How can I specify the order that an Array() is imploded? See code below:
<?php
$toImplode = Array(
1 => "Second",
0 => "First",
2 => "Third"
);
$finalString = implode(" - ", $toImplode);
echo "<p>" . $finalString . "</p>";
/* Results as "Second - First - Third"
* But I need it to be "First - Second - Third"
*/
?>

Do a ksort( $toImplode ); before the implode. (See
http://de.php.net/manual/en/function.ksort.php)

Thanks... suppose the keys are not in a sortable order, like this:
$toImplode = Array(
"second" = "Second",
"fourth" = "Fourth",
"third" = "Third",
"first" = "First"
);
Or would I need to simply:
echo $toImplode["first"] . $toImplode["second"]; // etc.

Use usort() and define your own comparison function.
Or you could just use the individual elements as you indicated. There
is no rule you have to use implode().

Rather u*k*sort() for sorting by keys:

See the marked part.
You should also post the (manual) URI that works best for the person using
it, which would be
<http://php.net/uksort>
in this case.

This is not PHP code.

No, aside from u(k)sort() you can use a loop to build a new array:
$a = array();
foreach (array('first', 'second', 'third', 'fourth') as $key)
{
$a[] = $toImplode[$key];
}
echo implode(',', $a);
