php - unable to include PHPMailer in zend framework 2 -

we have code send mails using phpmailer including phpmailerautoload.php file in our php files like..

require "phpmailerautoload.php";  

and

$mail = new phpmailer; 

but syntax not acceptable in zend framework2 files, says "fatal error" "class not found". i've tried move phpmailer library folder of zf2 & include them use lib\phpmailer\phpmailerautoloadwhich zf2 standard way of including library files, doesn't work.

did work on kind, please me

lib folder not there in zend framework 2 i've added in vendor & used

use lib\folder\file;

which works, coming error..it is.,

<br /> <b>fatal error</b>:  class 'lib\phpmailer\phpmailerautoload' not found in  <b>/var/www/html/sample.php</b> on line  <b>503</b> <br /> 

it's idea add or edit stuff in vendor/ - let composer manage folder. per comment i'd suggest install phpmailer using composer instead, add:

"phpmailer/phpmailer": "~5.2", 

to 'require' section of composer.json , run composer install. suggested installation method in phpmailer's readme.

the error added question relates php not finding autoload include file. if switch composer don't need file @ can remove require line.

it's instantiate class you'd need use:

$mail = new \phpmailer; 

(note backslash), zf2 classes declare namespace @ start. backslash tells php should grab phpmailer class global namespace.
