Help needed with Classes

[HPH]

I have just started to use classes and I can't recognize what is wrong with that code. It's purpose is to read templates and print them. Well this is my code:

<?php
class template_raam{
	var $templeidi_nimi;
	var $lehe_sisu;
	var $pealkiri;
	var $raamitud;

function loe_temp($path, $filename) 
{ 
	$source = join("",file($path ."/". $filename)); 


	if (strlen($source) == 0) 
	{ 
		die("Templatefaili ei õnnestud avada!"); 
	}; 

	return $source; 
}
function asenda_temp($source, $vars) 
{ 
	if (is_array($vars)) 
	{ 
		foreach($vars as $key => $value) 
		{ 
			$tag = "{VAR:" . $key . "}";  

			$source = str_replace($tag,$value,$source); 
		}; 
	}; 

	return $source; 
	$this->raamitud = $source;
} 
function valjasta()
{
	print $this->raamitud;
}
}

$dir = ".";


if($leht == "")
{
	$templeit1 = new template_raam;
	$templeit1->templeidi_nimi = "esileht.tpl";
	$templeit1->lehe_sisu = "See ongi esileht";
	$templeit1->pealkiri = "LayUp :: esileht";

$templeit1->loe_temp($dir, $templeit1->templeidi_nimi);
$templeit1->asenda_temp($templeit1->templeidi_nimi, array("pea_sisu" => $templeit1->lehe_sisu, "pealkiri" => $templeit1->pealkiri));
$templeit1->valjasta();
}
?>

and what is your question?

[HPH]

The "function loe_temp" doesn't work, it doesn't open the template file.

[thorpe]

descibe your problem. are you getting errors? what are they? what debuging attempts have you tried?

I notice a couple errors

The semicolon after the last bracket needs to be removed

if (strlen($source) == 0)
        {
            die("Templatefaili ei õnnestud avada!");
        };

Your conditional is checking if the $source is a "0" which it most likely will never be.

So you change the conditional to

if (!strlen($source))
        {
            die("Templatefaili ei õnnestud avada!");
        }

Your conditional is checking if the $source is a "0" which it most likely will never be.

I think the whole point was to check if the string length of $source was zero. Your fix is not a fix at all, and this probably isnt the problem (which the original poster still hasnt stated).

[harmor]

So "strlen" means "string length"?
I never knew that.

I think that the problem is connected with variables because when I do not use class but only it's functions then it works, but now it does't and it doesn't give me any errors at all just a blank page.
