Hi all,
I've bumped into an interesting thing with foreach. I really don't know, if
this is normal working, or why it is, so I got curious.
The script:
foreach ( $cats as &$c ) {
echo $c['id'];
if ( $c['id'] < 5 ) {
$c['id']++;
$cats[] = $c;
}
}
Input 1:
$cats = array( array( 'id' => 1 ) );
Output 1:
1
Input 2:
$cats = array( array( 'id' => 1 ), array( 'id' => 2 ) );
Output 2:
122334455
Why is this? Is this normal behaviour?
Thanks,
Tamas
