How to install a basic Apache, PHP and MySQL development environment with Homebrew

This guide will walk you through the steps required to install a basic Apache, PHP and MySQL development environment using homebrew. Basically, all you'll need to do is copy the commands below into Terminal. Copy one block at a time.

NOTE: this guide is mirrored from Echo & Co.'s blog in case the original blog post or the website decides to go down. I've shared this guide around many times to colleagues and friends. Please give Alan Ivey (@alanthing) all of the credit for publishing this really helpful guide.

Before we begin...

We're going to need to install homebrew, a super awesome package manager for OS X. Installation instructions are available on the homebrew website.

    ///       doAsyncThings()
    ///       eventually {
    ///           /* XCTAssert goes here... */
