method_exists returning false

I am new to php oop so please bear with me...

I have a method in a class called regions that is not returning a result and when I use method_exists it say it does not exist. I can not see what I am doing wrong.

This is the class:

<?php
class SeniorMentor {
    public $regions;

    public function __toString() {

          $output = '';   
            $output .= $this->uid . "<br>";
            $output .= $this->fName . "<br>";
            $output .= $this->lName . "<br>";
            $output .= $this->email . "<br>";
            return $output;
    }

    public function regions() {
        $uid = 120;
        include 'classes/con.php';  
    $stmt = $conn->prepare('SELECT region, region_id FROM regions WHERE uid = :uid');
    $stmt->execute(array('uid' => $this->uid));

    while($row2 = $stmt->fetchAll(PDO::FETCH_KEY_PAIR)) {
     $regions = $row2;
     return $regions;
        }           
    }
}

This is the script calling it:

<?php

include 'classes/con.php';
include 'classes/SeniorMentor.php';

$uid = 120;

$seniorMentor = new SeniorMentor;

echo $seniorMentor->regions($uid);

var_dump(method_exists($seniormentor,'regions'));

$sq = $conn->query("SELECT * FROM primary_profile", PDO::FETCH_INTO, $seniorMentor);

while($row = $sq->fetch()) {

    echo "$row <br/>";
}

?>

Thanks for taking a look

if you are calling that from trait, check the caller class.

In PHP Variables are Case-Sensitive. This means the $seniorMentor and $seniormentor are two completely different variables. 

var_dump(method_exists($seniormentor,'regions'));

Should be:

var_dump(method_exists($seniorMentor,'regions'));

In most cases, I would recommend sticking with a standard naming convention to avoid this issue. The two most common are Camel Case and Delimiter Case.

Eg: Camel case $seniorMentor

Eg: Delimiter Case $senior_mentor
