Description:
------------
if you try to do intval on the following string:
$str_value='09123456789';

you receive the following: 2147483647



Reproduce code:

	$str_value='09123456789';

	echo "str_value -> $str_value<BR>";

	$num_value=intval($str_value);
	echo "num_value -> $num_value<BR>";


Expected result:
----------------
$num_value = 9123456789

Actual result:
--------------
$num_value=2147483647

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. 

Thank you for your interest in PHP.

Read about octal numbers and type-juggling here: http://www.php.net/manual/en/language.types.integer.php

Yet you'd expect intval to return decimal number and not octal (!!). The default intval base is 10.

Try the same script with $str_value='0912345678';
and $str_value='09123456789' to see the difference;
