Hello!
The following PHP code:
<?
$a = array("1"=>"First Element", "2"=>"Second Element");
$v = &$a['3'];
print_r($a);
?>
has this result:
Array(
1 => First Element,
2 => Second Element,
3 =>
)
Can anyone give me an explanation for this? What is happening in the guts of the PHP interpreter when it gets these instructions?
With best regards
Gabriel Birke
