PHP程序指定目录里的指定后缀名文件为超连接

<?php

function navbar()
{
files = dir("."); //指定目录
pipe = " | "; //管道符
//通过以下的循环搜索目录中所有文件
while (current = files->read())
{
//ignor all files not of htm type.
if (strpos(current, "php\")!= FALSE) //设定后缀为PHP的文件将被导航
//忽略自己(如 index.html)
{

if (strpos(current, "ndex") == FALSE)
{
print "<a href='";
print current;
print "'>";
print current;
print "</a>";
print pipe;
};
};
};
};
navbar() //调用函数
?>
