The nvidia control panel does not display the principle of dynamically displaying signatures and IPs in PHP

//Contains a counter, a reminder statement, user IP and its own advertising image.
//Send a header to the browser, saying I am a picture
Header("Content-type: image/PNG");
//Define the counter here and put it in a file

if (!file_exists("Counter"))
{
for($i=0;$i<24;$i++)

The above has introduced the principle of dynamically displaying signatures and IPs in PHP, including nvidia control panel not displaying, including the nvidia control panel not displaying. I hope it will be helpful to friends who are interested in PHP tutorials.
