yii2:引用项目外的文件或类
以项目:frontend为例,文件目录如下:
frontend/
frontend/controllers
frontend/views
frontend/runtime
......
other/
other/phpexcel/
......
在frontend/controllers/IndexController.php方法中:actionIndex中,引用 PHPExcel类:
$excelpath = dirname(Yii::$app->basePath).DIRECTORY_SEPARATOR.'weixin'.DIRECTORY_SEPARATOR.'phpexcel'.DIRECTORY_SEPARATOR; include_once $excelpath . 'PHPExcel.php'; include_once $excelpath . 'PHPExcel'.DIRECTORY_SEPARATOR.'IOFactory.php'; $excel = new PHPExcel();
以上是正确引用,如果是require_once dirname(dirname(dirname(__FILE__))).'/other/phpexcel/PHPExcel.php';这样引用,是报错,找不到类:
