Description:
------------
Transfer bellow code form RH Linux 2.4.20-8smp+PHP 4.4.1 (cli) 
to RH Linux 2.6.18-8.1.4e15 + PHP 5.1.6 (cli) Zend 2.1.0

In the newer system strtotime() don't return ANY result (and error too).
In the older system strtotime() return needed value.

Is it strtotime problem or wrong algorythm ?


Excuse my poor English )

Reproduce code:
---------------
$base_day="2006-06-446";
echo "bd=$base_day\n";

$real_day=strtotime($base_day);
echo "may_be_error=".strtotime($base_day)."\n";

echo "rd1=$real_day\n";


Expected result:
----------------
In the 1st system (older) echo is:

bd=2006-06-446
may_be_error=1187557200
rd1=1187557200

Actual result:
--------------
In the 2nd system (newer) echo is:

bd=2006-06-446
may_be_error=
rd1=

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

2006-06-446 is clearly not a valid date.

So, but why function don't return error value (-1) ?
 [2007-08-21 14:55 UTC] derick@php.net 
it returns false:

derick@kossu:~$ php -r 'var_dump(Strtotime("2006-06-446"));'
bool(false)

But in manual i see next:

if error occurs function return (-1). 

May be it is mistake in manual ?

No, it already says this (http://no.php.net/strtotime):

Return Values

Returns a timestamp on success, FALSE otherwise. Previous to PHP 5.1.0, this function would return -1 on failure.

Thank you !

I find mistake. MY browser show russian help page usign your link and in the russian page present old version of return value. 
In newer russian CHM helpfile  too :(.

In newer English CHM helpfile all is OK.
