Excuse me: How to specify IP and domain name crawl URL content

Ask: How to specify IP and domain name crawl URL content

File_get_contents () Such a function, can only specify the domain name or IP address crawl URL content, but if the domain name resolves to the wrong IP address, if you specify both the domain name and IP address fetch URL?

In effect, an HTTP request is sent to the specified IP address, not to the address of the DNS resolution of the domain name in the request package.
is essentially a DNS hijacking, which can be achieved through the hosts file, but modifying the hosts is too cumbersome and cannot be implemented if it is a virtual host. So I want to implement this function on the level of PHP program, ask the person!


Here is a reference scheme: http://blog.s135.com/post/389/
Use a custom function to send the constructed HTTP packet via PHP built sock connection
But it is also troublesome, I do not know whether there is a simple and efficient way: using a library function like curl, when sending an HTTP request only a multiple destination IP address


------Solution--------------------
In that case, do you use the example he gave you?


In fact, his code is also an IP attempt, not the return false, the line will get the result
------Solution--------------------
His example is the use of IP rotation, he several IP points to the same domain name,
