PHP Manual: Return warnings and errors which occurred parsing the specified document

Object-oriented style (property):

public stringnull$tidy->errorBuffer;

Procedural style:

stringfalse tidy_get_error_buffer(tidy $tidy)

Returns warnings and errors which occurred parsing the specified document.

Returns the error buffer as a string, or false if the buffer is empty.

Example #1 tidy_get_error_buffer example

<?php
$html = '<p>paragraph</p>';

$tidy = tidy_parse_string($html);

echo tidy_get_error_buffer($tidy);
/* or in OO: */
echo $tidy->errorBuffer;
?>

The above example will output:

line 1 column 1 - Warning: missing <!DOCTYPE> declaration
line 1 column 1 - Warning: inserting missing 'title' element

tidy::$errorBuffer
