Zend_Http_Client Header with integer value throws exception

[cliffordwhansen]

I just updated to 1.12.12 using composer and got the following error:
Fatal error: Uncaught exception 'Zend_Http_Exception' with message 'Invalid header value detected' in /vagrant/vendor/zendframework/zendframework1/library/Zend/Http/Client.php on line 1597

After some debugging I found the following fixes it

diff --git a/library/Zend/Http/Client.php b/library/Zend/Http/Client.php

+        if (!(is_string($value)||is_integer($value)) && (! is_object($value) || ! method_exists($value, '__toString'))) {
             require_once 'Zend/Http/Exception.php';
             throw new Zend_Http_Exception('Invalid header value detected');
         }

My PHP version.

Hotfix!!!
replace string 1595
from: if (! is_string($value) && (! is_object($value) || ! method_exists($value, '__toString'))) {
to: if (! is_string($value) && ! is_numeric($value) && (! is_object($value) || ! method_exists($value, '__toString'))) {

P.S. Who make pull request? )

PR #567 is ready to go. Hopefully we'll roll out 1.12.13 later today.
