I´m trying to use or operator in a php sentence but only validate the first condition, what´s wrong?
if ($_SESSION['user_id'] != 4 || $_SESSION['rol'] != 1)
{
//exit
}else{
//do something
}```
You should invert the condition in this way:
if ($_SESSION['user_id'] == 4 || $_SESSION['rol'] == 1)
//it's ok
else
//exit
Because otherwise if the user_id is 4 it will otherwise fail if it doesn't have the role expected
