[MAC PHP]MAMP: 在Mac OSX上本地快速安装PHP+MYSQL+APACHE

Why should I use MAMP? Isn't everything already installed in OS X?

At the moment, when using OS X, only Apache 1.3.x with PHP 4.3.2 is pre-installed. PHP has to be activated by changing the configuration files. The Apache/PHP versions provided by Apple are not always up-to-date, and the Apache-PHP combination is quite slow. In addition, MySQL has to be installed manually.
With one click, and in just a few minutes MAMP will install Apache 2, current PHP 4, current PHP 5 and MySQL. Using the included eAccelerator, PHP-scripts are executed up to ten times faster compared to Apple's pre-installed Apache/PHP. When you use the MAMP programme, you can easily start and stop the server. Thus, the server does not have to be running in the background all the time, wasting precious resources. To "uninstall" MAMP, you only have to delete the MAMP directory and everything returns to the original state (MAMP does not alter anything on the "normal" OS X).
