我想在前端显示成固定播放页面播放，样式如：https://www.a.com/js/player/ck.html?videourl=受后台加密设置影响的视频地址   的格式，就是说不要iframe的相关代码，不要pn判断，用一个超链接固定格式播放当前页视频，关键点是输出的视频地址是根据后台设置加密影响的样式。如何修改如下代码

$content=str_replace("{playpage:player}","<iframe id=\"bfck\" scrolling=\"no\" frameborder=\"0\" allowfullscreen></iframe><script>var pn=pn;var forcejx1=forcejx;var forcejx2=\"no\";var forcejx3=forcejx;if(forcejx1!=forcejx2&&contains(unforcejxARR,pn)==false){pn=forcejx3;}else{pn=pn;}document.getElementById(\"bfck\").width=playerw;document.getElementById(\"bfck\").height=playerh;document.getElementById(\"bfck\").src=\"{$playerurl}\"+pn+\".html\";</script>",$content);
