PHP implementation code of directory navigation file

Use PHP code to implement a directory navigation function. Add a hyperlink to the file with a specified extension in the specified directory. It is a very practical function. Friends in need can refer to it.

The following code is implemented: Add hyperlinks to the files with the specified extension in the specified directory, and you can also ignore certain specified files without navigation.

<?php
/**
 * 遍历目录 文件导航
 * by 程序员之家 bbs.it-home.org
*/
function navbar(){
$files = dir("."); //指定目录
$pipe = " | "; //管道符
//遍历目录中所有文件
while ($current = $files->read()) {
//ignor all files not of htm type.
if (strpos($current, "php")!= FALSE) //设定PHP文件被导航
//忽略自己(如 index.html)
{ if (strpos($current, "ndex") == FALSE)
{
  print "";
  print $current;
  print "";
  print $pipe;
};
};
};
};

//调用函数
navbar()
?>
