http_build_query doesn't handle 64-bit integers even on 64-bit systems, truncates to 12 digits only.

Reproduce code:
From manual page: function.http-build-query

$args = array("test" => 100000012859481);
$output = http_build_query($args);

Expected result:
string(17) "test=100000012859481"

Actual result:
string(17) "test=100000012859"

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at and the instructions on how to report
a bug at

Pass the value as a string or as a float. The truncation is actually 
done by PHP, during array creation, not by the http_build_query()

Can you please produce the line in documentation explaining your statement? I can find no mention of sensitivity to the types used in the formdata parameter.

formdata: "[m]ay be an array or object containing properties.")
