<?php
    public function __construct()
    {
        // Static varibles - no need to recalc every time we new getid3.
        static $include_path;
        static $iconv_present;

        static $initialized;
        if ($initialized) {
            // Import static variables
            $this->include_path  = $include_path;
            $this->iconv_present = $iconv_present;

            // Run init checks only on first instance.
            return;
        }

        // Get include_path
        $this->include_path = $include_path = dirname(__FILE__) . '/';

        // Check for presence of iconv() and make sure it works (simpel test only).
        if (function_exists('iconv') && @iconv('UTF-16LE', 'ISO-8859-1', @iconv('ISO-8859-1', 'UTF-16LE', getid3::ICONV_TEST_STRING)) == getid3::ICONV_TEST_STRING) {

It seems like @iconv('ISO-8859-1', 'UTF-16LE', getid3::ICONV_TEST_STRING) can also be of type false; however, parameter $string of iconv() does only seem to accept string, maybe add an additional type check?

        } // iconv() not present - load replacement module.
