我想很多站长都知道fck这个编辑器吧，fck是一个在线文档编辑器，上传的图片是不会保存到数据库中的，所以我们要想办法把它正则出来，下面是一个正则fck input图像域的代码。
function get_img($str){
$dpath = 'images/img.jpg';
preg_match('/]*>/im',stripslashes(stripslashes($str)), $arr);
preg_match('/src=(.+?)"/im', $arr[0], $arra);
if( strlen(@$arra[1])>10 ){
$dpath = str_replace(""","",@$arra[1]);
}
return "";
}
