实测windows系统使用cmd搜索包含某个关键词的代码及PHP自动生成数据字典
1.windows系统下进入cmd窗口-->替换自己的路径，执行下面命令
findstr /s /i "carlist" D:\phpstudy_pro\WWW\wxx\*.*
2.php自动生成数据字典
<?php
// $t1 = microtime(true);
// 执行代码
// $t2 = microtime(true);
// echo '耗时:'.round($t2-$t1,3).'秒<br>';
// echo '内存: ' . round((memory_get_usage()/1024/1024),3) . 'M<br />';
