PHP 7.1.21 和 7.2.9 正式发布，多项内容修复

PHP（外文名:PHP: Hypertext Preprocessor，中文名：“超文本预处理器”）是一种通用开源脚本语言。语法吸收了C语言、Java和Perl的特点，利于学习，使用广泛，主要适用于Web开发领域。PHP 独特的语法混合了C、Java、Perl以及PHP自创的语法。它可以比CGI或者Perl更快速地执行动态网页。用PHP做出的动态页面与其他的编程语言相比，PHP是将程序嵌入到HTML（标准通用标记语言下的一个应用）文档中去执行，执行效率比完全生成HTML标记的CGI要高许多；PHP还可以执行编译后代码，编译可以达到加密和优化代码运行，使代码运行更快。
