One-line Description:Set or get the reporting mode of MySQLi driver

mysqli_driver::$report_mode() is a static property that sets or gets the reporting mode of the MySQLi driver.

Reporting mode determines how MySQLi drivers report and handle errors when they encounter them. It can accept the following constants as parameters:

  • MYSQLI_REPORT_OFF: Disable error reporting and the driver will not report any errors.
  • MYSQLI_REPORT_ERROR: Only errors are reported, the driver will only report errors without interrupting script execution.
  • MYSQLI_REPORT_STRICT: Report an error and interrupt the execution of the script. The driver will report the error and throw a mysqli_sql_exception exception.

Example:

 // 设置报告模式为报告错误并中断脚本的执行mysqli_report(MYSQLI_REPORT_STRICT); // 创建MySQLi对象$mysqli = new mysqli("localhost", "username", "password", "database"); try { // 进行数据库操作$result = $mysqli->query("SELECT * FROM users"); // ... } catch (mysqli_sql_exception $e) { // 捕获并处理异常echo "发生错误:" . $e->getMessage(); }

In the example above, we first set the reporting mode to MYSQLI_REPORT_STRICT using the mysqli_report() function, which means that when an error occurs, the driver will report the error and interrupt the execution of the script. We then create a MySQLi object and perform database operations in the try-catch block. If any error occurs, the driver will throw a mysqli_sql_exception exception, which we can use the catch block to catch and handle. In this example, we simply output the error message to the screen, and you can handle it appropriately according to the actual needs.
