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?

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
