Bug description: explode on an empty string creates non-empty array
Description:
------------
explode on an empty string creates an array with a single blank element,
instead of an empty array (with no elements).
This means that explode/implode do not yield reversible results when an
empty array is used (though, they do otherwise -- when the array is
non-empty).
This is a duplicate of #699, but I'm resubmitting since #699 was closed
with no explanation a long time ago.
Reproduce code:
---------------
$a = array();
$b = explode(":", implode(":", $a));
print "a: ";
print_r($a);
print "<p>b: ";
print_r($b);
Expected result:
----------------
a: Array ( )
b: Array ( )
Actual result:
--------------
a: Array ( )
b: Array ( [0] => )
