oop - PHP Fatal error Call to private Uploade::__construct() from invalid context (Construct is Public) -

the problem i'm having strange one, log file says __construct method in class called 'upload' private, in reality public! error makes no sense. class code;

class upload {      public $errors;      public $imagetypes;     public $cdn_url;     public $uploadpath;     private $maxheight;     private $maxwidth;     private $maxtokenlength;     private $forcemaxdimensions;     private $maxfilesize = 5;       public function __construct()      {         include_once 'config.php';          $this->imagetypes = array('jpg', 'png');         $this->errors = array();          # convert megabytes bytes         $this->maxfilesize = $this->maxfilesize * 1048576;     } } 

this how initiate class;

include_once 'upload.php'; $upload = new upload; 

this error log file;

php fatal error:  call private upload::__construct() invalid context 

i've looked @ many answers online , non have helped me, i'm hoping answer stackoverflow! help.

edit: contents of config.php file

$imagetypes = array('jpg', 'png'); $cdn_url = 'cdn.php'; $uploadpath = 'uploads/'; $maxheight = 1000; $maxwidth = 1000; $forcemaxdimensions = true; $maxfilesize = 5;// mb 

based on code posted, mentioned error can't happen.

i propose use cstatementtracer found in my answer question.

cstatementtracer uses php's tick-feature trace each executed statement , dump log file. said, need enable cstatementtracer somewhere in application.
