Добрый день, собственно есть огромное количество регулярных выражений в файле и в двух местах используется eval. После перевода хостинга на php 5.3 стала появляться ошибка при использовании одного из них.
Parse error: syntax error, unexpected '{' in /home/sarushen/public_html/lib/class_datafile.php(436) : eval()'d code on line 1

Сама функция:

function formatRecord($index)
      {
          $result = "";
          if (($index >= 0) && ($index < $this->row_count))
          {
              $i = $index;
			eval($this->format_expression);
              return $row_str;
          }
          else
              return "";
      }

Если распечатать то, что передается в eval

echo $this->format_expression; 

То увидим на странице будет выведено:

$row_str = ($this->headers[0][$i] == 3) ? (preg_replace(array("/\{\#\}/", "/\{\&\}/", "/\{\*\}/", "/\{id\}/", "/\{\^id\}/", "/\{question\}/", "/\{\^question\}/"), array($i, $this->current, $this->row_count, $this->headers[0][$i], strtoupper($this->headers[0][$i]), $this->headers[4][$i], strtoupper($this->headers[4][$i])), "")) : ("");$row_str = ($this->headers[0][$i] == 3) ?

Есть идеи какие-нить?)
