代码高亮KindSyntax Version 1.0

作者：Roddy， 来源：网络， 阅读：182， 发布时间：2014-05-10

KindSyntax是用PHP做的程序语法加亮类，支持HTML、 JavaScript、 PHP、 Perl等语言的高亮显示，可以替代PHP自带的highlight函数。使用方法： <strong>1) 直接读源代码文件时 </strong>1. 根据扩展名适用不同的加亮规则 $stx = new STX(); echo $stx->stx_file($file); 2. 指定一个规则 $stx = new STX('perl'); echo $stx->stx_file($file); <strong>2) 加亮字符串时： </strong>$stx = new STX('php'); echo $stx->stx_string($file); 注意：EditPlus的stx文件要放在相同目录里，stx文件下载：<a href="http://www.editplus.com/files.html">http://www.editplus.com/files.html</a> ，如果你已经安装了EditPlus，直接去安装目录能找到这些文件。 win和bsd主机下可能会出错，Error 内容是: Warning: in_array(): Wrong datatype for second argument in h:\akil_board\estclass.stx.php on line 203 Warning: in_array(): Wrong datatype for second argument in h:\akil_board\estclass.stx.php on line 237 Warning: in_array(): Wrong datatype for second argument in h:\akil_board\estclass.stx.php on line 239 打开class.stx.php 查找：$root_path = preg_replace("/^(.*/)(.*)$/","",__FILE__); 替换为：$root_path = (substr(PHP_OS,0,3) =='WIN') ? dirname(__FILE__).'\\' : dirname(__FILE__).'/'; 修改后测试 WIN 和 BSD 正常。
