阅读更多关于 Yii import or include

问题 I encountered a problem about importing php files. Why this works: include( Yii::getPathOfAlias( 'ext.payu.payU').'.php' ); but that don't: Yii::import( 'ext.payu.payU'); ? file payU.php: include_once( dirname(__FILE__) . "/sdk/openpayu.php"); //this is a valid path class payU{ } 回答1: Try to do Yii::import('ext.payu.payU', true) because default one-parameter Yii::import() function call means: hey, just add this path to the known aliases list and do not require() it now and you have to do new

阅读更多关于 How to do a bulk database insert in Yii2?

问题 I'm wondering how you go about doing a bulk database INSERT in Yii2 ?
