Is there an alternative of str_ireplace if somebody has a php vesion <5?
I seached php.net but didn't find anything

preg_replace is case insensitive, if you set the correct parameters:

PHP Code:

function ($find, $replace, $string)
{
    if (is_array($find))
    {
        $regfind = array();
        // sanitize findarray
        foreach ($find AS $findstring)
        {
            $regfind[] = '#' . preg_quote($findstring, '#') . '#i';
        }
    }
    else
    {
        $regfind = '#' . preg_quote($find, '#') . '#i';
    }
    return preg_replace($regfind, $replace, $string);
} 


(that should work normally, but not tested
