It will ignore anything that is not addressed as text within the PDF and any layout. Currently supported filters are: ASCIIHexDecode, ASCII85Decode, FlateDecode PURPOSE(S): Most likely for people that want their PDF to be searchable. SYNTAX: include('class.pdf2text.php'); $a = new PDF2Text(); $a->setFilename('test.pdf'); $a->decodePDF(); echo $a->output(); ALTERNATIVES: Other excellent options to search within a PDF: - Apache PDFbox (https://pdfbox.apache.org/). An open source Java solution - pdflib TET (https://www.pdflib.com/products/tet/) - Online converter: https://snowtide.com/PDFTextStream */ class PDF2Text { // Some settings var $multibyte = 2; // Use setUnicode(TRUE|FALSE) var $convertquotes = ENT_QUOTES; // ENT_COMPAT (double-quotes), ENT_QUOTES (Both), ENT_NOQUOTES (None) // Variables var $filename = ''; var $decodedtext = ''; function setFilename($filename) { // Reset $this->decodedtext = ''; $this->filename = $filename; } function output($echo = false) { if($echo) echo $this->decodedtext; else return $this->decodedtext; } function setUnicode($input) { // 4 for unicode.
