简单的PHP错误：语法错误，未完成的类声明

Question

I get two errors and I dont know how to fix this.

I get the error "syntax error, unfinished class declaration" at the line:

private $language;

I get "syntax error, unexpected 'public', expecting 'EOF'" at the line:

public function getCurrencies()

This is the whole code:

class Driver extends Driver{

public static $url = "http://www.com/";
/* The method of posting data to the website */
public static $method = "GET";
/* The part of the url extending the domain name until the search term */
public static $url_searchbase = "search/searchresults.aspx?N=0&Ntt=";
/* The part of the url entailing the search term, deifining additional paramters */
public static $url_searchtail = "&Ntk=Primary&i=0&sw=n&ps=9999&pn=1";
private $currency;
private $language;
/* Allowed currencies */
$currencies = array("USD", "CAD");
/* Allowed languages */
$languages = array("ENU");

function __construct($currency, $language){
    if(setCurrency($currency) AND setLanguage($language)){
        return TRUE;
    } else {
        trigger_error("Currency '". $currency ."' or Language '". $language ."' not supported.", E_USER_ERROR);
        return FALSE;
    }
}

/*
 * Return an array of allowed currencies
 */
public function getCurrencies(){
    return $currencies;
}

/*
 * Set the currency
 */
function setCurrency($currency){
    if(in_array($currency, $this->$currencies)
    {
        $this->$currency = $currency;
        return TRUE;
    } else {
        trigger_error("Currency '". $currency ."' not supported.", E_USER_ERROR);
        return FALSE;
    }
}

/*
 * Return an array of allowed languages
 */
public function getLanguages(){
    return $languages;
}

/*
 * Set the language
 */
public function setLanguage($language){
        if(in_array($language, $this->$languages)
    {
        $this->$language = $language;
        return TRUE;
    } else {
        trigger_error("Language '". $language ."' not supported.", E_USER_ERROR);
        return FALSE;
    }
}

}

Answer 1

class Driver extends Driver makes no sense. I think you got one of the names wrong.

Also, you cannot put real code outside of a function.

Move

/* Allowed currencies */
$currencies = array("USD", "CAD");
/* Allowed languages */
$languages = array("ENU");

into your __construct() function and use $this->var instead of $var.

In if(in_array($currency, $this->$currencies) there's missing a closing ).

Same for if(in_array($language, $this->$languages)

You are also accessing the member vars in an incorrect way. You need to use $this->var instead of $this->$var which would access the member variable whose name is stored in $var.
