    They include 2 files in a run. Think of it this way: all the files in it will definitely be combined by PHP into one big script. Each include or require creates a file and inserts its content around this script. Two

    The information you provide requires the same file that declares the Database class. This means that a large PHP generated script looks like this:

      class messageClass database// only message.php is requiredHeavy userClass database// required for user.php 

    fatal error cannot redeclare class db_sql in

    As users can see, the Database class is declared twice, which indicates an error.
    For a while, a quick fix might also be to use require ('database.php'); with:

    . replace

      require_once 'database.php'; 

    fatal error cannot redeclare class db_sql in

    How much money if this particular file was not previously included / required. If it was previously enabled / required, PHP is no longer needed.
    A much more specific and better solution IMHO would be to register a function / method of the autoloader class and also do code maintenance for the pre acceptances.

    For more information on registering an autoloader, see the documentation. If your company chooses this route, you will probably need to consider the HTML encoding of the standard class names and namespaces listed here. If you adhere to these standards, the person doesn’t need to write their own personal autoloader and can just use the generic Loader Symfony2 learning framework or any platform that subscribes to the PHP-FIG hopes (like CodeIgnitor, Zend, Pie … you name it)

    I was pretty sure I knew where to put this puzzle – in the Schema Builder project or here.

    I have this problem when I bind $ fieldConf to a property of my user model class. If I remove it, the error goes away.

     class user    table $ protected = 'user';    protected $ fieldConf = [        'Settings' => [            'has-many' => [' models  UserSetting', 'user_id']        ]    ];UserSetting class    discussed $ table = 'users_settings';    registered $ fieldConf = [        'User' => [            'owned' => ' model  user'        ]    ];

    Why Is There A Fatal PHP Error?

    fatal error cannot redeclare class db_sql in

    Many of our clients have encountered this error. Typically, this error causes the script to stop immediately.

    Basically, “PHP’s life-threatening error cannot re-declare class” means that the class name may already exist.

    Most of the time, obvious errors occur when a user develops PHP code from scratch. But WordPress blog sites also show the same error due to plugin or theme conflicts.

    1. Code Error

    PHP, although fatal HTML coding errors are fairly common. The developerand often get an error when trying to declare a class that is already available. The error message looks like this:

      Serious PHP error: class cannot be re-declared.  

    Recently one of our target markets contacted us with this error. Therefore, today we suggested that he not use the already provided classes for further coding.

    But new tutorials created by our client also contain the same error. So, we have provided below command for you to fix the problem.

      include_once "xxxx.php";  

    2. Class Error In WordPress Cannot Be Declared Again

    Usually PHP based WordPress shows our error after installing new plugins or templates. Typically WordPress displays an error message:

    When our customers contact us with an error message, our support team investigates the cause of the error.

    In most cases, the error will be the same as the class spacing in function.php, not to mention the plugin files. To fix our mistake, disable the plugin and install our latest version.
