How to call a php static function and pass values to it

Question

I know this might be a basic question but when I google it ,found different solutions for different php versions..in brief without wasting your time I have a. class `

class UploadHandler
{
    protected $options; 
    public static $path;

public $prop1='';  
function __construct($options=null,$x){
$this->prop1  = $x;
    $this->options = array(
        'script_url' => $this->getFullUrl().'/',
        'upload_dir' => dirname($_SERVER['SCRIPT_FILENAME']).$this->getPath(),
        'upload_url' => $this->getFullUrl().$this->getPath(),` ....and so on

AND methods inside it:

public function getPath() 
    {

return self::$path;
}

static public function setPath($autoSave)

{

self::$path = $autoSave;

}

and in another place I do this: require('upload.class.php'); .......//the above class consists inside this

UploadHandler::setPath('/files/');

why doesn't it work...??..please help me or guide me to a better tutorial

Answer 1

This works:

<?php

class UploadHandler {

    public static $path;

    public function __construct() {
    }

    public function getPath() {
        return self::$path;
    }

    static public function setPath( $autoSave ) {
        self::$path = $autoSave;
    }
}

echo '1: ', UploadHandler::getPath(), '<br />';

UploadHandler::setPath('/files/');

echo '2: ', UploadHandler::getPath(), '<br />';

?>
