Is MAMP relatively similar to XAMPP?
MAMP stands for Mac, Apache, MySQL, PHP
It is an adaptation of the phrase "LAMP stack" which is Linux, Apache, MySQL, PHP.
OS X has Apache and PHP built in. To turn on Apache, check Web Sharing in the Sharing panel of System Preferences.
To turn on PHP, uncomment a line in the file /etc/apache2/httpd.conf
Change: #LoadModule php5_module libexec/apache2/libphp5.so
To: LoadModule php5_module libexec/apache2/libphp5.so
For MySQL, install the package manager Homebrewhttp://mxcl.github.com/homebrew/, and then at the terminal type:
brew install mysql
It's that easy!
