Running Etherpad on PHP on Apache

Etherpad does not use PHP or Apache.

Etherpad uses Javascript in NodeJS. You should ask your web host if they support NodeJS and if they have a guide for you to get started deploying NodeJS apps to their hosting.

Here are some services that can provide web/Node hosting for you to test/play with:
