Error de sintáxis

[Ensy]

Hola, alguien me puede decir el error de sintáxis que hay en este código?? Muchas gracias!!!

Código:

function ReadMetaTags($html) 
{ 
//! @return void 
//! @desc Pass meta tag info to PDF file properties 
$regexp = '/ (\\w+?)=([^\\s>"]+)/si'; // changes anykey=anyvalue to anykey="anyvalue" (only do this when this happens inside tags) 
  $html = preg_replace($regexp," \$1=\"\$2\"",$html); 
  $regexp = '/<meta .*?(name|content)="(.*?)" .*?(name|content)="(.*?)".*?>/si'; 
  preg_match_all($regexp,$html,$aux); 
  
  $firstattr = $aux[1]; 
  $secondattr = $aux[3]; 
  for( $i = 0 ; $i < count($aux[0]) ; $i++) 
  { 

     $name = ( strtoupper($firstattr[$i]) == "NAME" )? strtoupper($aux[2][$i]) : strtoupper($aux[4][$i]); 
     $content = ( strtoupper($firstattr[$i]) == "CONTENT" )? $aux[2][$i] : $aux[4][$i]; 
     switch($name) 
     { 
       case "KEYWORDS": $this->SetKeywords($content); break; 
       case "AUTHOR": $this->SetAuthor($content); break; 
       case "DESCRIPTION": $this->SetSubject($content); break; 
     } 
  } 
  //Comercial do Aplicativo usado (no caso um script): 
  $this->SetCreator("HTML2FPDF >> http://html2fpdf.sf.net"); 
}

Saludos!!
