PHP和Tomcat整合
我的软件如下:
Apache2.2 ?目录:C:\Program Files (x86)\Apache Software Foundation\Apache2.2
Tomcat 5.5 目录:D:\apache-tomcat-5.5.25
PHP 目录:D:\DEV\php-5.2.13-Win32-VC6-x86
MySql Server5.2 目录:C:\Program Files (x86)\MySQL\MySQL Server 5.2
JK插件:mod_jk-1.2.28-httpd-2.2.3.so
?
需要做如下设置:
1. 安装Apache2.2,过程中让你选择域名和端口,我写的是www.seya.com,端口:80. 邮箱写个自己的好了:seyason@gmail.com.这些都在配置文件httpd.conf里,后面也可以自己改的。
?
2. 安装java JDK和设置Tomcat 环境变量,CATALINA_HOME和CATALINA_BASE设置到tomcat的根目录就行了,保证在tomcat下的bin目录下运行catalina start命令能跑起来。
?
3. 安装MySql Server5.2 都按默认配置好了,一路Next. 设置root账号的密码,比如是111111.
?
4. 配置PHP服务,让它能同时提供PHP和JSP的服务。
1》将php安装目录下的php.ini-dist文件改名为php.ini, 去掉这几行前面的分号(取消注释)
? extension=php_mbstring.dll
? extension=php_dbase.dll
? extension=php_gd2.dll
? extension=php_mysql.dll
并改extension_dir =”extension_dir = "D:/DEV/php-5.2.13-Win32-VC6-x86/ext/“ 以上那几个文件就在这个目录下。
2》配置Apache,修改C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf文件
修改 DocumentRoot "D:/DEV/php-5.2.13-Win32-VC6-x86/webroot/"
修改
在ScriptAlias /cgi-bin/ "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/cgi-bin/"下面增加几行,使其支持PHP服务:
??? ScriptAlias???????????? /php/? "D:/DEV/php-5.2.13-Win32-VC6-x86/"
??? addtype??????????? application/x-httpd-php .php
??? action????????? application/x-httpd-php "/php/php.exe"
3》加载PHP模块和JK模块
?? LoadModule php5_module "D:/DEV/php-5.2.13-Win32-VC6-x86/php5apache2_2.dll"
?? AddHandler application/x-httpd-php .php
?? # configure the path to php.ini
?? PHPIniDir "D:/DEV/php-5.2.13-Win32-VC6-x86"
?? LoadModule jk_module modules/mod_jk-1.2.28-httpd-2.2.3.so
4》配置和Tomcat的集成
? 在D:\DEV\php-5.2.13-Win32-VC6-x86下新建目录ConnApaTom,在其下新建文件workers.properties, 内容如下:
? workers.tomcat_home=D:\apache-tomcat-5.5.25
workers.java_home=C:\Program Files (x86)\Java\jdk1.5.0_05
worker.list=ajp12, ajp13
worker.ajp12.port=8007
worker.ajp12.host=localhost
worker.ajp12.type=ajp12
worker.ajp12.lbfactor=1
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=ajp12, ajp13
worker.inprocess.type=jni
worker.inprocess.class_path=$(workers.tomcat_home)$(ps)lib$(ps)tomcat.jar
worker.inprocess.cmd_line=start
worker.inprocess.jvm_lib=$(workers.java_home)$(ps)jre$(ps)bin$(ps)classic$(ps)jvm.dll
worker.inprocess.stdout=$(workers.tomcat_home)$(ps)logs$(ps)inprocess.stdout
worker.inprocess.stderr=$(workers.tomcat_home)$(ps)logs$(ps)inprocess.stderr
?
然后再修改C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf文件, 加这么几行:
JkWorkersFile "D:/DEV/php-5.2.13-Win32-VC6-x86/ConnApaTom/workers.properties"
JkMount /servlet/* ajp13
JkMount /*.jsp ajp13
JkMount /*.do? ajp13
就是把.jsp, .do 和 /servlet的请求转到workers.properties中设置的路径去处理,也就是D:\apache-tomcat-5.5.25。 实现了将JSP整合到了PHP server下。
?
至此配置工作完成,重启Apache和Tomcat。把你的JSP项目,或者php项目放在D:\DEV\php-5.2.13-Win32-VC6-x86\webroot目录下,通过localhost:80端口都可以访问了。

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
