Question

我正在尝试遍历目录中的文件和子目录中的文件：

<?php

$dir = get_stylesheet_directory_uri() . '/js';

echo $dir;

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir), RecursiveIteratorIterator::SELF_FIRST );

foreach ( $iterator as $path ) {
    if ($path->isDir()) {
        print('<div> DIR : ' . $path . PHP_EOL . "</div>");
    } else {
        $path_parts = pathinfo($path);
        $file_parts = $path_parts['extension'];
        if ($file_parts == "js")
        {
            $array = explode("/opt/lampp/htdocs", $path);
            unset($array[0]);
            echo $path = implode("/", $array);
            print("<div>http://localhost$path" . PHP_EOL . "</div>");
            echo("<script src='http://localhost/$path'></script>");
        } else if ($file_parts == "css") {
            echo("<script src='http://localhost/$path'></script>");
            echo("<link rel='stylesheet' href='http://localhost/$path'>");
        }
    }
}

?>

但是，我得到了错误：

Fatal error: Uncaught UnexpectedValueException: RecursiveDirectoryIterator::__construct(http://localhost/projects/wordpress_projects/wp-content/themes/rev_cust/js): failed to open dir: not implemented in /opt/lampp/htdocs/projects/wordpress_projects/wp-content/themes/rev_cust/header.php:40

echo $dir; 给出：

http://localhost/projects/wordpress_projects/wp-content/themes/rev_cust/js

StackTrace：

如何修复它并使其正常工作？

提前谢谢大家。

Answer 1

RecursiveDirectoryIterator::__construct期望路径不是uri。要解决此问题，请尝试：

$dir = get_stylesheet_directory() . '/js'; // This gives you a path instead

Answer 2

您正在传递网址，而您必须传递路径。
