PHP: Class, Objects, Methods.

[jacob1986]

I have typed some PHP code from a book (https://books.google.co.uk/books?id=KZoAq_mbhXAC&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false) page 20.

 

But keep getting an error message?

Parse error: syntax error, unexpected 'public' (T_PUBLIC)

 

PHP Code:

 

<?php

 

class MyClass {
    //class body
}

public function myMethod($argument, $another) {
    //...
}

$myObj = new MyClass();
$myObj -> myMethod( "Harry Potter");

// //let's declare a method in our ShopProduct class:

class ShopProduct {
    public $title               = "default product";
    public $producerMainName    = "main name";
    public $producerFirstName   = "first name";
    public $price               = 0;

    function getProducer() {
        return "{$this -> producerFirstName}" .
        "{$this -> producerMainName}";
    }
}

$product1 = new ShopProduct();
$product1 -> title = "My Antonia";
$product1 -> producerMainName = "Cather";
$product1 -> producerFirstName = "Willa";
$product1 -> price = 5.99;

print "Author: {product1 -> getProducer()}\n";

 

?>

myMethod is supposed to be inside the class body, like with getProducer and ShopProduct.

 

Buuut I'm pretty sure that whole class is just supposed to be a visual example. Not actual code you use.

Regarding the code it [the book] does say 'this outputs the following: author: Wills Cather'

 

Could you or maybe someone else help me to sort the code so it prints: author: Wills Cather

 

As below? Or have done it wrong?

<?php

 

class MyClass {
   $myObj = new MyClass();
   $myObj -> myMethod( "Harry Potter");
}

public function myMethod($argument, $another) {
    //...
}

 

// //let's declare a method in our ShopProduct class:

class ShopProduct {
    public $title               = "default product";
    public $producerMainName    = "main name";
    public $producerFirstName   = "first name";
    public $price               = 0;

I have rewrote the code... but this time it only prints: Author: Willa

 

It should read: Author Willa Cather

 

 

<?php
class ShopProduct {
    public $title;
    public $producerMainName;
    public $producerFirstName;
    public $price = 0;

        function __construct ( $title, $firstName, $mainName, $price) {
        $this-> title                           = $title;
        $this-> producerFirstName  = $firstName;
        $this-> produerMainName    = $mainName;
        $this -> price                        = $price;

    }

    function getProducer() {
        return "{$this -> producerFirstName}".
            "{$this -> producerMainName}";
    }
}

$product1 = new ShopProduct( "My Antonia",
                             "Willa", "Cather", 5.99);

print "Author: {$product1->getProducer()}\n";

?>

$this-> produerMainName    = $mainName;

 

You need to get a proper IDE. We can't play the human debugger forever.
