求补救匹配php字符串中的cookie
下面这是一段php字符串：
http/1.1 200 ok date: wed, 12 mar 2014 11:57:58 gmt server: apache/2.2.9 (apmserv) mod_ssl/2.2.9 openssl/0.9.8h php/5.2.6 x-powered-by: php/5.2.6 cache-control: public,max-age=10 last-modified: wed, 12 mar 2014 11:57:59 gmt set-cookie: session=cef14157b685078cf9c8f5d66fcefa81116a180d%7e53204bc7209fe349757896; expires=wed, 12-mar-2014 13:57:59 gmt; path=/; domain=.*****.com transfer-encoding: chunked content-type: text/html; charset=utf-8
我想用php正则匹配出这段字符串：
set-cookie: session=cef14157b685078cf9c8f5d66fcefa81116a180d%7e53204bc7209fe349757896;
求补救！
