示例 #1 A libxml_use_internal_errors() example

This example demonstrates the basic usage of libxml errors and the value returned by this function.

<?php

// enable user error handling
var_dump(libxml_use_internal_errors(true));

// load the document
$doc = new DOMDocument;

if (!$doc->load('file.xml')) {
foreach (libxml_get_errors() as $error) {
// handle errors here
}

libxml_clear_errors();
