Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
The third parameter for substr() is the number of characters to return, not the
end position.

Description:
------------
the substr(string,from,to) failed and return something i find strange, and never seen it before..
my version is also 5.3.5 but i chose 5.3.6 because the 5.3.5 is not there.
Test script:
---------------
$x=1;
while ($x<=strlen("hello"))
{
$xx=$x-1;
echo substr("hello",$xx,$x);
$x++;
}
echo "<br/>";
$x=1;
while ($x<=strlen("hello"))
{
$xx=$x-1;
echo $xx." ";
echo $x." ";
echo substr("hello",$xx,$x);
echo "<br/>";
$x++;
}
Expected result:
----------------
i expect a result saying:
hello
0 1 h
1 2 e
2 3 l
3 4 l
4 5 o
like in substr("hello",0,1) substr("hello",1,2) and continue like that.
Actual result:
--------------
the actual result is:
hellloloo
0 1 h
1 2 el
2 3 llo
3 4 lo
4 5 o
like substr("hello",1,2) is "el" how can that be?
and substr("hello",2,3) is "llo" and how can that be too?
