After using print_r() on an array, the array pointer isn't reset.  Affects 4.0.3pl1 and 4.0.4 CVS.

$arr['a'] = 'Apple';
$arr['b'] = 'Banana';
$arr['c'] = 'Corn';

print_r($arr);
//reset($arr);

while(list($k,$v) = each($arr))
   echo "$k => $v\n";

In retrospect, the proper thing for print_r to do would be to preserve the array's internal pointer, rather than reset it.

This patch seems to do the job.

Automatic comment from SVN on behalf of googleguy
Revision: http://svn.php.net/viewvc/?view=revision&amp;revision=328776
Log: Removed mention of print_r reseting array's internal pointer. This is not the current behavior. See bug #8289 for more information.
