Failed to prepared the statement!

[xbatista]

So I have a problem with prepare statement, at all everything works, but it won't work if I bind $table, any suggestions?

execSQL("SELECT id FROM ? WHERE id=?", array('si', $table, $u_id), style::Q_NUM_ROWS)

const Q_GET_VALUE = 0;
const Q_NUM_ROWS = 1;
const Q_AFFECTED_ROWS = 2;

function user_exists($u_id, $table)
{
	if ( $this->execSQL("SELECT id FROM ? WHERE id=?", array('si', $table, $u_id), style::Q_NUM_ROWS) != 0 )
		return true;
		
	return false;
}
	function execSQL($sql, $params, $exec_type)
	{
		$stmt = $this->db_connect->prepare($sql) or die ("Failed to prepared the statement!");
        
		if ( !empty($params) )
			call_user_func_array(array($stmt, 'bind_param'), $this->refValues($params));
    
		$stmt->execute();
            
		if ( $exec_type == self::Q_GET_VALUE ) 
		{
			$parameters = array();
		
			$meta = $stmt->result_metadata();
             
			while ( $field = $meta->fetch_field() ) {
				$parameters[] = &$row[$field->name];
			}  
         
			call_user_func_array(array($stmt, 'bind_result'), $this->refValues($parameters));
                
			$stmt->fetch();
		
			$result = $row;
		}
		else if( $exec_type == self::Q_NUM_ROWS)
		{
			$stmt->store_result();
			$result = $stmt->num_rows;
		} 
		else
		{
			$result = $stmt->affected_rows;
		}
            
		$stmt->close();

		return $result;
	}
function refValues($arr)
	{
		if (strnatcmp(phpversion(),'5.3') >= 0) //Reference is required for PHP 5.3+
		{
			$refs = array();
			foreach($arr as $key => $value)
				$refs[$key] = &$arr[$key];
				
			return $refs;
		}
		
		return $arr;
	}
