Question

Hi Im new to PHP so forgive the basic nature of this question.

I have a class: “CustomerInfo.php” which Im including in another class. Then I am trying to set a variable of CustomerInfo object with the defined setter method and Im trying to echo that variable using the getter method. Problem is the getter is not working. But if I directly access the variable I can echo the value. Im confused….

    <?php
class CustomerInfo
{

    public $cust_AptNum;



    public function _construct()
    {
        echo"Creating new CustomerInfo instance<br/>";
        $this->cust_AptNum = "";

    }

    public function setAptNum($apt_num)
    {
        $this->cust_AptNum = $apt_num;
    }

    public function getAptNum()
    {
        return $this->cust_AptNum;
    }


}
?>

---

<?php

include ('CustomerInfo.php');
$CustomerInfoObj = new CustomerInfo();

$CustomerInfoObj->setAptNum("22");
//The line below doesn't output anything
echo "CustomerAptNo = $CustomerInfoObj->getAptNum()<br/>";
//This line outputs the value that was set
echo "CustomerAptNo = $CustomerInfoObj->cust_AptNum<br/>";
?>

Try

echo 'CustomerAptNo = ' . $CustomerInfoObj->getAptNum() . '<br/>';

Or you will need to place the method call with in a “Complex (curly) syntax”

echo "CustomerAptNo = {$CustomerInfoObj->getAptNum()} <br/>";

As your calling a method, not a variable with in double quotes.
