Sorry bro,
was thinking that in the initialization section that it would run the
count again, but that is not the case...
$max is initialized first and never looked at again during the for
loop...

If you reed the code carefully, it first assigns $x=1 and
$max=count($myArray),
then it compares $x with $max

Then only problem with doing it like
for($x = 1, $max = count($myArray); $x <= $max; $x++ )
is that the $max = count( $myArray ) is always verified in each
loop...slowing the for loop down...
faster to do
$max = count( $myArray );
for( $x = 1, $x <= $max; $x++ )
just my $0.02...for the day...
the most correct way is probably:
$size = sizeof($myArray);
for( $x = 1; $x <= $size; $x++ ) {}
But, this is too personal and is "my way".

The first one is better, and, besides that - it is the most correct way
- there might be something making the array change while inside the loop
- thus you have to do some extremely high calculations to understand the
array does not change runtime, which makes it useless.
Simply do the "elegan
As max($myArray) may potentionaly change, it is evalueted everytime (you
may do
$myArray[]=$big_number in your loop). So if you know it is not going to
change, use the first way.
