$del=array("/name=.+?['|\"]/i","/src=.+?['|\"]/i","/id=.+?['|\"]/i","/width=.+?['|\"]/i","/height=.+?['|\"]/i","/usemap=.+?['|\"]/i","/shape=.+?['|\"]/i","/coords=.+?['|\"]/i","/target=.+?['|\"]/i","/title=.+?['|\"]/i");
$file = preg_replace($del,"",$file);//去除style样式
$file = str_replace(" ","",$file);//去除所有空格
$file = str_replace("<ahref=","<a href=",$file);//还原空格
echo $file;
