PHP+MySQL连续插入数据报错：Commands out of sync; you can't run this command now & 读取Excel数据并批量插入到数据中

问题1：

需要从Excel中读取数据，插入到数据库中，而且是三个表，插入第一表成功，插入第二个表时报错：Commands out of sync; you can't run this command now。（一般在框架中不会出现该问题）

原因是：

当执行完query后，MySQL会保存有返回地查询结果集。我执行下次插入数据的时候未释放结果集导致

解决方式：

        do
        {
            if ($result = $db->store_result()){//从准备好的sql语句传递结果集
                $result->close(); //釋放結果我的人們
            }
        } while ($db->next_result());//取出下一个结果

2：从excel读取数据并批量插入到MySQL数据库中。上代码：

canRead($filePath)){
    $PHPReader = new PHPExcel_Reader_Excel5();
    if(!$PHPReader->canRead($filePath)){
        echo 'no Excel';
        return ;
    }
}

$user_info = array();
$key_arr = array(
	'imei','meid','imei2','terminal_model','color','city','district','organize','organ_code','username','user_code','user_iphone'
);

$PHPExcel = $PHPReader->load($filePath);
/**读取excel文件中的第一个工作表*/
$currentSheet = $PHPExcel->getSheet(0);
/**取得最大的列号*/
$allColumn = $currentSheet->getHighestColumn();
/**取得一共有多少行*/
$allRow = $currentSheet->getHighestRow();
/**从第二行开始输出，因为excel表中第一行为列名*/
for($currentRow = 2;$currentRow <= $allRow;$currentRow++){
	/**从第A列开始输出*/
	$single_info = array();
	$i = 0;
	for($currentColumn= 'A';$currentColumn<= $allColumn; $currentColumn++){
		$val = $currentSheet->getCellByColumnAndRow(ord($currentColumn) - 65,$currentRow)->getValue();/**ord()将字符转为十进制数*/
		$single_info[$key_arr[$i]] = $val;
		$i++ ;
	}
	$user_info[] = $single_info;
}
