beginProfile() public static method Marks the beginning of a code block for profiling. This has to be matched with a call to endProfile() with the same category name. The begin- and end- calls must also be properly nested. For example, \Yii::beginProfile('block1'); // some code to be profiled \Yii::beginProfile('block2'); // some other code to be profiled \Yii::endProfile('block2'); \Yii::endProfile('block1'); See also endProfile(). public static void beginProfile ( $token, $

$classMap public static property Class map used by the Yii autoloading mechanism. The array keys are the class names (without leading backslashes), and the array values are the corresponding class file paths (or path aliases). This property mainly affects how autoload() works. See also autoload(). public static array $classMap = []
