[PHP] - visitFile()遍历指定文件夹

visitFile()函数来源：http://topic.csdn.net/u/20071225/11/e6a8db84-df02-4622-987b-2a4ed4a5eef0.html (第14楼)

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;
}
?>
