    It tells you that the Object class no longer exists and to use BaseObject instead.

    At the time I downgraded back to version 7.1 because I had read that there were problems with certain things in yii2 framework due to certain php changes (now object is a reserved word of the language → https://www.yiiframework.com/doc /api/2.0/yii-base-object )

    You'll need to manually fix all classes that inherit from yii\base\Objectand should now inherit from yii\base\BaseObject.

    Ideally, for this process you should follow the official update notes: https://github.com/yiisoft/yii2/blob/2.0.13/framework/UPGRADE.md#upgrade-from-yii-2012

  2. Since in php version 7.2.3 Object is a reserved word, you need to rename the file and the classes that extend that file.

    • mv vendor/yiisoft/yii2/base/Object.php vendor/yiisoft/yii2/base/BaseObject.php. to rename the file.
    • find ./vendor/yiisoft/ -type f -exec sed -i 's/class Object/class BaseObject/g' {} +. to rename the class.
    • find ./vendor/yiisoft/ -type f -exec sed -i 's/extends Object/extends BaseObject/g' {} +. to rename it in classes that extend from it.
    • find ./vendor/yiisoft/ -type f -exec sed -i 's/yii\\base\\Object/yii\\base\\BaseObject/g' {} +. modify the routes associated with the class.
    • find ./vendor/yiisoft/ -type f -exec sed -i 's/\/base\/Object.php/\/base\/BaseObject.php/g' {} +i. edit the path to the file in the classes.php file
