Bug description: in_array returns the wrong result with long strings
Description:
------------
I tried to check if a value existed in an array, but in_array did not
return what I expected when I'm dealing with large strings (18 chars or
longer).
I have PHP 5.0.1 compiled with Apache 2.0.50 and DBG v2.11.26 running;
Reproduce code:
---------------
<?php
$needle = '123456789012345671';
$arrayA = array('123456789012345672'); // check number is different
var_dump(in_array($needle, $arrayA)); // the correct output is FALSE,
but TRUE is printed
?>
Expected result:
----------------
bool(false)
OBS: $needle does not exists in $arrayA (last number is different), that's
why it should return FALSE.
Actual result:
--------------
bool(true)
Notes: when the value of the variables are letters, in_array works fine
with the same quantity of chars.
i.e:
<?php
$needle = 'abcdefghijklmnopqr1';
$arrayA = array('abcdefghijklmnopqr2'); // last char is different
var_dump(in_array($needle, $arrayA));
?>
