Bug description: explode() returns weird array on string that starts with
delimiter
Description:
------------
When explode() explodes a string that starts with the delimiter, it
returns an array that confuses reset(). The array is not empty, but
reset()ing it returns FALSE.
The same thing happens with split().
This messes up when you try to iterate over the result like this:
for($i = reset($array);$i;$i = next($array) { ... }
Reproduce code:
---------------
$array = split(',', ',a,b,c');
echo count($array) . "Count is \n";
if(reset($array) == FALSE) echo "Can't happen.\n";
Expected result:
----------------
If I understand the semantics of reset() correctly, it should only returns
FALSE on empty arrays. The array above is clearly not empty (count($array)
returns 4), so resetting it should not return FALSE.
Actual result:
--------------
The above script prints out this when run:
Count is 4
Can't happen.
