Hi there TheKiller,
I suppose that depending on the context you could have a nested ternary, could be a bit tricky, depending on what would be needed, but once the logic is sorted out I would think that an appropriately nested ternary would do the job!
They are handy things to learn especially if you want to try and covert a paragraph of code into a more digestible statement.
Cheers,
MRb

You **can** "stack" ternary statements but as noted in the documentation [php.net], you have to be cautious. The example there doesn't prove the case for me, but shows the potential for confusion.

Agreed, though they can be confusing, they are also pretty useful. Sometimes having a paragraph of well structured code negates the need to condense if for 'elegance' sake - if it ain't broke, don't fix it.
Nested ternarys are just a preference of mine. I use them whenever I feel as they are the better choice in a logical way..
Cheers,
MRb

Hi Matt
i have made up with this yesterday ..
echo ($Pass == "0")?"Does not require password!" ($Pass == "1")?"Password is needed!":"N/A";
but it is giving me this error ..
Parse error: syntax error, unexpected '(' in C:\wamp\www\UT\index.php on line 223
im going to have a look at that link that rocknbil gave and see if i can come up with something :)
EDIT :
I Have looked around this reply :
With Nested ternary Operators you have to set the logical parentheses to get the correct result.
<?php
$test=true;
$test2=true;
($test) ? "TEST1 true" : ($test2) ? "TEST2 true" : "false";
?>
This will output: TEST2 true;
correct:
<?php
$test=true;
$test2=true;
($test) ? "TEST1 true" : (($test2) ? "TEST2 true" : "false");
?>
Anyway don't nest them to much....!

i came out with this two lines but they echo nothing :-?
($Pass == "0") ? "Does not require password!" : ($Pass == "1") ? "Password is needed!" : "N/A";
($Pass == "0") ? "Does not require password!" : (($Pass == "1") ? "Password is needed!" : "N/A");

here you go,
<?php
$message= $Pass==0? "Does not Require Password": ($Pass==1 ? "Password is needed!" : "N/A");
echo $message;
?>
For
Pass=0, message is "Does not Require Password"
Pass=1, message is "Password is needed!"
and for any other value of Pass it will say N/A
