How to extend a class ?

[jd2007]

<?php

class Aeroplane
{
function Aeroplane($no, $type, $usage)
{
     $identity="<b>No:</b> ".$no."<br /><b>Type:</b> ".$type."<br /><b>Usage:</b> ".$usage;
 echo $identity;
}

}

class Cargo extends Aeroplane
{
function Cargo($no, $type, $usage, $goods);
{
     $identity2="<b>No:</b> ".$no."<br /><b>Type:</b> ".$type."<br /><b>Usage:</b> ".$usage."<br /><b>Usage:</b> ".$goods;
 echo $identity2;
}
}

?>

 

i want Cargo function to display all properties of Aeroplane (no, type, usage) and a additional property called goods.

what's the error you are getting?

We're not here to do you're work.

Fatal error: Non-abstract method Cargo::Cargo() must contain body in C:\AppServ\www\aeroplane.php on line 15

I think the error is bcos the base class(aeroplane) constructor is not invoked when the sub class constructor is calld.

 

Read it somwhere:

PHP 4 doesn't call constructors of the base class automatically from a constructor of a derived class. It is your responsibility to propagate the call to constructors upstream where appropriate.

Change the Class name or the function name of Cargo.

I wud like to know what PHP editor ur using...the error s comin up bcos u ve placed a ';' at the end of Cargo constructor.

function Cargo($no, $type, $usage, $goods);
