Of course, these are based on window In the following direction, it is divided into two paths, the ancestor app_PATH and think_PATH</span><span>// Second: What we can record is </span><span>// As a framework program, it needs to be able to record the execution time and memory of the script consumption, so I turned on mirctime and memory_get_usage without hesitation</span><span>// This moment serves as the starting point of time and memory. </span><span>// Third: What deserves our attention is: </span><span>// Use const and define to define system constants, but the feeling is that they must be immutable. Using const</span><span>// means that this is completely solidified Damn, define allows users to modify it when creating their own app. Before the system defines it, it will check whether it is defined. </span><span>// There is no way to redefine const </span><span>// Summary There is basically no difference. The only difference between these two is usage, which is a difference in compilation! </span><span>// Fourth: System predefined variables [GPC] and text data stream </span><span>// Basically it can be said to be non-escaping processing, is there something like addsalshe? </span><span>// Fifth: Interpret php and The communication method of the web server is cgi</span><span>// Determined the operating system</span><span>// Determined whether the command line tool runs away from the server</span><span>// Sixth: Regarding the inconsistency in the definitions of ROOT and _FILE_ files, reworked Multi-platform definition enhances platform portability. </span><span>// In short: it standardizes the definition and its cross-platform features! </span><span>// Next we will explain these public functions with functions.php 20151205</span><span>/*** Instantiate multi-layer controller format: [resource://][module/]controller
