Php 任何异常的自定义错误处理程序

问题是我是根据这个主题来做的，但当我在控制器中引发异常（抛出新异常（“错误”）；）时，我不会路由到我的自定义错误控制器并使用系统默认值。如何处理此类异常？

您必须使用Yii自己的异常类之一：

ceException

、

cdbeException

或

CHttpException

。从您提供的链接：

如果mysql出现异常，请按以下方式运行查询

$insertCommand = $model->getCommandBuilder()->createSqlCommand($sql,$baseParams+$relParams);
try {
        $insertCommand->execute();
} catch(CDbException $e) {
        // Here's a way to get to the error code for the statement in question.
        // These codes are standardized ANSI SQL "SQLSTATE" error codes.
        $sqlErrorCode = $insertCommand->pdoStatement->errorCode();
        // And to get to the class part of it, simple grab the two first characters.
        // The class should be the same regardless of DB vendor, while the rest of the code can differ.
        // For example one particular error was reported by PostgreSQL as 23505 but MySQL only said 23000.
        $sqlErrorCodeClass = substr($sqlErrorCode, 0, 2);
}

我知道这种情况，但如果从mysql抛出异常（例如错误的查询或类似的smth）？并且对于每个查询，我必须编写try-catch？

$insertCommand = $model->getCommandBuilder()->createSqlCommand($sql,$baseParams+$relParams);
try {
        $insertCommand->execute();
} catch(CDbException $e) {
        // Here's a way to get to the error code for the statement in question.
        // These codes are standardized ANSI SQL "SQLSTATE" error codes.
        $sqlErrorCode = $insertCommand->pdoStatement->errorCode();
        // And to get to the class part of it, simple grab the two first characters.
        // The class should be the same regardless of DB vendor, while the rest of the code can differ.
        // For example one particular error was reported by PostgreSQL as 23505 but MySQL only said 23000.
        $sqlErrorCodeClass = substr($sqlErrorCode, 0, 2);
}
