Bug description: reference causes foreach to fail proper iteration
Description:
------------
Using a reference to build an array, later causes foreach to fail when
reusing the reference variable name.
The bug is solved by adding unset( $element); before block B, but this
shouldn't be necessary.
Reproduce code:
---------------
// Block A - Build the Array
$a = array( 2 => array( "value" => "a" ),
4 => array( "value" => "b" ),
6 => array( "value" => "c" ) );
$b = array( "orange", "blue", "green" );
foreach( $a as $id => &$element ){
$extra = array();
foreach( $b as $color )
array_push( $extra, $color );
$element += array( 'extra' => $extra );
}
// Block B - Iterate through
foreach( $a as $element )
echo $element["value"].' ';
Expected result:
----------------
a b c
Actual result:
--------------
a b b
