The reason it won't work is this: each element in the $_POST array has a
key which is specified along with the arguments passed to the page. Unless
one of those keys is 0 or '0' there just won't be a $_POST[0]. See this
extract from the PHP help file / manual:
$a = array( 'color' => 'red'
, 'taste' => 'sweet'
, 'shape' => 'round'
, 'name' => 'apple'
, 4 // key will be 0
);
In the above example there is an $a["sweet"] but no $a[1] (I have run it
and checked!). There is only an $a[0] because 0 is the next default key to
be associated with any value assigned to the array. If you create an array
like this:
$a = array(0 => 'Fred', 4 => 'Jim');
...there will be an $a[0] and $a[4] but no intervening $a[1] to $a[3]
Arrays in PHP are associative arrays - a sort of list of key/value pairs.
Unlike arrays in C or BASIC, they don't have a range var[0] to var[max]
unless you assign values without a key. The only way to iterate through the
values is with foreach() or each()
