如何使用PHP从文件夹中读取文件列表？

<?php
$directory = "path/to/your/folder";
$files = scandir($directory);

foreach ($files as $file) {
    if ($file != "." && $file != "..") {
        echo $file . "<br>";
    }
}
?>

<?php
$directory = "path/to/your/folder";
$files = scandir($directory);

foreach ($files as $file) {
    if ($file != "." && $file != "..") {
        $filepath = $directory . "/" . $file;
        if (is_file($filepath)) {
            echo $file . "<br>";
        }
    }
}
?>

<?php
$directory = "path/to/your/folder";
$files = glob($directory . "/*.{jpg,png,gif}", GLOB_BRACE);

foreach ($files as $file) {
    echo basename($file) . "<br>";
}
?>
