PHP reads all file names in the specified directory folder_PHP tutorial

We will use several functions to traverse the file names in the directory and display them. One is the opendir directory reading function, and then use readdir to obtain the directory information into an array and then traverse it through while.

Show all files in the directory

The code is as follows

代码如下	复制代码
$dir=dirname(__FILE__)."/../www.bKjia.c0m /";//这里输入其它路径 //PHP遍历文件夹下所有文件 $handle=opendir($dir."."); //定义用于存储文件名的数组 $array_file = array(); while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { $array_file[] = $file; //输出文件名 } } closedir($handle); print_r($array_file); ?>

Copy code

 代码如下

复制代码

/**
 * 删除指定目录下的所有文件
 *
 * @param String $dir  要进行操作的路径
 * 适合范围，只有用于文件夹内不存在子文件夹的情况下

function dir_clear($dir) {
    $directory = dir($dir);                //创建一个dir类(bKjia.c0m的PHP手册上这么说的)，用来读取目录中的每一个文件
    while($entry = $directory->read()) {   //循环每一个文件,并取得文件名$entry
        $filename = $dir.'/'.$entry;       //取得完整的文件名，带路径的
        if(is_file($filename)) {           //如果是文件，则执行删除操作
            @unlink($filename);
        }
    }
    $directory->close();                   //关闭读取目录文件的类
    result();
}  

$dir=dirname(__FILE__)."/../www.bKjia.c0m /";//Enter other paths here //PHP traverses all files in the folder $handle=opendir($dir."."); //Define an array for storing file names

$array_file = array();

while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { $array_file[] = $file; //Output file name } } closedir($handle); print_r($array_file); ?>

Delete all files in the specified directory
