Objects, Headers, Printing Content...

mreider

Hi. I am learning PHP - I used to be a ColdFusion developer so it is close enough for me to be a quick study.

Anyhow, I was messing around with objects today. I want to print pages dynamically from an object.

Here's the deal:

My index.php page looks like this:

<?php
include("functions.php");
$content = new DynoPage("home page");
$content->showContent();
?>

My functions.php page looks like this:

<?php
Class DynoPage
{var $pageKey;
var $resultPage;
function DynoPage$pageKey)
{
$this->pageKey = $pageKey;
}

function showContent()
{
$this->resultPage == '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>' + $this->pageKey + '</title>
</head>
<body> etc... </body>
</html>';
return $this->resultPage;
}
}
?>

When I browse my index.php page I get this back from the apache server:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html; charset=iso-8859-1"></HEAD>
<BODY></BODY></HTML>

Why is Apache sending a this HTML without my permission and why isn't my content showing up as expected?

Thanks for your help - sorry if this is an amatuer question.

Look like you used == instead of = in the showContent() function ... ?

Also, it does not look like you are actually printing the contents. Need:
echo $content->showContent();

First of all, thanks for responding to me. I appreciate your help.

Unfortunately, I am still getting bad results. Let me paste what I have and explain what it now yields.

first page is index.php:

<?php

include("functions.php");
$content = new DynoPage("hola");
echo $content->showContent();

second page is functions.php:

<?php
Class DynoPage
{var $pageKey;
var $resultPage;
function DynoPage$pageKey)
{
$this->pageKey = $pageKey;
}

function showContent()
{
$this->resultPage = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>' + $this->pageKey + '</title>
</head>
<body> etc... </body>
</html>';
return $this->resultPage;
}
}
?>

This returns a '0'

Thanks again for your patience, I am sure this is something very silly - and I hate to store silly things in the phpbuilder forum database. But maybe you'll catch it - I can't seem to.

Well, first thing that comes to mind when looking at "what you have now" is that you should use a concatenation operator (.) rather than an addition operator (+) when adding characters to a string.

In the PHP CLI,

<?php

$this="This is a stri"+"ng!";

echo $this;

echo "\n";

?>

also yields

Also, don't worry too much about storing "silly things" in the PHP Builder.com db. I looked at the path on this one, and we're in the "newbies" forum -- and, IIRC, we were all newbies once upon a time... 😉

It is all better now. Newbies UNITE!

Now onto dynamic functions...
