I'm trying to understand/debug a bit of PHP, the code is as follows:-
if (isset($data['date']))
{
if (is_array($data['date']))
{
foreach($data['date'] as $key => $date)
{
$date = $this->_convertDate(trim($date));
if (!$date) unset($data['date'][$key]);
else $data['date'][$key] = $date;
dbglog($data, "Converted data");
}
}
else
{
unset($data['date']);
}
}
What's happening is that it always ends up with nothing in $data
(what's reported by that dbglog()).
I'm confused by what happens with that foreach as, as far as I can
see, $data['date'] is just what I would call a list in python, it's
not an array indexed by values it's just a sequential array.
So, in the foreach loop $key gets the values from the $date array and
$date is empty (confirmed by further dbglog()).
Am I understanding this right? If I create an array:-
$aa = array('abc', 'def', 'ghi', 'jkl');
Then do:-
foreach $aa as $x => $y
{
// what do I get for $x and $y here?
}
Sorry this is a bit confused/muddled, I'm definitely not a PHP programmer.
