ternary operator

[ngreenwood6]

I have a loop like this:

 

<?php 
for($i=0;$i<7;$i++){ 
     $class = ($i==0) ? 'cal_item cal_item_first' : ($i==6) ? 'cal_item cal_item_last' : 'cal_item';
     echo $class;
}
?>

 

I dont see anything wrong with it but for some reason when it hits the first item it is saying cal_item_last instead of cal_item_first. Any ideas?

I actually just figured it out. When I put the second statement in parenthesis it then works....Can anyone explain...I would have thought it would have stopped when it met the first condition but it seems like it was checking the second no matter what for some reason?

 

<?php 
for($i=0;$i<7;$i++){ 
     $class = ($i==0) ? 'cal_item cal_item_first' : (($i==6) ? 'cal_item cal_item_last' : 'cal_item');
     echo $class.'<br />';
}
?>

There's an example in the manual that deals exactly with this. See "Example #3 Non-obvious Ternary Behaviour" on this page.
