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。
/etc/php.ini/usr/local/php7/etc/php.ini
