Fatal error - The declaration of class `Freemius_Api_WordPress` is not compatible with class `Freemius_Api_Base` from the PHP SDK

[daigo75]

🐞 bug report

Behavior: When a plugin loads the PHP SDK before the WordPress SDK, the class Freemius_Api_Base from the former is loaded automatically. When the class Freemius_Api_WordPress is loaded, it triggers a fatal error, because methods such as Freemius_Api_Base::Test() are declared as static in the PHP SDK, and dynamic in the WordPress SDK.

Examples

• Method Freemius_Api_Base::Test(): https://github.com/Freemius/freemius-php-sdk/blob/master/freemius/FreemiusBase.php#L157
• Method Freemius_Api_Base::FindClockDiff(): https://github.com/Freemius/freemius-php-sdk/blob/master/freemius/FreemiusBase.php#L170

Suggested solution The class Freemius_Api_Base in the WordPress SDK works because it doesn't declare any of the affected methods, which are implemented by class Freemius_Api_WordPress. If the class Freemius_Api_Base is supposed to be identical between the WordPress and the PHP SDK, it might be sufficient to replace the existing code with the one from the WordPress SDK.

Versions: (*)

• Freemius SDK Version: 2.4.3 to 2.5.2
• WordPress Version: 5.9 to 6.1
• PHP Version: 8.x

Plugin / Theme: (*)

• Name: Any
• Freemius ID: Any

Note The plugin itself is not relevant, in this case. As long as the PHP SDK is loaded before the WordPress SDK, the error will occur.
