Calculation with DateTime class causes php range() error...
Possibly a bug?

Insert a simple DateTime calculation with DateTime::diff() in the index action of the default tutorial yii application.

Astonishing is that it causes an php range() error when you change from the home view to the contact view.

It also seem that the more often you call the diff() the greater is the chance to get the error. In other words the more often you recall the home view the greater is the chance to get the error when you switch to the contact view.

Here the code:

date_default_timezone_set('Europe/London');
//Aktuelle Zeit als DateTime
$dakt = new DateTime("2011-10-15 10:45:00");
//Endzeit Zeit als DateTime
$dend = new DateTime("2011-10-15 10:00:00");

$intv = $dakt->diff($dend);


OS: Windows XP
Yii: 1.1.8.r3324
XAMPP for win: 1.7.4

Why you provide Yii version ?

it is not Yii class, it is php class

check this out http://php.net/manua...tetime.diff.php

DateTime is very strict in the date format You give it...
also put attention to echo $interval->format('%R%a days');

I do not find any error in the use of DateTime.
I test with:

<?php

date_default_timezone_set('Europe/London');
//Aktuelle Zeit als DateTime
$dakt = new DateTime("2011-10-15 10:45:00");
//Endzeit Zeit als DateTime
$dend = new DateTime("2011-10-15 10:00:00");

$intv = $dakt->diff($dend);

echo 'Zeit1: ' . $dakt->format('Y-m-d H:i:s') . "<br>";
echo 'Zeit2: ' . $dend->format('Y-m-d H:i:s') . "<br>";

echo $intv->format('%H:%I:%S') . "<br>";

?>

Result printed is correct:

Zeit1: 2011-10-15 10:45:00
Zeit2: 2011-10-15 10:00:00
00:45:00


but used with yii described as i mention above i got a php error...

I have the same problem, with Yii 1.1.6 version. When i use DateTime diff. Please any solutions idea?

[Ivan Ozercov]

I have this problem too. Yii 1.1.9 version.

Ran into the same problem. Seems to be platform dependent, according to this: code.google.com/p/yii/issues/detail?id=2317. It happened for me on WAMPSERVER with PHP 5.3.0 and Apache 2.2.11. The problem went away when I switched to PHP 5.3.13 on Apache 2.2.22. The 4th comment on the above linked bug report suggests a solution which worked on the older version, but was not necessary on the more recent one.
