I am trying to parse a xml file using the expat parser functions. The code works fine when I run on small xml files(20 K), but it doesn't work for the larger xml files (20 M😎. This is my code for reading the file:
function readAllInfo()
{
global $file, $topics;
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
xml_set_external_entity_ref_handler($xml_parser, "externalEntityHandler");
xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, false);
if (!($fp = fopen($file, "r"))) {
die("could not open XML input");
}
while ($data = fread($fp, 4096)) {
if (!xml_parse($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)));
}
}
xml_parser_free($xml_parser);
return $topics;
}
Can anyone please help me?
