I apologize in advance for probably an absurd and not very well-posed question, just in php I'm full 0.
So the essence of the question:
there is a certain html page divided into three parts (it seems that this is called a tray if I am not mistaken), each of these parts corresponds to a .php file. In the admintray.php file (central part of the html page) I insert a link, here is the code:
print("<p><b><a href='http://ip_адрес/cgi-bin/qstat.pl'><img src='1.jpg' alt='' border='0' /><br>Череповец</a></b></p>");
The link appears, the transition occurs, but the page to which the transition is made opens as if in one part of the page with which the transition was made (in the admintray in general), in general, I remain on the page on which it was. How to make a "full" transition?
