Re: isset
In PHP, every variable begins with a $, so $mod is a variable, but isset($mod) is not a variable, it merely tests whether any value has been set in the variable $mod. As such, the function returns a True or False, depending on whether $mod has been set to a value.jreategui wrote:Hello people i 'm newbie in PHP world, i haver some experience in other languages but this is my first one on PHP.
