Anybody care to explain?
<?php
$a = array( 'X'=>'XX', 'Y'=>'YY' );
$a['a'] =& $a;
// $b = $a;
foreach ( $a as $k) {
print $k.'<br />';
}
print_r( $a ); ?>
gives:
XX
YY
Array
Array ( [X] => XX [Y] => YY [a] => Array *RECURSION* )
--------------------
However,
<?php
$a = array( 'X'=>'XX', 'Y'=>'YY' );
$a['a'] =& $a;
$b = $a;
foreach ( $a as $k) {
print $k.'<br />';
}
print_r( $a ); ?>
outputs:
XX
YY
Array
Array ( [X] => XX [Y] => YY [a] => Array ( [X] => XX [Y] => YY [a] => Array
*RECURSION* ) )
