郁闷的问题，rename在foreach中不执行，
当rename($kb,$newfile.$dimg);在foreach外面的时候是执行的，
但是到了foreach里面就不行了，哪位大神讲解下？到底是咋了。怎么解决！

$hkt=$db->get_one("select fid,attachmentdomain,attachmentdir from news_sort where fid='$fid'");	$postdb[content]=str_replace("http://www_mydomain.com","../../".$attachmentdir,$postdb[content]);	$newfile="../../upload_files/".$hkt[attachmentdir]."/";	preg_match_all("/<[img|IMG].*?src=[\\\'|\\\"][^http](.*?(?:[\.gif|\.jpg]))[\\\'|\\\"].*?[\/]?>/i",$postdb[content],$imglist);	foreach($imglist[1] as $kb){		$kb=str_replace("\"","",$kb);		$dimg=explode("/",$kb);		$dimg=$dimg[count($dimg)-1];		$kbimg=$hkt[attachmentdomain]."/".$dimg;		$postdb[content]=str_replace($kb,$kbimg,$postdb[content]);		rename($kb,$newfile.$dimg);		unlink($kb);	}

回复讨论(解决方案)

循环中打印出来$kb,$newfile,$dimg等分别是什么。
要学会一步一步跟踪调试

均以测试了的！就是在foreach中不行。。下面的unlink都执行了，就是rename不执行！

循环中打印出来$kb,$newfile,$dimg等分别是什么。
要学会一步一步跟踪调试
$kb=老的图片路径，“../../img/A.jpg”
$newfile=新储存路径,"../../newimg/"
$dimg=是图片的名称:"a.jpg"

搞定了！呼呼！ $newfile不是绝对路径所致！
