PHP的Zlib和gzhandle
请高手无视内容.....
纯笔记
PHP的压缩传输可以使用php.ini中设置Zlib.output_compression=on,此时所有的PHP输出都会经过压缩 或者修改程序对指定要压缩的程序进行ob_start("ob_gzhandler");来实现压缩。
AMFPHP使用gzhandler压缩。
压缩的原理都一样,都是使用Zlib extension来操作,所以一定要load zlib.so,两种方式在同一个页面只能任选其一,否则会冲突。
使用ob_gzhandler的话实际调用ext/zlib/zlib.c的ob_gzhandler,来检测浏览器支持的压缩类型,执行gzip就用gzip压缩或者deflate.
?
ob_start();
ob_start('ob_gzhandler');
ob_end_flush();
header("Content-length: " . ob_get_length());
ob_end_flush();

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),
