PhalconPHP and PHP7

2016-03-16

From: http://phalcon.io/phalconphp-and-php7

PHP7 was released on the 3rd of December, 2015. This new version brought forward a large number of new and exiting features (http://php.net/manual/en/migration70.new-features.php) to PHP. Perhaps one of the biggest of the new features is a new Zend Engine (the engine that powers PHP).

This new engine, code named PHPNG, will give some of your applications double the performance speed.

Some benchmarks that have been run so far:

WordPress 3.6 – 20.0% gain (253 vs 211 req/sec)
Drupal 6.1 – 11.7% gain (1770 vs 1585 req/sec)
Qdig – 15.3% gain (555 vs 482 req/sec)
ZF test app – 30.5% gain (217 vs 166 req/sec)
It is only natural that once it came out the PhalconPHP community was dying to know when we would get a chance to work with PhalconPHP and PHP7.

The Problem

We all know that PhalconPHP is written in Zephir starting with version 2.0, and that this language compiles its code into a C PHP Extension. Because of PHP7’s new engine the extension had to be rewritten and adapted to the new specifications.

The Solution

Knowing this, the PhalconPHP team started working since last year on an updated version of Zephir to make the compiled code work with PHP7.

After a few months we are finally delivered PhalconPHP 2.1 and Zephir 0.9.x which brings PHP7 support.

Installing PhalconPHP with PHP7

You will need to install PHP7+ and Zephir 0.9.2a-dev (or its latest branch). After you have them installed go to PhalconPHP 2.1.0+ branch and download the source code.

Installation example:

root@localhost:~$ cd cphalcon-2.1.x/
root@localhost:~/cphalcon-2.1.x$ zephir build —backend=ZendEngine3

1 2	root@localhost:~$ cd cphalcon-2.1.x/ root@localhost:~/cphalcon-2.1.x$ zephir build —backend=ZendEngine3

If you get these warnings ignore them:

     }

That’s it!

You now have PhalconPHP and PHP7 working.

Can you expect PhalconPHP to be even faster? No, but you can expect to see your your app be much faster since your PHP code will run better with the new engine. Plus, you won’t have any overhead since PhalconPHP is a extension. The best part of all this is that you get all the new features that PHP7 brings to the table.

Do take into account that PHP7 is still rather new, and most of the commonly used extensions like memcache, memcached, and redis are available in Dev/Beta branches, so you need to reinstall them.

Best of luck to all and enjoy PhalconPHP + PHP7.

Phalcon 连接数据库中文字符集的问题

2014-08-11

网上的方法都是在配置里面添加charset，结果我苦逼的调试了好一会。

后来才发现我的php版本是5.3.3的，这样是不行滴！

5.3.6 Prior to version 5.3.6, charset was ignored.

        $di['db'] = function () use ($config) {
            $conn = new DbAdapter(array(
                "host" => $config->database->host,
                "username" => $config->database->username,
                "password" => $config->database->password,
                "dbname" => $config->database->dbname,
                "charset" => 'utf8', // 在php 5.3.6之前无效
            ));

            $conn->query("set names utf8");// 变通解决办法
            return $conn;
        };

$di['db'] = function () use ($config) {

$conn = new DbAdapter(array(

"host" => $config->database->host,

"username" => $config->database->username,

"password" => $config->database->password,

"dbname" => $config->database->dbname,

"charset" => 'utf8', // 在php 5.3.6之前无效

));

$conn->query("set names utf8");// 变通解决办法

return $conn;

};

悲催的电信？几经劫持，估计都没有人知道~

2014-05-09

访问公司的内网网址，结果因为没连VPN，发现DNS找不到域名，以前会跳到电信的一个提示页面（也都是广告啦）。今天倒好，跳到一个不知名的垃圾站，可悲的是还出现错误。

看名字就是一个广告联盟，可恶你劫持电信，自己也好好搞哈，用户体验这么差，我勒个去！

ll0o.com 一个山寨、垃圾、无耻的地址！没人会相信这个跟中国电信有关系吧？电信自己被黑了估计不知道！
