最简单和最有趣的方式(imo)是 glob

foreach (glob("*.*") as $filename) {
    echo $filename."<br />";
}

但标准的方法是使用 directory functions.

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: .".$file."<br />";
        }
        closedir($dh);
    }
}

还有 SPL DirectoryIterator methods . 如果你感兴趣

有这个功能 斯堪的纳维亚

$dir = 'dir';
$files = scandir($dir, 0);
for($i = 2; $i < count($files); $i++)
    print $files[$i]."<br>";

More here in the php.net manual

这就是我喜欢做的:

$files = array_values(array_filter(scandir($path), function($file) use ($path) { 
    return !is_dir($path . '/' . $file);
}));

foreach($files as $file){
    echo $file;
}

如果您在访问路径时遇到问题,可能需要:

$root = $_SERVER['DOCUMENT_ROOT'];
$path = "/cv/"; 

// Open the folder
 $dir_handle = @opendir($root . $path) or die("Unable to open $path");

签入多个文件夹:

<?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>";
    }
}
?>

您可以使用标准目录函数

$dir = opendir('/tmp');
while ($file = readdir($dir)) {
    if ($file == '.' || $file == '..') {
        continue;
    }

    echo $file;
}
closedir($dir);
