php visitFile()遍历指定文件夹函数

注:visitFile()有少量修改

<? 
// 查看指定文件夹的文件 
$fileList = array(); 
function visitFile($path) 
{ 
global $fileList; 
$path = str_replace("\\", "/", $path); 
$fdir = dir($path); 
while (($file = $fdir->read()) !== false) 
{ 
if($file == '.' || $file == '..'){ continue; } 
$pathSub = preg_replace("*/{2,}*", "/", $path."/".$file); // 替换多个反斜杠 
$fileList[] = is_dir($pathSub) ? $pathSub."/" : $pathSub; 
if(is_dir($pathSub)){ visitFile($pathSub); } 
} 
$fdir->close(); 
return $fileList; 
}
