Hi to all.
Let's say there is a class
class Box
{
var $box_title;
var $box_content;
function __construct()
{
$this->box = '';
}
function box_title($title)
{
$this->title = $title;
}
function box_content($content)
{
$this->content = $content;
}
function make_box()
{
$this->box = '<h3>'.$this->box_title.'</h3>'.$this-
>box_content;
}
function get_box()
{
return $this->box;
}
}
$box = new Box();
$box->box_title('PHP Classes');
$box->box_content('Starting with PHP 5, the object model was
rewritten to allow for better performance and more features. This
was a major change from PHP 4. PHP 5 has a full object model.')
$box->make_box();
echo $box->get_box();
This works fine.
The problem I have is how to "include" a file as box_content? it
could be plain text, but it could be a form or some kind of code.
$box->box_include(include(/path/to/file/file.php)) doesn't work, of
course.
Wrapping up the whole code in a variable doesn't make a sense too:
# file.php
$content = '
<form method="post" action="$_SERVER['PHP_SELF']">
Email = <input type=text name=email>
Pass = <input type=password name=pass>
<input type=submit value=Submit>
</form>';
# main.php
$box = new Box();
$box->box_title('PHP Classes');
include(file.php);
$box->box_content($content);
$box->make_box();
echo $box->get_box();
Also, I'm sure I read once it's not correct to print directly from
a class. First return a value/result to "main" code and then print.
Correct?

Couldn't you just do something like:
function box_content($file = NULL)
{
$content = file_exists($file) ? include($file) : NULL;
$this->content = $content;
}
It really depends what is being included (text, HTML, PHP etc).
Personally I would create a different method for each different type
as they will have to be treated and returned differently.

No. It doesn't work.
And yes, the content of the "box" could be anything.
