Description:
------------
When using foreach and looping through an array the second time if the
index variable isn't unset the results are that the referenced variables
is used as the index rather than the named variable.
The issue can be solved if when the foreach is set up that it does an
unset on the variable passed as the "as" variable. PHP should be changed
to unset the parameter passed as the index into the array.
Reproduce code:
---------------
$myarray = array("one","two","three","four");
foreach ($myarray as &$x) {
$x = "$x -";
print "$x\n";
}
print "\n";
foreach ($myarray as $x) {
print "$x\n";
}
Expected result:
----------------
one -
two -
three -
four -
one -
two -
three -
four -
Actual result:
--------------
one -
two -
three -
four -
one -
two -
three -
three -
