PHP file_get_contents和CURL无法获取基于javascript的页面的内容

I have tried both file_get_contents and CURL to fetch the content of a specific page. I setup the CURL to follow redirects and changed User-Agent, however, it did not work. I have no problem when loading page in browser. I get a page with below code whenever I try to fetch it with file_get_contents or CURL:

 <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Loading ...</title> <script 
src="/jquery.js" type="text/javascript"></script> </head> <html> <noscript>Enable java!</noscript> <div id="status"></div> <script type="text/javascript"> 
function check(){ $.ajax({
    type: "POST",
    url: "/index.php",
    data: "allowed=5b91b80a061537ae6a23835aba38279e",
    success: function(html){if(html == "allowed"){location.reload();}},
    beforeSend:function(){
        $("#status").html("Loading ...")
    }
});
}
$(document).ready(function(){
    check();
});
</script> </html>

Is there anyway to bypass such restriction without using Javascript based Web Scrapers like PhantomJs, CasperJs or ZombieJs? Simply using a plain PHP?
