• How to avoid memory leaks in Symfony Commands

  • dirty Entity Manager
    Use clear() method once a while, it detaches doctrine objects that are not used any more.

    	$this->em->flush();
     	$this->em->clear();
    

  • SQL Logger, this one was the worst to find
    Every time you query database SQL Logger stores information about that.
    Normally, it’s not a problem but in commands running infinitely every KB counts.
    You can turn it off like this.

    	$this->em = $this->getContainer()->get('doctrine')->getEntityManager();
    	$this->em->getConnection()->getConfiguration()->setSQLLogger(null);
    

• Symfony requirements 检查和优化建议

    $ php bin/symfony_requirements
    
        Symfony Requirements Checker
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        > PHP is using the following php.ini file:
          F:\xampp\php\php.ini
        
        > Checking Symfony requirements:
          ................................W.WWW.....
        
        
         [OK]
         Your system is ready to run Symfony projects
        
        
        Optional recommendations to improve your setup
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
         * intl ICU version installed on your system is outdated (51.2) and
           does not match the ICU data bundled with Symfony (57.1)
           > To get the latest internationalization data upgrade the ICU
           > system package and the intl PHP extension.
        
         * a PHP accelerator should be installed
           > Install and/or enable a PHP accelerator (highly recommended).
        
         * realpath_cache_size should be at least 5M in php.ini
           > Setting "realpath_cache_size" to e.g. "5242880" or "5M" in
           > php.ini* may improve performance on Windows significantly in some
           > cases.
        
         * short_open_tag should be disabled in php.ini
           > Set short_open_tag to off in php.ini*.
        
        
        Note  The command console could use a different php.ini file
        ~~~~  than the one used with your web server. To be on the
          safe side, please check the requirements from your web
          server using the web/config.php script.
