print_r($data) results :

Array
(
[item] => Array
(
[stats] => Array
(
[0] => Array
(
[Date] => 05/23/2007
[ProgID] => 12
[Info] => 12
)

[1] => Array
(
[Date] => 05/01/2006
[ProgID] => 21
[Info] => 11
)

I tried using :

foreach ($data['item']['stats'] as $x)
{
echo $x['ProgID'];
}

It works fine as long as stats array has more than 1 array, but if the
structure is :

Array
(
[item] => Array
(
[stats] => Array
(
[0] => Array
(
[Date] => 05/01/2006
[ProgID] => 12
[Info] => 12
)

Using same foreach loop, it shows wrong data.

Any ideas ?

Thank you for your interest in PHP.

If you still think, that this is a bug, please minimalize your script,
so that you can just reproduce the bug and then reopen the report.

Please take also into concideration, that the bug might already be
fixed in a more current version of PHP.

Thank you.

Noticed the errors not in foreach, but in the pass. PHP kills the outer
array if theres only one element in it in a pass. Thats still a bug.

I have code that traps all errors in a multidimentional array. The
array is structured so each row has a numerical key (ie $errors[] =
array('err_code'=>12, 'err_file'=>'happy.php');). You get the
idea. For
error handling I have a function within a class that will accept an
error array and do output based on it. The function is as follows:

function pass_err_row($errors, $default_val=NULL, $override_val=NULL) {
// Throw errors based on err_file or default
	if (is_null($default_val))
{$default_val=PATH_TO_ROOT.LOC_ERROR."DEFAULT/errors.php";}
	if (!is_null($override_val)) {
		foreach($errors as $error_row) {
			include($override_val);
		}
	}
	else {
		foreach($errors as $error_row) {
			if ($error_row['handle_file']!==FALSE &&
$error_row['handle_file']!=="") {
				include($error_row['handle_file']);
			}
			else {
				include($default_val);
			}
		}
	}
}

This works great as long as the array passed has more than one error
(each error being another array) in it. So if $errors[0] and $errors[1]
both exist, everything works. Where it gets really wacky is if only
$errors[0] exists then the foreach loops results in very strange
results. Each error array row in $errors consists of the following 8
indexes:
'err_no', 'err_text', 'err_file', 'err_line',
'system_err',
'handle_file', 'handle_code', 'severity'.
What happens is the foreach loops 8 times with $error_row being equal
not to the array in $errors[0] but being equal to an value in the sub
array. So the first result would be the equivalent of
$errors[0]['err_no']'s value. $errors is still an array, so why would
the for each instead use the sub array? very weird.
