PHP libxml_get_errors() Function
Definition and Usage
The libxml_get_errors() function is used to retrieve all errors generated during the process of loading or parsing XML documents. This function must be used in conjunction with libxml_use_internal_errors(). When libxml_use_internal_errors(TRUE) is set, libxml will suppress default error handling, allowing you to manually retrieve error information via libxml_get_errors().
Syntax
libxml_get_errors()Parameters
This function has no parameters.
Return Value
Returns an array containing LibXMLError objects. If no errors are found, it returns an empty array.
Example
Example 1
Use libxml_get_errors() to get error information when loading an XML file fails:
<?php
libxml_use_internal_errors(true);
$xml = simplexml_load_file("test.xml");
if ($xml === false) {
$errors = libxml_get_errors();
foreach ($errors as $error) {
echo "Error: " . $error->code . "<br>";
echo "Message: " . $error->message . "<br>";
echo "Line: " . $error->line . "<br>";
echo "Column: " . $error->column . "<br>";
}
libxml_clear_errors();
}
?>Example 2
Display all error details using print_r():
<?php
libxml_use_internal_errors(true);
$xml = simplexml_load_file("test.xml");
if ($xml === false) {
$errors = libxml_get_errors();
print_r($errors);
libxml_clear_errors();
}
?>Possible output:
Array
(
=> LibXMLError Object

=> 1
