PHP singleton not accessible

Question

i've got a bit of a problem with getting a singleton to work in php 5.3

What i want to achieve is that i'll be able to include one php file with a class, that lets me translate webpages by a dictionary over a global singleton.

Usage example:

<?php
    include_once "CLocale.php";
?>
//...
<head>
<title><?php CLocale::Instance()->getText("StrMemberArea")?></title>

My class looks like the following at the moment:

class CLocale
{
    private function __clone()
    {
    }

    public static function Instance()
    {
        if (static::$_instance === NULL)
        {
            static::$_instance = new static();
        }
        return static::$_instance;
    }

    private function __construct()
    {
    }

    public function getText($str)
    {
        return "Test";
    }
}

So, the problem is, i don't get any output of "Test" when using the class like shown above, also, i don't get any error. PHP Storm isn't really showing me any errors. Perhaps one of you guys is able to spot a problem somewhere.

Thanks in advance, calav3ra

PS: I don't mind how the singleton is implemented

You're returning it. But you're not passing it to output, as there is no echo call. — ConcurrentHashMap

Sometimes you just need another pair of eyes to look into your code, to see something obvious:) — user133408

I know. Actually, i didn't sleep enough, but still feel ok - but it's always the same :) — calav3ra

Yo forgot to echo the result

<title><?php CLocale::Instance()->getText("StrMemberArea")?></title>

should be:

<title><?php echo CLocale::Instance()->getText("StrMemberArea")?></title>

Ehm - the Singleton code is completely right, but you forgot to output the return value from getText

<?php
    include_once "CLocale.php";
?>
//...
<head>
<title><?php echo CLocale::Instance()->getText("StrMemberArea")?></title>

To get anything displayed you no just need to return it, but also echo or print it. Like this:

<title><?php echo CLocale::Instance()->getText("StrMemberArea")?></title>
