libxml_get_errors
LIBXML_GET_ERRORS(3) 1 LIBXML_GET_ERRORS(3)libxml_get_errors - Retrieve array of errorsSYNOPSIS
array libxml_get_errors (void )
DESCRIPTION
Retrieve array of errors.
RETURN VALUES
Returns an array with LibXMLError objects if there are any errors in the buffer, or an empty array otherwise.
EXAMPLES
Example #1
A libxml_get_errors(3) example
This example demonstrates how to build a simple libxml error handler.
<?php
libxml_use_internal_errors(true);
$xmlstr = <<< XML
<?xml version='1.0' standalone='yes'?>
<movies>
<movie>
<titles>PHP: Behind the Parser</title>
</movie>
</movies>
XML;
$doc = simplexml_load_string($xmlstr);
$xml = explode("
", $xmlstr);
if (!$doc) {
$errors = libxml_get_errors();
foreach ($errors as $error) {
echo display_xml_error($error, $xml);
}
libxml_clear_errors();
}
function display_xml_error($error, $xml)
{
$return = $xml[$error->line - 1] . "
";
$return .= str_repeat('-', $error->column) . "^
";
switch ($error->level) {
case LIBXML_ERR_WARNING:
$return .= "Warning $error->code: ";
break;
case LIBXML_ERR_ERROR:
$return .= "Error $error->code: ";
break;
case LIBXML_ERR_FATAL:
$return .= "Fatal Error $error->code: ";
break;
}
$return .= trim($error->message) .
"
Line: $error->line" .
"
Column: $error->column";
if ($error->file) {
$return .= "
File: $error->file";
}
return "$return
--------------------------------------------
";
}
?>
The above example will output:
<titles>PHP: Behind the Parser</title>
----------------------------------------------^
Fatal Error 76: Opening and ending tag mismatch: titles line 4 and title
Line: 4
Column: 46
--------------------------------------------
