Question

I can’t figure out why this error in php 5.4.

Strict Standards: Non-static method dbInstance::getInstance() should not be called statically

The class is:

class dbInstance
{
    private static $db;

    public static function getInstance()
    {
        if (! self::$db) self::$db = new db();
        return self::$db;
    }
}

I call it like:

 $registry->db = $db = dbInstance::getInstance()

Thanks

I can’t reproduce the error. Are you absolutely sure you’ve edited the right file? Or maybe you are seeing a cached version of the output?

<?php
$db = dbInstance::getInstance();

class dbInstance
{
    private static $db;

    public static function getInstance()
    {
        if (! self::$db) self::$db = new db();
        return self::$db;
    }
}

class db {
    public function __construct() {
        echo 'db::construct filemtime=', date('Y-m-d H:i:s', filemtime(__FILE__)), ' PHPVERSION=', PHP_VERSION;
    }
}

prints on my computer

db::construct filemtime=2012-07-27 14:50:37 PHPVERSION=5.4.1
