효과에 대한 PHP 오류 처리 팁

// 开发环境
error_reporting(E_ALL);
ini_set('display_errors', 'On');

// 生产环境
ini_set('display_errors', 'Off');

function customErrorHandler($errno, $errstr, $errfile, $errline) {
    // 根据错误类型进行相应的处理操作
    switch ($errno) {
        case E_NOTICE:
        case E_USER_NOTICE:
            echo "Notice: $errstr in $errfile on line $errline";
            break;
        case E_WARNING:
        case E_USER_WARNING:
            echo "Warning: $errstr in $errfile on line $errline";
            break;
        case E_ERROR:
        case E_USER_ERROR:
            echo "Error: $errstr in $errfile on line $errline";
            break;
        default:
            echo "Unknown error: $errstr in $errfile on line $errline";
            break;
    }
}

// 设置自定义错误处理函数
set_error_handler("customErrorHandler");

function divide($numerator, $denominator) {
    if ($denominator === 0) {
        throw new Exception("Division by zero");
    }

    return $numerator / $denominator;
}

try {
    echo divide(6, 3); // 输出 2
    echo divide(3, 0); // 抛出异常
} catch (Exception $e) {
    echo "Exception: " . $e->getMessage();
}

function customErrorHandler($errno, $errstr, $errfile, $errline) {
    // 将错误信息写入日志文件
    error_log("[$errno] $errstr in $errfile on line $errline", 3, "error.log");
}

// 设置自定义错误处理函数
set_error_handler("customErrorHandler");
