hi,
i thinking in switch the method of $_GET["var"];
for use a global var that can be used in all program but after i talk with a friend he say that is not a secure way to use a global var
so whats the problem of using a global var and what ways are used for replace the $_GET["var"] ?
the ideia is creat a value in some part of site and them load that value without the $_GET["var"]; that can be read easily
what method that are used and secured
thanks for your help
