你分析一下原数组，你看键值0 就不需要改了吧。这样你就直接赋值给新数组$new
然后循环原数组
foreach($old as $key=$val){
//具体的你自己去写正则把,我只是写个大概,把匹配到的剩余 $match[1] 赋值给 $new
if( preg_match(("/^(Content-Type:)/",$val,$match) ){
$new['Content-Type'] = $match[1];
}elseif(preg_match('/^(Server:)/',$val)){
$new['Server'] = $match[1];
}elseif(.....){
依次类推
