Initating an Array inside a Class - php

Question

I have been having a hella of a time trying to get an array to initialize inside a class. What I am trying to attempt is to create a side menu using an array and a child class. I have tried to solve this problem for several days and now I'm asking for help. I have a feeling I am missing something basic as I am just learning PHP.
Below is my code and the commented out lines are attempts at a solution that have not worked.
<?php
/************* global variables ******************************/
//global $house_array, $car_array, $vacation_array, $company_address;
$company_name = "Heaven HVAC";
$street = '12345 Blue Canyon Rd.';
$company_citystatezip = "Heaven, CA 91777";
/************* end global variables **************************/
echo '<H1 align="center">Calling Array inside Child Class</H1>';
class Company{
//// insert object variables (properties) HERE
var $company_url = "http://localhost";
var $company_email = "example#example.com ";
//// insert methods here
function getHeader($company_name, $color) {
$topheader = "<TABLE align='center'; style='background-color:$color; width:50%'><TR><TD>";
$topheader .= "<H1 style='text-align:center'>$company_name</H1>";
$topheader .= "</TD></TR></TABLE>";
return $topheader;
}
function getFooter($color) {
$this->address;
$bottomfooter = "<TABLE align='center'; style='background-color:$color;width:50%'><TR><TD>";
$bottomfooter .= "<center><b><u>$this->address</center></b></u>";
$bottomfooter .= "</TD></TR></TABLE>";
return $bottomfooter;
}
} // end class Company
//// Working On child class - If commented out, then the code has been tried and failed
class AirCondition extends Company {
var $navbar_array;
//// create array
function create_navbar_array ( ) {
$mainurl = $this->company_url;
$this->navbar_array = array( "Home Page"=>"$mainurl?whichpage=home", "Sales"=>"$mainurl?whichpage=sales",
"Support" => "$mainurl?whichpage=support", "Contacts" => "$mainurl?whichpage=contact" );
}
//create_navbar_array();
// return $navbar_array;
function getLeftNavBar($array){
// create_navbar_array();
## Create a table to display arrays
print "<TABLE BORDER='1'>";
echo '<tr><td>Navigation Menu</td></tr>';
foreach($array as $Page){
echo "<tr><td>{$Page}</td></tr>";
return $array;
}
echo "</TABLE>";
}
}
$HVACcompany = new AirCondition();
$HVACcompany->address = "777 Estate Rd <br /> $company_citystatezip";
echo $HVACcompany->getHeader($company_name, orange);
echo "<br/>";
echo $HVACcompany->getFooter(green);
//echo $HVACcompany->getLeftNavBar();
//echo $HVACcompnay->create_navbar_array();
//$HVACcompnay->create_navbar_array();
$HVACcompany->getLeftNavBar($navbar_array);
?>
I am able to create the web page layout, but the array isn't initializing. What am I doing wrong/missing?

Answer 1

The following line:
$HVACcompany->getLeftNavBar($navbar_array);
should be:
$HVACcompany->getLeftNavBar($HVACcompany->navbar_array);
Because $navbar_array was never declared in the global namespace, however it was declared as a public variable within the class AirCondition which was initialized with the variable $HVACcompany.
Additionally you need to call the function $HVACcompany->create_navbar_array();
before calling $HVACcompany->getLeftNavBar($HVACcompany->navbar_array); in order to create the array $navbar_array.
Also remove the return $array; statement inside the foreach loop.
