php - Warning: PDOStatement::execute(): message: Unclosed quotation mark after the character string -

how sanitize data won't cause errors? i'm running ubuntu, php 5.3 , connecting mssql.

this code:

            $body = $this->get_part($imap, $b, "text/html");             if($body == "")             {                 $body = $this->get_part($imap, $b, "text/plain");             }             $header = imap_headerinfo($imap, $b);             $subject = $header->subject;             $fromaddress = $header->fromaddress;             $body = str_replace("'", "''", $body);             //$body = str_replace("\"", "\"\"", $body);             /////////////////////////////             $data = array('content'=>$body);             $query = $pdo->prepare('insert [tbl_test] (content) values (:content)');             $query->execute($data);             break;
