Description:
------------
http_build_query truncates large integer keys to 12 digits regardless of them 
being passed as a string, integer, or float. 

However if the integer value is cast to a string and appended with non-integer 
characters the key is not truncated.

Test script:
---------------
$var = 1234567890123
echo http_build_query($var);

$var = (string)1234567890123
echo http_build_query($var);

$var = (float)1234567890123
echo http_build_query($var);

$var = "1234567890123.asd"
echo http_build_query($var);

Expected result:
----------------
Array([0]=>1234567890123)
Array([0]=>1234567890123)
Array([0]=>1234567890123)
Array([0]=>"1234567890123.asd")

Actual result:
--------------
Array([0]=>123456789012)
Array([0]=>123456789012)
Array([0]=>123456789012)
Array([0]=>"1234567890123.asd")

Also I do want to mention that I saw the previous bug report on this issue

http://bugs.php.net/bug.php?id=49023

However this bug report has been labeled "bogus" even though the documentation 
does not support the mentioned behavior.

You need to use:

$var = array('12345678901' => 'foo');
var_dump(http_build_query($var));

As said in the other bug report.

Your example does not represent the problem. In my haste I messed up my own 
example code but here it is again.

$var = "1234567890123";
$varArray = array();
$varArray[$var]= "foo";
$build = http_build_query($varArray);
$result = array();
parse_str($build, $result);
print_r($result);

//Expect Array( "1234567890123"=>"foo")
//Actual Array( "123456789012" =>"foo")

I got the expected result...

Array
(
    [1234567890123] => foo
)

Cannot reproduce the issue either.

PHP Version 5.2.4-2ubuntu5.10

Here is another test case

$test = array('123456789012345=>'9780553', 1=>12312312312);
print_r($test) //This line looks correct
echo http_build_query($test) //This line does not

Here is the output
Array ( [123456789012345] => 9780553 [1] => 12312312312 ) 
123456789012=9780553&1=12312312312
