If I have an array:
$nav = array($nav_1, $nav_2, $nav_3);
and want to check if they are empty with a loop (the real array is much bigger), so that it checks each variable separately, how do I do it?
I want something like this;
$count = 0;
while(count < 3){
if(empty($nav[$count])) //the loops should go through each value (nav[0], nav[1] etc.)
//do something
$count = $count+1;
}else{
//do something
$count = $count+1;
}
}
