😁做个图集吧嫌麻烦,于是…

~具体效果参考右边侧栏最下面~

不行,我还是放文章内置顶吧…不能放外面.

方法一:

<?php
/**********************************************
 * Filename : img.php
 * Author : freemouse
 * Usage:
 * <img src=img.php>
 * <img src=img.php?folder=images2/>
 ***********************************************/
if ($_GET['folder']) {
    $folder = $_GET['folder'];
} else {
    $folder = '/images/';
}
//存放图片文件的位置
$path = $_SERVER['DOCUMENT_ROOT'] . "/" . $folder;
$files = array();
if ($handle = opendir("$path")) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            if (substr($file, -3) == 'gif' || substr($file, -3) == 'jpg') {
                $files[count($files)] = $file;
            }

        }
    }
}
closedir($handle);
$random = rand(0, count($files) - 1);
if (substr($files[$random], -3) == 'gif') {
    header("Content-type: image/gif");
} elseif (substr($files[$random], -3) == 'jpg') {
    header("Content-type: image/jpeg");
}

readfile("$path/$files[$random]");
?>

方法二:

<?php
$img_array = glob('images/*.{gif,jpg,png,jpeg,webp,bmp}', GLOB_BRACE);
if (count($img_array) == 0) {
    die('没找到图片文件。请先上传一些图片到 ' . dirname(__FILE__) . '/images/ 文件夹');
}

header('Content-Type: image/png');
echo (file_get_contents($img_array[array_rand($img_array)]));
?>
