PHP statement block time-consuming performance test

$t = Microtime (true);
.............................
Echo Microtime (True)-$t;

1 See how long it takes to get the final response from the portal file to the page, using Microtime (), such as Test CI:

1. $t = Microtime (true);
2. require_once BasePath . ' Core/codeigniter ' . EXT ;
3. Echo Microtime (true) - $t ;

2 View the number of files that the framework runs by default loaded:

1. Get_included_files ()

3 View the memory used by the framework:

1. Memory_get_usage ()

4 viewing function definitions, as well as constants, etc.

1. $funs = get_defined_functions ();
2. Get_defined_constants ()
3. Var_dump ($funs[' user ']);

Of course, the premise is that your controller does not have any logic processing, now think of so much.
