if end of array in loop help

[MDanz]

How do i do if i've reached of array?  i know i could do end of loop.  but the array is present many times in my code.

 

while($row = mysql_fetch_assoc($getdetails)) {
$people = $row['people'];
$_SESSION['people'][] = $people;

    if(end($_SESSION['people'])) {
    //code

    }
}

I'm not entirely sure what you're asking, can you try reforming the question?

$_SESSION['people'] is an array.  I add to $_SESSION['people'] by doing this...

$_SESSION['people'][] = $people;

 

basically how do i code "if last key in array?"..

 

i tried this but it's not correct

 if(end($_SESSION['people'])) {
    //code

    }

nvm.. i got the solution

 

end($array);
$lastKey = key($array);
