The PHP Web Development Community is also working on rewriting the PHP engine. This would clean things up and may improve performance. Although it may not be required to rewrite the complete engine all over again, a little refactoring would help to improve performance.
PHP is popular and there is no question about that. There are a lot of tools written using PHP, like WordPress and Drupal. WordPress has shown steady increase in usage and today is the most popular content management system across the globe. Drupal also has large user base and is popular especially for community sites.
