Title: PHP compatibility & performance issue!

Seems PHP 8 is really not ready for use sadly. )o; * Thread Starter [Xandro](https://wordpress.org/support/users/sudarshankotian/) * (@sudarshankotian) * [3 years, 7 months ago](https://wordpress.org/support/topic/php-compatibility-performance-issue/#post-16074103) * Thanks for the update [@neikoloves](https://wordpress.org/support/users/neikoloves/) in fact I tried this on php 7.4 🙄 * Plugin Author [Disable Bloat](https://wordpress.org/support/users/disablebloat/) * (@disablebloat) * [3 years, 7 months ago](https://wordpress.org/support/topic/php-compatibility-performance-issue/#post-16090634) * Hello [@sudarshankotian](https://wordpress.org/support/users/sudarshankotian/) and [@neikoloves](https://wordpress.org/support/users/neikoloves/) * Thank you for using the plugin. * PHP: * The plugin is fully compatible with PHP 8.0 and 8.1. It has been fully tested with these PHP versions and you can be sure that there are no errors/warnings/ notices caused by using PHP 8.X with our plugin. We are running PHP 8.1 in our test environment and I can assure you that you won’t expect any problems caused by the upgrade to PHP 8.X. * In this case, PHP Compatibility Checker is reporting false positives, as the mentioned variables are not actually modified before the mentioned functions are called. You can read about the false positives in the [PHP Compatibility Checker readme](https://wordpress.org/plugins/php-compatibility-checker/): * > Please note that linting code is not perfect. This plugin cannot detect unused > code-paths that might be used for backwards compatibility, and thus might show > false positives. We maintain a whitelist of plugins that can cause false positives. > We are continuously working to ensure the checker provides the most accurate > results possible. * Memory usage: * After implementing the license management system in the 3.0 version of the plugin, the plugin is using more memory during activation. During the activation process, the plugin is making necessary checks which can be more memory-consuming. We are currently investigating this issue and checking if the memory usage is getting lower after the activation. We will try to fix this issue after finishing the analysis process. * Thread Starter [Xandro](https://wordpress.org/support/users/sudarshankotian/) * (@sudarshankotian) * [3 years, 7 months ago](https://wordpress.org/support/topic/php-compatibility-performance-issue/#post-16091258) * Hi, [@disablebloat](https://wordpress.org/support/users/disablebloat/) thanks for the update. Good to know that, this plugin is Php 8.1 compatible. 😉 * Plugin Author [Disable Bloat](https://wordpress.org/support/users/disablebloat/) * (@disablebloat) * [3 years, 7 months ago](https://wordpress.org/support/topic/php-compatibility-performance-issue/#post-16096569) * Sure [@sudarshankotian](https://wordpress.org/support/users/sudarshankotian/) * We will update the PHP code in the plugin so that the Checker won’t show any false positives in the future. * [neikoloves](https://wordpress.org/support/users/neikoloves/) * (@neikoloves) * [3 years, 7 months ago](https://wordpress.org/support/topic/php-compatibility-performance-issue/#post-16096619) * [@disablebloat](https://wordpress.org/support/users/disablebloat/) [@sudarshankotian](https://wordpress.org/support/users/sudarshankotian/) It’s great to know this is only a false positive. The licencing system is just a mess, not an easy one to solve I guess. Seems to be buggy at best. Thanks for the updates guys. * [diegpl](https://wordpress.org/support/users/diegpl/) * (@diegpl) * [3 years, 7 months ago](https://wordpress.org/support/topic/php-compatibility-performance-issue/#post-16145521) * [@disablebloat](https://wordpress.org/support/users/disablebloat/) for me that is the error the plugin shows, I read your answers, just posting it here bcz it is might not be the same you saw before: version_compare(): Passing null to parameter #1 ($version1) of type string is deprecated * ``` wp-content/plugins/disable-dashboard-for-woocommerce/includes/functions/disable-bloat-functions_free.php:102 version_compare() wp-content/plugins/disable-dashboard-for-woocommerce/includes/functions/disable-bloat-functions_free.php:102 Disable_WC_Bloat->includes() wp-content/plugins/disable-dashboard-for-woocommerce/disable-dashboard-for-woocommerce.php:125 Disable_WC_Bloat->__construct() wp-content/plugins/disable-dashboard-for-woocommerce/disable-dashboard-for-woocommerce.php:115 Disable_WC_Bloat::instance() wp-content/plugins/disable-dashboard-for-woocommerce/disable-dashboard-for-woocommerce.php:194 disable_woocommerce_bloat() wp-content/plugins/disable-dashboard-for-woocommerce/disable-dashboard-for-woocommerce.php:198 ``` * [@disablebloat](https://wordpress.org/support/users/disablebloat/) and about the memory issue [@sudarshankotian](https://wordpress.org/support/users/sudarshankotian/) told us about?
