php编译openssl模块的步骤
最近我们打算在php框架中使用composer来管理依赖关系,但是在执行composer的安装命令时(如下),发现系统提示没有安装openssl扩展类库。
安装composer命令:
sudocurl -s https://getcomposer.org/installer | sudo php
异常如下:
Some settings onyour machine make Composer unable to work properly. Make sure thatyou fix the issues listed below and run this script again: The opensslextension is missing, which means that secure HTTPS transfers areimpossible. If possible youshould enable it or recompile php with --with-openssl |
看到这个异常,应该是我的php在编译的过程中没有增加-with-openssl选项造成的。但是在网上搜索相关问题时,发现我们不需要重新编译php环境,可以借助phpize来只编译openssl.so文件,并把该文件添加到php.ini文件中的。
1.环境
1)操作系统:
Linuxubuntu 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014x86_64 x86_64 x86_64 GNU/Linux
2)php源码目录:
/home/wuguowei/software/php-5.5.14_source
3)php编译后的目录:
/home/wuguowei/software/php5.5
2.步骤
#从源码目录拷贝openssl目录到编译后的目录文件中
sudocp -r /home/wuguowei/software/php-5.5.14_source/ext/openssl /home/wuguowei/software/php5.5/include/php/ext
#进入php编译后的目标文件中
cd/home/wuguowei/software/php5.5/include/php/ext
#依次执行如下代码
/home/wuguowei/software/php5.5/bin/phpize
./configure--with-openssl?with-php-config=/home/wuguowei/software/php5.5/bin/php-config
make&& make install
#找到php.ini文件(通常在/etc/php.in)中的“DynamicExtensions”的内容,在末尾添加上“extension= openssl.so”
#重启php服务器即可
#查看编译后的openssl的方法
php-i |grep 'openssl'
正确的结果如下:
root@ubuntu:/home/wuguowei/software/composer#php -i |grep openssl openssl OLDPWD=> /home/wuguowei/software/php5.5/include/php/ext/openssl _SERVER["OLDPWD"]=> /home/wuguowei/software/php5.5/include/php/ext/openssl |
#查看php命令在哪儿的命令

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

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),
