PHP7新建扩展
1、你已经配置过PHP7的开发环境。
1.1 检查centos安装源
yum list installed | grep php
有则删除旧的:
yum remove php*
1.2 添加新的安装源
# CentOS 5.Xrpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm# CentOs 6.xrpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm# CentOs 7.Xrpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpmrpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
想要删除上面的安装包:
rpm -qa | grep webstatic
1.3 安装PHP开发环境
yum install php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-devel.x86_64
2、下载一份对应版本的PHP源代码
cd php_src/ext/./ext_skel --extname=hello
进入源代码的ext目录,并新建一个hello的插件;extname参数的值就是扩展名称。执行ext_skel命令后,这样在当前目录下会生成一个与扩展名一样的目录。
3、修改config.m4配置文件
cd hellovim config.m4
打开,config.m4文件后,你会发现以下内容
dnl If your extension references something external, use with: dnl PHP_ARG_WITH(say, for say support, dnl Make sure that the comment is aligned: dnl [ --with-say Include say support]) dnl Otherwise use enable: dnl PHP_ARG_ENABLE(say, whether to enable say support, dnl Make sure that the comment is aligned: dnl [ --enable-say Enable say support])
其中,dnl 是注释符号。
上面的代码说,如果你所编写的扩展如果依赖其它的扩展或者lib库,需要去掉PHP_ARG_WITH相关代码的注释。
否则,去掉 PHP_ARG_ENABLE 相关代码段的注释。我们编写的扩展不需要依赖其他的扩展和lib库。因此,我们去掉PHP_ARG_ENABLE前面的注释。
去掉注释后的代码如下:
dnl If your extension references something external, use with: dnl PHP_ARG_WITH(say, for say support, dnl Make sure that the comment is aligned: dnl [ --with-say Include say support]) dnl Otherwise use enable: PHP_ARG_ENABLE(say, whether to enable say support, Make sure that the comment is aligned: [ --enable-say Enable say support])
4、修改代码
修改 hello.c 文件,实现 hello() 函数;找到 PHP_FUNCTION(confirm_hello_compiled) 在上面添加以下内容:
PHP_FUNCTION(hello){ zend_string *strg; strg = strpprintf(0, "hello word,dingdayu"); RETURN_STR(strg);}
PHP_FUNCTION 为定义PHP内部函数括号里面的为函数名,然后再使用下面的修改将函数公开到插件外部。
找到 PHP_FE(confirm_hello_compiled 在上面增加如下代码:
PHP_FE(hello, NULL)
即修改后效果:
const zend_function_entry hello_functions[] = { PHP_FE(hello, NULL) /* For testing, remove later. */ PHP_FE(confirm_hello_compiled, NULL) /* For testing, remove later. */ PHP_FE_END /* Must be the last line in say_functions[] */ }; /* }}} */
其中上面的代码中“confirm_hello_compiled”为测试函数,可在实际项目中删除
5、编译
phpize./configuremakemake test# 会提醒输入邮箱make install# 会提示编译后输入的目录 目测:/lib64/php/modules/hello.so
6、添加配置
[hello]extension = hello.so
7、测试效果
你可以使用 “php -m”查看加载扩展,不过这里请注意,如果php-cli命令和web php的配置文件不是同一个配置文件,则可能会出现差错,推荐先通过phpinfo();查看web php配置文件,然后使用“php --ini”查看php-cli配置文件。
楼主web的php-fpm是编译的,php-cli是通过yum安装的,所以不同。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
