note 74211 added to ref.pdf

I am trying to extract the text from PDF files and use it to feed a search engine (Intranet tool). I tried several functions "PDF2TXT" posted below, but not they do not produce the expected result. At least, all words need to be separated by spaces (then used as keywords), and the "junk" codes removed (for example: binary data, pictures...). I start modifying the interesting function posted by Swen, and here is the my current version that starts to work quite well (with PDF version 1.2). Sorry for having a quite different style of programming. Luc <?php // Patch for pdf2txt() posted Sven Schuberth // Add/replace following code (cannot post full program, size limitation) // handles the verson 1.2 // New version of handleV2($data), only one line changed function handleV2($data){ // grab objects and then grab their contents (chunks) $a_obj = getDataArray($data,"obj","endobj"); foreach($a_obj as $obj){ $a_filter = getDataArray($obj,"<<",">>"); if (is_array($a_filter)){ $j++; $a_chunks[$j]["filter"] = $a_filter[0]; $a_data = getDataArray($obj,"stream\r\n","endstream"); if (is_array($a_data)){ $a_chunks[$j]["data"] = substr($a_data[0], strlen("stream\r\n"), strlen($a_data[0])-strlen("stream\r\n")-strlen("endstream")); } } } // decode the chunks foreach($a_chunks as $chunk){ // look at each chunk and decide how to decode it - by looking at the contents of the filter $a_filter = split("/",$chunk["filter"]); if ($chunk["data"]!=""){ // look at the filter to find out which encoding has been used if (substr($chunk["filter"],"FlateDecode")!==false){ $data =@ gzuncompress($chunk["data"]); if (trim($data)!=""){ // CHANGED HERE, before: $result_data .= ps2txt($data); $result_data .= PS2Text_New($data); } else { //$result_data .= "x"; } } } } return $result_data; } // New function - Extract text from PS codes function ExtractPSTextElement($SourceString) { $CurStartPos = 0; while (($CurStartText = strpos($SourceString, '(', $CurStartPos)) !== FALSE) { // New text element found if ($CurStartText - $CurStartPos > 8) $Spacing = ' '; else { $SpacingSize = substr($SourceString, $CurStartPos, $CurStartText - $CurStartPos); if ($SpacingSize < -25) $Spacing = ' '; else $Spacing = ''; } $CurStartText++; $StartSearchEnd = $CurStartText; while (($CurStartPos = strpos($SourceString, ')', $StartSearchEnd)) !== FALSE) { if (substr($SourceString, $CurStartPos - 1, 1) != '\\') break; $StartSearchEnd = $CurStartPos + 1; } if ($CurStartPos === FALSE) break; // something wrong happened // Remove ending '-' if (substr($Result, -1, 1) == '-') { $Spacing = ''; $Result = substr($Result, 0, -1); } // Add to result $Result .= $Spacing . substr($SourceString, $CurStartText, $CurStartPos - $CurStartText); $CurStartPos++; } // Add line breaks (otherwise, result is one big line...) return $Result .
