I am using couchbase PHP Sdk to query some data and they made some changes from version 2.x to 3.x. Before i could get some metrics easily now I get the error> It complains that I cant access private value.

Uncaught Error: Cannot access private property Couchbase\QueryResultImpl::$meta

First of all, I am sorry I didn't use couchbase PHP , but here is how you can create a Getter and Setter method for a Private variable, hope you can implement it

<?php

class Student {
    private $sName;

    public function setName($name) {
        $this->sName = $name;
    }

    public function getName() {
        return $this->sName;
    }
}

$student = new Student;                     // create an object
//$student->sName = "error";                // this makes an error while it is Private: Fatal error: Uncaught Error: Cannot access private property
//echo $student->sName;                     // this makes an error while it is Private: Fatal error: Uncaught Error: Cannot access private property
$student->setName("MisterniceGuy"); // Set student name
echo $student->getName();                   // MisterniceGuy

?>
