduino IDE

That seems highly unlikely. On the Serial Monitor, perhaps, but not on the IDE.

what i want to do is get that output on locally hosted website i.e coded on php

That does not make sense.

PHP is a scripting language that could read date from somewhere. A different application, listening to the serial port, could write the data where the PHP script wants to read from.
