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?

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,

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.

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.

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.

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.

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.

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.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.
