my turn for help please with php tidy

Hey guys I am building a page to validate html using php tidy

I have it working fine but I want to format the repaired output with
indents to make it look good and I cant figure it out. any ideas would be great here is the code I am using

Code:

<?php

$file= $_POST['file'];


$tidy = tidy_parse_string($file);
$tidy->_error_count;


    echo "The following errors were detected:<br>";
    

preg_match_all('/^(?:line (\d+) column (\d+) - )?(\S+): (?:\[((?:\d+\.?){4})]:)
?(.*?)$/m', $tidy->errorBuffer, $tidy_errors, PREG_SET_ORDER);

$malestr = str_replace("line","\nline:",$tidy->errorBuffer);

$article1=nl2br(htmlentities($malestr));
echo "$article1<br>";

$tidy->CleanRepair();
  
echo"<textarea cols=\"80\"rows=\"30\">$tidy</textarea>";
?>

LOL

I did figure it out though.

It cleans up code nice I will post a link when it is looking good. Right now I used a page from my back pain articles section for a template so it looks goofy untill I change the other content.
