memcache
1.下载memcache 的windows 稳定版,解压放某个盘下面,比如在H:/wamp/www/php api/memcache;
2.在终端(即cmd 命令界面)下,输入安装命令 :
H:/wamp/www/php api/memcache/memcached.exe –d install
[提示错误:failed to install service or service already installed]
解决方法:在系统盘中找到cmd.exe文件,点击右键,以管理员身份运行
3.输入命令,启动memcache服务
H:/wamp/www/php api/memcache>memcached.exe -d start
4.测试memcache是否连接成功
H:/wamp/www/php api/memcache>telnet 127.0.0.1 11211
[提示错误:'telnet' 不是内部或外部命令,也不是可运行的程序或批处理文件。]
注:windows7带有telnet,只是默认没有安装而已。
解决方法:
依次打开“开始”→“控制面板”→“打开或关闭Windows功能”,在打开的窗口处,寻找并勾选“Telnet客户端”,然后点击“确定”。顺利安装后,再在运行下输入此命令就OK了。
1.开始–>控制面板–>程序和功能
2.左侧 打开或者关闭windows功能
3.找到Telnet客户端,选择安装
5.输入:stats命令查看基本信息。
memcache连接测试运行成功!
6.输入:quit 退出
配置:
1.下载:php_memcache.dll组件。 //如果使用的是wamp5集成开发环境则自带了
2.复制:php_memcache.dll到指定的组件目录,默认在php/ext/下。
3.在php.ini中加入一句话:extension=php_memcache.dll。
4.重启WEB服务器,使用phpinfo()函数查看启用情况。
测试:
创建mem.php,源码如下:
复制代码 代码如下:
$mem = new memcache; //实例化
$mem->connect('127.0.0.1',11211) or die ("链接失败"); //127.0.0.1(服务器地址)11211(端口号)
echo $mem->getVersion(); //获得版本信息,使用echo输出
?>

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
