[Stanislao]

salve ragazzi...ho trovato questo script che dovrebbe fare una cosa fantastica..ovvero ricercare testi nei pdf con php

di seguito la classe.. e lo script


pdfsearch.php

<?
class pdf_search {
var $_buffer;

function pdf_search($buffer) {
$this->_buffer = $buffer;
}

        // This function returns the next line from the document.
        // If a stream follows, it is deflated into readable text.
        function nextline() {
                $pos = strpos($this->_buffer, "\r");
                if ($pos === false) {
                        return false;
                }
                $line = substr($this->_buffer, 0, $pos);
                $this->_buffer = substr($this->_buffer, $pos + 1);
                if ($line == "stream") {
                        $endpos = strpos($this->_buffer, "endstream");
                        $stream = substr($this->_buffer, 1, $endpos - 1);
                        $stream = @gzuncompress($stream);
                        $this->_buffer = $stream . substr($this->_buffer, $endpos + 9);
                }
                return $line;
        }

        // This function returns the next line in the document that is printable text.
        // We need it so we can search in just that portion.
        function textline() {
                $line = $this->nextline();
                if ($line === false) {
                        return false;
                }
                if (preg_match("/[^\\\\]\\((.+)[^\\\\]\\)/", $line, $match)) {
                      $line = preg_replace("/\\\\(\d+)/e", "chr(0\\1);", $match[1]);
                         
                        return stripslashes($line);
                }
                return $this->textline();
        }

        // This function returns true or false, indicating whether the document contains
        // the text that is passed in $str.
        function textfound($str) {
                while (($line = $this->textline()) !== false) {
                        if (preg_match("/$str/i", $line) != 0) {
                                return true;
                        }
                }
                return false;
        }
}

?>

script index.php

<?
include("pdfsearch.php");
$theDocument = "napoli.pdf";
$searchText = "Iervolino";
$fp = fopen($theDocument, "r");
$content = fread($fp, filesize($theDocument));
fclose($fp);
$pdf = new pdf_search($content);
if ($pdf->textfound($searchText)) {
  echo "ho trovato $searchText.";
}else {
echo "$searchText non è stato trovato.";
}

?>

sapreste dirmi perchè mi da quest' errore?
