Getting raw SQL query string from PDO prepared statements

Question

Is there a way to get the raw SQL string executed when calling PDOStatement::execute() on a prepared statement? For debugging purposes this would be extremely useful.

Answer 1

preg_replace didn't work for me and when binding_ was over 9, binding_1 and binding_10 was replaced with str_replace (leaving the 0 behind), so I made the replacements backwards:

public function interpolateQuery($query, $params) {
$keys = array();
    $length = count($params)-1;
    for ($i = $length; $i >=0; $i--) {
            $query  = str_replace(':binding_'.(string)$i, '\''.$params[$i]['val'].'\'', $query);
           }
        // $query  = str_replace('SQL_CALC_FOUND_ROWS', '', $query, $count);
        return $query;

}

Hope someone finds it useful.
