Fatal error: Call to undefined function msgpack_pack()

[ronaldo-systemar]

I got this .dll/binary that matches my current php version, load works, as you can see (phpinfo()):

MessagePack Support enabled
Session Support enabled
extension Version 0.5.5
header Version 0.5.4

Directive Local Value Master Value
msgpack.error_display On On
msgpack.illegal_key_insert Off Off
msgpack.php_only On On

But when I try to to call msgpack_pack() i got a fatal error telling me the function does not exist.

Link of .dll: http://windows.php.net/downloads/pecl/releases/msgpack/0.5.5/php_msgpack-0.5.5-5.5-ts-vc11-x64.zip

PHP version is 5.5.12 running on windows

I fixed it. Composer not loading the extension cuz it's no stable. If someone get this issue, it's easy to fix, put the following in your composer.json:

"minimum-stability": "dev",

"prefer-stable": true,**

"require": {
     ...
},
