跳转php

php,我模拟手机浏览器去访问yahoo的页面,取得商品的url如下:
http://ord.yahoo.co.jp/o/shopping/_ylt=A7dPdCbPKx5V.SgAqVET.Pl7/SIG=14t4hc3s6/EXP=1428127055/**http%3a//rdsig.yahoo.co.jp/search/direct/promodd/evt=90004/RV=1/RU=aHR0cDovL3N0b3JlLnNob3BwaW5nLnlhaG9vLmNvLmpwL21hdHN1bmFtaS9mY2RtMy5odG1s" onmousedown="if (checkSiteCatalyst()) {YAHOO.JP.sc.clickSearchResultPos('item=search|type=organic|disp=20|pg=1|pos=1')}
点击该商品名(如上url)后,就会跳转到该商品的页面,url如下:
http://store.shopping.yahoo.co.jp/matsunami/fcdm3.html
能不能根据从页面上取得的url,获得跳转后的url?
