列出指定目录下所有文件的PHP代码?

Jun 23, 2016 pm 02:10 PM

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;}
Copy after login


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 />';}
Copy after login
Copy after login
Copy after login
Copy after login

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;
Copy after login
Copy after login
Copy after login

Copy after login

csdn总算能看到引用的代码了……呵呵

我是来学习的

太犀利了!

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

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

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?

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

What is REST API design principles? What is REST API design principles? Apr 04, 2025 am 12:01 AM

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

How do you handle exceptions effectively in PHP (try, catch, finally, throw)? How do you handle exceptions effectively in PHP (try, catch, finally, throw)? Apr 05, 2025 am 12:03 AM

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

What are anonymous classes in PHP and when might you use them? What are anonymous classes in PHP and when might you use them? Apr 04, 2025 am 12:02 AM

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.

What is the difference between include, require, include_once, require_once? What is the difference between include, require, include_once, require_once? Apr 05, 2025 am 12:07 AM

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.

Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Apr 08, 2025 am 12:03 AM

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.
