    If you use strict_types=1, you'll get the warning "Notice: Resource ID#... used as offset, casting to integer".

    Use

    <?php $depth[(int) $parser]  ?>

    instead of

    <?php $depth[$parser]  ?>

    The following example will echo back an xml file using the basic event based parser.  Currently, (at least in the version of PHP5 I'm using) it will skip The XML declaration and the Doctype declaration--they don't seem to be captured by the default handler.

    <?php
    echo "<pre>";

    $file = "test.xml";
    echo     $file."\n";
    global     $inTag;

    $inTag = "";
    $xml_parser = xml_parser_create();
    xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, 0);
    xml_parser_set_option($xml_parser, XML_OPTION_SKIP_WHITE, 1);
    xml_set_processing_instruction_handler($xml_parser, "pi_handler");
    xml_set_default_handler($xml_parser, "parseDEFAULT");
    xml_set_element_handler($xml_parser, "startElement", "endElement");
    xml_set_character_data_handler($xml_parser, "contents");

    if (!(    $fp = fopen($file, "r"))) {
        if (!    xml_parse($xml_parser, $data, feof($fp))) {
           die(     sprintf("XML error: %s at line %d",
                                    xml_error_string(xml_get_error_code($xml_parser)),
                                    xml_get_current_line_number($xml_parser)));
        }
    }
    while (    $data = fread($fp, 4096)) {
