This is the php code used by uchome. when you are learning programming, you can see some mature cms systems at that time, provided that you are familiar with the program, otherwise, the study will be dispelled. UCHOME code is still very good. learn it!

The code is as follows:


/**
* Define constants
*/
@ Define ('in _ UCHOME ', TRUE); // It is said that it can prevent illegal file inclusion
Define ('x _ VER ', '1. 2'); // Uchome version
Define ('x _ release', '000000'); // RELEASE date
Define ('d _ BUG, '0'); // whether to enable the debugging function, 0: Disabled, 1: enabled
// Set the error report level based on whether debugging is enabled
D_BUG? Error_reporting (7): error_reporting (0 );
// Initialize some global variables
$ _ SGLOBAL =$ _ SCONFIG =$ _ SBLOCK =$ _ TPL =$ _ SCOOKIE = $ space = array ();
// Define the program directory constant
Define ('s _ ROOT ', dirname (_ FILE _). DIRECTORY_SEPARATOR );
// Get the time, mainly used to output the program running time
$ Mtime = explode ('', microtime ());
$ _ SGLOBAL ['timestamp'] = $ mtime [1];
