Overview

mampenv is here to help you make sure that your command line is running the same version that your MAMP Pro sites running.

Simply put a .phpversion file in the root of your folder and have the peace of mind of knowing that your PHP version on the command line matches the version MAMP Pro is running for your site. All from a code repository kept in your local .mampenv folder.

Key features:

Inspired by phpenv and rbenv
Run MAMP-supporeted PHP versions directly from the command line
Support for composer too
Use project-specific versions of MAMP's PHP installations
PEAR? PECL? Oh yes, each MAMP version of PHP already has that

How It Works

mampenv operates on the per-user directory ~/.mampenv. This directory contains shim-style scripts that take over the php and composer commands on the command line. It will make sure they are executed using the PHP version specified in your project folder's .phpversion file, if one is present. Otherwise, it will use the latest version of PHP supplied with MAMP.

Each MAMP PHP version is a stand-alone installation with its own binaries and configuration.

Installation

Basic GitHub Checkout

This will get you going with the latest version of mampenv and make it easy to fork and contribute any changes back upstream.

Check out mampenv into ~/.mampenv.

 $ cd
 $ git clone git://github.com/benallfree/mampenv.git .mampenv

Add ~/.mampenv/bin to your $PATH for access to the mampenv command-line utility.
```
 $ echo 'export PATH="$HOME/.mampenv/bin:$PATH"' >> ~/.bash_profile
```
Add mampenv init to your shell to enable shims and autocompletion.
```
 $ echo 'eval "$(mampenv init -)"' >> ~/.bash_profile
```
Restart your shell so the path changes take effect. You can now begin using mampenv.
```
 $ source ~/.bash_profile
```
If all goes well, which php should indicate a ~/.mampenv/bin/php path. which composer should say ~/.mampenv/bin/composer and which pear should say ~/.mampenv/bin/pear

Upgrading

If you've installed mampenv using the instructions above, you can upgrade your installation at any time using git.

To upgrade to the latest development version of mampenv, use git pull:

$ cd ~/.mampenv
$ git pull

Usage

Like git, the mampenv command delegates to subcommands based on its first argument. The most common subcommands are:

mampenv versions

List the local MAMP PHP versions installed.

$ mampenv versions

Anchoring your project

First, see what versions are available on yoru system.

$ mampenv versions

If you don't like any you see, visit the MAMP Pro Downloads section and download more.

Next, navigate to your project directory and create a .phpversion file.

$ cd ~/my_project
$ echo "5.5.10" > .phpversion

Now test the version.

$ which php                 <-- Should say ~/.mampenv/bin/php
$ php --version

Contributing

The mampenv source code is hosted on GitHub. It's clean, modular, and easy to understand, even if you're not a shell hacker.
