Question

我使用下面给出的链接中的相同脚本来显示目录中的文件。

Link list based on directory without file extension and hyphens in php

$directory = 'folder/';
$blacklist = array(
   'index'
);

foreach (glob($directory . "*.php") as $file) {
   $parts = pathinfo($file);
   if (!in_array($parts['filename'], $blacklist)) {
      $name = preg_replace("/-/", "", $parts['filename']);
      echo "<li><a href=\"{$file}\">{$name}</a></li>";
   }
}

上面的脚本显示文件夹中的所有文件（index.php除外）。但我只想显示五个随机文件。这可能吗？

根据您的编辑，我认为这是您尝试做的事情？

<?php
    // Get all files ending in .php in the directory
    $rand_files = glob("*.php");

    // If the string "index.php" is contained in these results, remove it
    // array_search returns the key of the $needle parameter (or false) if not found
    if (($location = array_search("index.php", $rand_files)) !== false) {
            // If "index.php" was in the results, then delete it from the array using unset()
        unset($rand_files[$location]);
    }

    // Randomly choose 5 of the remaining files:
    foreach (array_rand($rand_files, 5) as $rand_index) {
        $fname = $rand_files[$rand_index];
        echo "<a href='$fname'>$fname</a>\n";
    }
?>
