Question

I have a static class like this.

<?php

class Language
{
    public static $language = array();
    var $config;

    function __construct($config)
    {
        switch(strtoupper($config['LANGUAGE']))
        {
            case 'ENGLISH':
                self::setEnglish();
                break;

            case 'TURKISH':
                self::setTurkish();
                break;

            default:
                self::setEnglish();
        }
    }

    public static function setEnglish()
    {
        self::$language = array(

                'CHAIN_VALIDATOR_INITIALIZED' => 'ChainValidator initialized!',
                'ERROR_FUNCTION_RETURNED_FALSE' => 'A function returned false.',
            );
    }

    public static function setTurkish()
    {
        self::$language = array(

                'CHAIN_VALIDATOR_INITIALIZED' => 'ChainValidator çalışıyor!',
                'ERROR_FUNCTION_RETURNED_FALSE' => 'Bir fonksiyon false döndürdü.',
            );
    }

    public static function getLanguage($key)
    {
        return isset(self::$language[$key]) ? self::$language[$key] : $key;
    }
}

?>

It is being used like this,

Language::getLanguage('CHAIN_VALIDATOR_INITIALIZED')

but I have to pass more parameters. Similar to this,

Language::getLanguage('CHAIN_VALIDATOR_INITIALIZED', array(__FUNCTION__))

These parameters should be passed in an order, like %s. Final look should look like this:

 "A function returned false" to;
 "%s function returned false"

 And output would be;
 "myLovelyFunction() returned false" (the first array parameter, which is __FUNCTION__)

Sounds like piece of cake my brain stopped atm.

How can I do this?

Answer 1

You can use call_user_func_array and sprintf for that, e.g.

<?php
foo();

function foo() {
    $text = format('CHAIN_VALIDATOR_INITIALIZED', array(__FUNCTION__, __LINE__));
    echo $text;
}

function format($key, $params) {
    $format = '%s@%s: function returned false'; // =getLanguage($key)
    array_unshift($params, $format);
    return call_user_func_array('sprintf', $params);
}

prints

foo@5: function returned false
