获取目录中图像的文件名 [英] Get filenames of images in a directory

问题描述

应该怎么做才能使用PHP从文件夹/目录中获取图像标题(例如abc.jpg)并将其存储在数组中.

What should be done to get titles (eg abc.jpg) of images from a folder/directory using PHP and storing them in an array.

例如:

a[0] = 'ac.jpg'
a[1] = 'zxy.gif'

等

我将在幻灯片放映中使用该阵列.

I will be using the array in a slide show.

推荐答案

当然有可能.查看 opendir的文档，然后将每个文件推送到结果数组.如果您使用的是PHP5，请查看 DirectoryIterator .这是遍历目录内容的一种更流畅，更干净的方法！

It's certainly possible. Have a look at the documentation for opendir and push every file to a result array. If you're using PHP5, have a look at DirectoryIterator. It is a much smoother and cleaner way to traverse the contents of a directory!

编辑:建立在 opendir 上:

$dir = "/etc/php5/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        $images = array();

        while (($file = readdir($dh)) !== false) {
            if (!is_dir($dir.$file)) {
                $images[] = $file;
            }
        }

        closedir($dh);

        print_r($images);
    }
}
