专为给喜欢逛论坛的你设计...
<?php $path = "./img/". preg_replace('/[^a-zA-Z0-9]/i','',$_GET['id'] ); if (is_dir($path)){ $url = $path ; } else { $url = "./img/nobird"; } $files = array(); if(false !== ($handle = @opendir($url))) { while($file = readdir($handle)) { if(($file !== ".")&&($file !== "..")) { if((substr($file,-3) == "gif") || (substr($file,-3) == "jpg") || (substr($file,-3) == "png")) $files[count($files)] = $file; } } closedir($handle); $random = rand(0,(count($files)-1)); //设定随机数的范围; //根据文件类型,设置输出的文件类型; if(substr($files[$random],-3) == "gif") header("Content-type:image/gif"); elseif(substr($files[$random],-3) == "jpg") header("Content-type:image/jpeg"); elseif(substr($files[$random],-3) == "png") header("Content-type:image/png"); readfile("$url/$files[$random]"); //读文件,显示图片; }else { $im = imagecreatetruecolor(500, 100); $bgc = imagecolorallocate($im, 255, 255, 255); $tc = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, 500, 100, $bgc); imagettftext($im,15,0,5,20,$tc,$font,iconv("gb2312","UTF-8","图片载入出错,请向我报告!")); imagettftext($im,15,0,6,36,$tc,$font,iconv("gb2312","UTF-8",$imgname)); } ?>
和网上流传甚多的版本比较起来,这个支持id,也就是说,一个文件,可以为多个账户服务(我就是一篇凑数的文章,你特么来咬我呀).
