error_reporting(E_ALL);
$var = '12345678901234567890';
settype($var, 'int');
echo $var;
?>

Yes, the documentation in this needs a cleanup. I found this page better explaining what happens and when/why:

http://www.php.net/intval

The http://www.php.net/manual/en/language.types.integer.php page
requires some care too, it's too long. (split/add urls to topics, whatever...)

or the Expected result should be:

1.2345678901345678e+17

Sorry i'm confused with float.

1.2345678901345678e+17 isn't the same integer as 12345678901234567890.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"Maximum value for "int" is PHP_INT_MAX."
