If the current address bar has a query character and is a number, the condition is set.
Query character: www.baidu.com/index.php?aaa=bbb aaa=bbb is the query character
If the condition is established, the home is assigned to $_env[' Curapp ']; $_env can be understood as a hyper-global array similar to $_get. Here the $_env[' Curapp ' can be understood as the selected entry file.
and passes an array to $_get, the first member of the array specifies the controller name, and the second member formulates a parameter called UID, which is the user ID.

If the conditions here, 127 lines of the IF statement must be false, the following a large number of code is not executed, has jumped to 137 rows, directly loading the portal file.


If the first if statement is False


Cache_domain.php is a system-generated configuration file. The $domain array is declared in the cache_domain.php file.

If $_env[' domain ' is empty, set the currently selected app to Forum (forums), then skip to line 137.
If $_env[' domain ' is not empty

25: Split the current host domain name into an array by the. Number.

27: The acquired domain name is intercepted from the position of the first. For example, www.baidu.com, after the cut, baidu.com

28: If [' Domain '] [' app '] is not empty and is an array, and the domain name currently being accessed is also an item of its array value. The

30: Find the key for the current domain name in the app array as the selected app. For example, the currently accessed domain name is www.baidu.com and found in the app array:

75: Get the domain name prefix
76: Get root domain Name
77: Load Frame Entry file

This string of code can be seen as an initialization operation. These are the properties of the Discuz_application class.

85: This line of code will query the database through the Table_common_domain class to find the application type of the root domain binding. Fetch_by_domain_domainroot




If the app type is home, how about if the app type is group.
