/**
 * 单文件版在线代码编辑器 editor.php 版本: v1.21
 * 
 * 密码加密方式: 
 * md5(自设密码+$ace) //$ace为cdn镜像地址
 * 
 * 使用方法: 
 * 1.确认 $pwd 变量值为 false, 上传本文件到PHP空间并访问
 * 2.第一次访问提示设置密码,设置密码并牢记
 * 3.使用第一次设置的密码登录后,默认编辑的是本php文件,
 * 4.本文件是编辑器核心文件,请不要随意修改
 * 5.保存编辑的文件请用 Ctrl + S 按键组合,等待执行结果
 * 6.保存动作执行后请务必等待保存成功信息返回
 * 7.重置操作会修改本程序的文件名，以防他人猜测路径
 * 8.刷新功能仅是刷新本程序文件，不能刷新其他
 * 
 * 建议在 chrome 浏览器中使用本编辑器
