参数

$data

The data to be repaired.

$config

The config$configcan be passed either as an array or as a string. If a string is passed, it is interpreted as the name of the configuration file, otherwise, it is interpreted as the options themselves.

Check » http://tidy.sourceforge.net/docs/quickref.html for an explanation about each option.

$encoding

The$encodingparameter sets the encoding for input/output documents. The possible values for encoding are:ascii,latin0,latin1,raw,utf8,iso2022,mac,win1252,ibm858,utf16,utf16le,utf16be,big5, andshiftjis.

范例

tidy::repairString() example

<?php
ob_start();
?>
<html>
  <head>
    <title>test</title>
  </head>
  <body>
    <p>error</i>
  </body>
</html>
<?php
$buffer = ob_get_clean();
$tidy = new tidy();
$clean = $tidy->repairString($buffer);
echo $clean;
?>

以上例程会输出：

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<head>
<title>test</title>
</head>
<body>
<p>error</p>
</body>
</html>

You can also use this function to repair xml, for example if stray ampersands etc are breaking it:
<?php
$xml = tidy_repair_string($xml, array(
  'output-xml' => true,
  'input-xml' => true
));
?>

Using tidy is very simple to fix a broken ods/odt document
I wrote the following code to be run from command line
<?php
$zip = new ZipArchive();
if ($zip->open($argv[1])) {
 $fp = $zip->getStream('content.xml'); //file inside archive
 if(!$fp)
  die("Error: can't get stream to document file");
 $stat = $zip->statName('content.xml');
 $buf = ""; //file buffer
 ob_start(); //to capture CRC error message
  while (!feof($fp)) {
   $buf .= fread($fp, 2048); 
  }
  $s = ob_get_contents();
 ob_end_clean();
 fclose($fp);
 $zip->close();
 $config = array(
   'indent' => true,
   'clean' => true,
   'input-xml' => true,
   'output-xml' => true,
   'wrap'    => false
 );
 $tidy = new Tidy();
 $xml = $tidy->repairstring($buf, $config);
 $array=split("\n",$xml);
 $file=tempnam("/tmp","xml");
 $fp=fopen($file,"rw+");
 foreach ($array as $key=>$value) {
  fwrite($fp,trim($value),strlen(trim($value)));
  if ($key==0) {
   fwrite($fp,"\n");
  }
 }
 fclose($fp);
 if ($zip->open($argv[1]) === TRUE) {
  $zip->deleteName('content.xml');
  $zip->addFile($file, 'content.xml');
  $zip->close();
  echo 'recovery complete';
 } else {
  echo 'recovery failed';
 }
 unlink($file);
}
?>
save it to a file called fixdoc and invoke as:
php fixdoc yourbrokendoc
for your safety, please work on a copy of your doc.

The docs referenced at http://tidy.sourceforge.net/docs/quickref.html above state that the configuration option 'sort-attributes' is an enumeration of 'none' and 'alpha', thereby specifying that strings of either form are the acceptable values. This may not be the case, however - on my system, the option was not honored until I set it to true. This may also be the case with other options, so experiment a bit. The output of tidy::getConfig() may be useful in this regard.
