using $this when not in object context

[purefan]

Hello guys!

Im coding a new project and ran into this very odd error, the output says:
Fatal error: Using $this when not in object context in C:\wamp\www\ChessRPG\inc\template.inc.php on line 23


I tried a work around, at that time it was possible to just assign the final value to the variable but more errors like this started to show up, so think I should get this cleared out before going on to redesign the whole project. I have commented above the two lines that I know show this same error:

<?php
/**
*@author purefan
*/

class Template
{
    // Attributes
    // the path to the templates
    var $path = "templates/";
    // the file name we're fetching
    var $_file = "";
    // the array of changes to be applied to this fileName
    var $_changes = array();
    
    
            // Functions
    function Template()
    {}
    
    function loadTemplate($section = "", $fn)
    {
        // this next line is error number 1
        $filename = $this->path;
        $filename.=$section.$fn;
        if(file_exists($filename))
        {
                $fr = fopen($filename,"r");
                $this->_file = fread($fh, filesize($myFile));
                return true;
        }
        return false;
    }

    function setChanges($arr)
    {
        $this->_changes = $arr;
    }
    
    function applyChanges()
    {
        if($this-_file != "")
        {
            foreach($this->_changes as $from => $to)
            {
                $this->_file = str_replace("{%".$from."%}", $to, $this->_file);
            }
            //$this->_file = str_replace("{".$from."}", $to, $this->_file);
        }
    }
    
    function prnTemplate($isReturn = false)
    {
        if($isReturn){
            return $this->_file;
        }
        else
        {
            // this other line shows another error like before
            echo $this->_file;
        }
    }
}
?>

The project is running on a PHP5 server (its actually WAMP) in case this helps...

Ive looked around but the obvious replies have been what the error itself suggests, that $this is being used in a non object context, but I just want to access the attribute like ive done always before, dont know why this time it isnt working...

Thanks for your time

Are you accessing the class statically?

function applyChanges()
    {
        if($this-_file != "")

Bokeh!!!
you are a marvel! I actually was and when I instantiated it we're back on track :smile: Thank you so much!

Thanks to you too MrCoder!!, this was also a miss from me

function applyChanges()
    {
        if($this-_file != "")
