How does the forum signature display the other party's information?

This question is a call. Use code.

There is also code for PHP to display IP signature pictures.

The code is as follows:

& lt？ Header ("content-type: image/png");

//Note that none of the following content supports Chinese unless you write it in utf-8.

if(getenv(" HTTP _ CLIENT _ IP "){

$ IP = getenv(" HTTP _ CLIENT _ IP ")；

$ip_agent = getenv ("remote _ addr");

} else if(getenv(" HTTP _ X _ FORWARDED _ FOR "){

$ IP _ real = getenv(" HTTP _ X _ FORWARDED _ FOR ")；

$ip_agent = getenv ("remote _ addr");

} Otherwise {

$ip_real = getenv ("remote _ addr");

$ ip _ agent =

}

//The above is the real IP of the extracted browser.

$ User = getenv(" HTTP _ User _ AGENT ")；

if(eregi("Windows[[:space:]]98 "，$User)) {

$ User _ Agent = " Windows 98

}

else if(eregi(" Win[[:space:]]9x[[:space:]]4.90 "，$User)) {
