本文实例讲述了Yii2针对指定url的生成及图片等的引入方法。分享给大家供大家参考，具体如下：

// /index?r=site/index echo Url::to(['site/index']); // /index?r=site/index&src=ref1#name echo Url::to(['site/index', 'src' => 'ref1', '#' => 'name']); // the currently requested URL echo Url::to(); // /images/logo.gif echo Url::to('@web/images/logo.gif'); // images/logo.gif echo Url::to('images/logo.gif'); // http://www.example.com/images/logo.gif echo Url::to('@web/images/logo.gif', true); // https://www.example.com/images/logo.gif echo Url::to('@web/images/logo.gif', 'https'); // /index?r=site/index echo Url::toRoute('site/index'); // /index?r=site/index&src=ref1#name echo Url::toRoute(['site/index', 'src' => 'ref1', '#' => 'name']); // http://www.example.com/index.php?r=site/index echo Url::toRoute('site/index', true); // https://www.example.com/index.php?r=site/index echo Url::toRoute('site/index', 'https'); echo Yii::$app->urlManager->createUrl('site/index')

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
