memcache
(其实在Windows下安装还是比较简单的)
源码包准备:
1,memcached 1.2.1 for Win32 binaries
这个是 Win32 服务器端的 memcached 最新版本,直接下载就可以了;
2,php_memcache-5.2-Win32-vc6-x86-20090408.zip
这个是 php 所需的 PECL 扩展,即 php_memcache 扩展;(一定要和自己的 PHP 版本相同,我用的是5.2.1)
有了源码包包,那就开始大快朵颐吧,按照下面的步骤
1. 将第一个包解压放某个盘下面,比如在c:\memcached
2. 在终端(也即cmd命令界面)下输入 ‘c:\memcached\memcached.exe -d install' 安装
3. 再输入: ‘c:\memcached\memcached.exe -d start' 启动。(需要注意的: 以后memcached将作为windows的一个服务每次开机时自动启动。这样服务器端已经安装完毕了)
4. 解压第二个包包,里面会只有一个 php_memcache.dll 文件,把它放入 usr/local/php5/ext/ 中
5. 在C:\WINDOWS\php.ini 加入一行 ‘extension=php_memcache.dll'(不知道为什么 PHP 会有两个配置文件,一个在 usr/local/php5/php.ini, 而另一个则在 C:/WINDOWS/中,而且只改前一个配置文件不起作用,所以就把 WINDOWS 中的 php.ini 也改掉了!)
6,接着在 php.ini 文件里加上:
复制代码 代码如下:
[Memcache]
memcache.allow_failover = 1
memcache.max_failover_attempts=20
memcache.chunk_size =8192
memcache.default_port = 11211
最好就放在刚才写 "extension=php_memcache.dll" 的下面。(这是默认的一些配置)
6.重新启动Apache,然后查看一下phpinfo,如果有 memcache 的说明,那么就说明安装成功啦!
试运行:
写一个 example.php 文件:(更多使用方法可以参看 PHP 手册里的 Memcache Functions 使用说明)
复制代码 代码如下:
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");
$version = $memcache->getVersion();
echo "Server's version: ".$version."
\n";
$tmp_object = new stdClass;
$tmp_object->str_attr = 'test';
$tmp_object->int_attr = 123;
$memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");
echo "Store data in the cache (data will expire in 10 seconds)
\n";
$get_result = $memcache->get('key');
echo "Data from the cache:
\n";
var_dump($get_result);
?>
如果有输出:
复制代码 代码如下:
Server's version: 1.4.5
Store data in the cache (data will expire in 10 seconds)
Data from the cache:
object(stdClass)#3 (2) { ["str_attr"]=> string(4) "test" ["int_attr"]=> int(123) }
则说明,我们的 Memcached 已经正常运行啦! :~>

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
