Hi,
While programming I stumbled across this - can anyone reproduce this, or is it
just a bug in my system? Replacing the $currtag in the final foreach loop with
&$currtag causes it to behave as expected, but the code as pasted below is
obviously badly dysfunctional. Is anyone able to shed some light on this?
Cheers,
Steve
-------------------------------------
<?php
$tags = array(
'Item1',
'Item2'
);
foreach($tags as &$currtag) {
$currtag = array($currtag, 0);
}
print_r($tags);
foreach($tags as $currtag) {
print_r($tags);
}
?>
----------------------------------
That code gives the following output:
Array
(
[0] => Array
(
[0] => Item1
[1] => 0
)
[1] => Array
(
[0] => Item2
[1] => 0
)
)
Array
(
[0] => Array
(
[0] => Item1
[1] => 0
)
[1] => Array
(
[0] => Item1
[1] => 0
)
)
Array
(
[0] => Array
(
[0] => Item1
[1] => 0
)
[1] => Array
(
[0] => Item1
[1] => 0
)
)
