列出指定目录下所有文件的PHP代码?
比如说我用代码只能列出当前目录的文件及目录。
bak
1.php
1.txt
123
........
但是我发现了 我是要bak文件夹下的文件。(bak目录的绝对路径和相对路径都是已知的。)
请赐代码 本人不太懂得写代码.
回复讨论(解决方案)
你写的不对,当然就不行
function get_files($dir){ $files = array(); if(is_dir($dir)){ if($dh = opendir($dir)){ while (($file = readdir($dh)) !== false) { if(!($file == '.' || $file == '..')){ $file = $dir.'/'.$file; if(is_dir($file) && $file != './.' && $file != './..'){ $files = array_merge($files, get_files($file)); } else if(is_file($file)){ $fullpath = $_SERVER['HTTP_REFERER']; $fullpath = str_replace(basename($fullpath),"",$fullpath); $fullpath .= substr($file,2); $files[] = $fullpath; } } } } } return $files;}
使用方法
$path = '../bak';
foreach(get_files($path) as $allfile){
echo $allfile.'
';
}
使用迭代器,既简单又迅速
$path = '目录名';$ite = new RecursiveDirectoryIterator($path);foreach (new RecursiveIteratorIterator($ite) as $filename=>$cur) { $fn = $cur->getBasename(); if($cur->isDir() || ($fn == '.' || $fn == '..')) continue; echo $filename, '<br />';}
既然用迭代器,就不用判断isdir那么麻烦,默认就是leaves only的
$items = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));foreach($items as $itemName => $item) echo (string)$itemName, '<br />', PHP_EOL;

csdn总算能看到引用的代码了……呵呵
我是来学习的

是吗?
像 app/Admin/.. 这样的不是也输出了吗?
倒是只判断 isDir() 就可以只输出文件名了

没有一个可以 继续等完整代码中。。。。。。
php文档内说的递归器就是默认去枝留叶方式,要输出节点应转换参数,如果有输出dir名那就不清楚是否未完善的bug

说一些有用的东西吧~!继续等完整代码中。。。。。。
真奇了怪了!
你说说上面那段代码没有用?
超出想象,难道不懂怎么赋值给$path还是不懂从返回中提取?
