I am using the following code to read MS word .doc files to plain text. I got this code from a stackoverflow post, but I couldnt understand the code completely. But when read some doc like the resume of Adrian (www.iknowkungfoo.com/resume/adrian_j_moreno_resume.doc) the code is returning an fread error. It looks like the header cannot be accessed in this file. Can somebody please explain what is this problem ?
function readWord($filename) {
if(file_exists($filename))
{
if(($fh = fopen($filename, 'r')) !== false )
{
$headers = fread($fh, 0xA00);
//$headers = fread($fh, filesize($filename));
// 1 = (ord(n)*1) ; Document has from 0 to 255 characters
$n1 = ( ord($headers[0x21C]) - 1 );
// 1 = ((ord(n)-8)*256) ; Document has from 256 to 63743 characters
$n2 = ( ( ord($headers[0x21D]) - 8 ) * 256 );
// 1 = ((ord(n)*256)*256) ; Document has from 63744 to 16775423 characters
$n3 = ( ( ord($headers[0x21E]) * 256 ) * 256 );
// 1 = (((ord(n)*256)*256)*256) ; Document has from 16775424 to 4294965504 characters
$n4 = ( ( ( ord($headers[0x21F]) * 256 ) * 256 ) * 256 );
// Total length of text in the document
$textLength = ($n1 + $n2 + $n3 + $n4);
//var_dump($headers);
$extracted_plaintext = fread($fh, $textLength);
// if you want to see your paragraphs in a new line, do this
// return nl2br($extracted_plaintext);
return $extracted_plaintext;

return false;
