php 读取目录下图像文件
本款是一款php 读取目录下图像文件代码,利用了opendir来打开目录然后获取文件后缀名,判断是否为指定文件.
php 读取目录下图像文件实例代码如下:
<?php $directory = 'gallery'; $allowed_types = array( 'jpg', 'jpeg', 'gif', 'png' ); $file_parts = array(); $ext = ''; $title = ''; $i = 0; $dir_handle = @opendir($directory) or die("there is an error with your image directory!"); while ($file = readdir($dir_handle)) { if ($file == '.' || $file == '..') continue; $file_parts = explode('.', $file); $ext = strtolower(array_pop($file_parts)); $title = implode('.', $file_parts); $title = htmlspecialchars($title); $nomargin = ''; if (in_array($ext, $allowed_types)) { if (($i + 1) % 4 == 0) $nomargin = 'nomargin'; echo ' <div class="pic ' . $nomargin . '" style="background:url(http://pic1.phprm.com/2014/08/19/' . jpg) no - repeat50 % 50 %; "> <a href="http: //pic1.phprm.com/2014/08/19/'.jpg" title="'.$title.'" target="_blank">'.$title.'</a> < / div >; $i++; } } closedir($dir_handle);
