The simplest and most fun way (imo) is glob
最简单最有趣的方式（imo）就是glob
foreach (glob("*.*") as $filename) {
echo $filename."<br />";
}
But the standard way is to use the directory functions.
但标准的方法是使用目录函数。
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "filename: .".$file."<br />";
}
closedir($dh);
}
}
There are also the SPL DirectoryIterator methods. If you are interested
还有SPL DirectoryIterator 方法。如果你感兴趣

This is what I like to do:
这是我喜欢做的事情：
$files = array_values(array_filter(scandir($path), function($file) use ($path) {
return !is_dir($path . '/' . $file);
}));
foreach($files as $file){
echo $file;
}

There is this function scandir():
有这个函数scandir()：
$dir = 'dir';
$files = scandir($dir, 0);
for($i = 2; $i < count($files); $i++)
print $files[$i]."<br>";

If you have problems with accessing to the path, maybe you need to put this:
如果您在访问路径时遇到问题，也许您需要这样写：
$root = $_SERVER['DOCUMENT_ROOT'];
$path = "/cv/";
// Open the folder
$dir_handle = @opendir($root . $path) or die("Unable to open $path");

Check in many folders :
检查许多文件夹：
Folder_1 and folder_2 are name of folders, from which we have to select files.
Folder_1 和 folder_2 是文件夹的名称，我们必须从中选择文件。
$format is required format.
$format 是必需的格式。
<?php
$arr = array("folder_1","folder_2");
$format = ".csv";
for($x=0;$x<count($arr);$x++){
$mm = $arr[$x];
foreach (glob("$mm/*$format") as $filename) {
echo "$filename size " . filesize($filename) . "<br>";
}
}
?>

You can use standard directory functions
您可以使用标准目录功能
$dir = opendir('/tmp');
while ($file = readdir($dir)) {
if ($file == '.' || $file == '..') {
continue;
}
echo $file;
}
closedir($dir);
