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();
}

?>

以上例程会输出：

bool(false)

When using this funtion, be sure to clear your internal error buffer. If you dn't and you are using this in a long running process, you may find that all your memory is used up.

When using libxml_use_internal_errors(true), and perform a possibly memory intensive operation like simplexml_load_string() next, you might end up with a blank screen and no php error logged because the error message been suppressed.

We use a custom error handler using  set_error_handler()  I found that after I call

libxml_use_internal_errors(false); 

It resets my error_handler - not sure if this is a bug or not, I will report it as a bug - however, I needed to repeat my call to set_error_handler 

(did confuse me for a while)
