Step-by-Step learning PHP

began to learn PHP, using the WebMatrix built local server (this is the simplest, but also got long time).

WebMatrix is really simple enough to say, just to create a new empty site, and then you can open the inside. Note that the runtime may return 404, this is due to the main station does not have a default page, the default page is entered under the Site settings, enter the desired default page.

Officially started PHP.

PHP scripts start with <?php and?> end.

The variable before all to add the dollar sign (and kinda greedy money): $ (Chinese input method turned into a ￥)

Note that the variables in PHP are also divided into global variables and local variables, it is easy to mix with C is that in the function can not use the global assignment after the variable.

To use global variables inside a function, add the GLOBALS keyword
