Question

在创建统计程序时，我会跟踪每小时有多少架飞机到达机场。

我的脚本计算过去一小时的航班数量并将其保存到数据库中。如果我在phpmyadmin中复制语句，它会继续获取mysql语法错误

$date = 2013091713;
//$date = date('YmdH', mktime(date('H')));

$sql = '';
foreach ($aerodrome as $icao => $value) {
    $sql .= "INSERT INTO flightsperhour(date, aerodrome, inbound, outbound) 
             VALUES('". $date ."', '" . $icao . "' , " . (isset($value['inboud']) ? $value['inboud'] : 0)  . ", " . (isset($value['outbound']) ? $value['outbound'] : 0) . ");";
}
//INSERT INTO flightsperhour(date, aerodrome, inbound,outbound) VALUES('2013091713', 'EBBR' , 0, 1);
//INSERT INTO flightsperhour(date, aerodrome, inbound,outbound) VALUES('2013091713', 'ELLX' , 0, 1);
if(mysql_query($sql))
{

} else{
    die(mysql_error());
}

编辑：Mysql错误：You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO flightsperhour(date, aerodrome, inbound, outbound) VALUES('2013' at line 2

EDIT2：修复了单个缺失的'

EDIT3：根据编程学生的要求，他的解决方案的print_r

INSERT INTO flightsperhour(date, aerodrome, inbound, outbound) 
             VALUES('2013091713', 'EBBR' , '', '1'),
             VALUES('2013091713', 'ELLX' , '', '1')
You have an error in your SQL syntax; check the manual that corresponds to your 
MySQL server version for the right syntax to use 
near 'VALUES('2013091713', 'ELLX' , '', '1')' at line 3

Answer 1

'和$date之间缺少冒号$icao。

更正后的代码：

$date = 2013091713;
//$date = date('YmdH', mktime(date('H')));

$sql = '';
 $sql .= "INSERT INTO flightsperhour(date, aerodrome, inbound, outbound) ";
foreach ($aerodrome as $icao => $value) {
    $inbound = isset($value['inboud']) ? $value['inboud'] : 0;
    $outbound = isset($value['outbound']) ? $value['outbound'] : 0;
    $sql .= "
             VALUES('". $date ."', '" . $icao . "' , '" . $inboud  . "', '" . $outbound . "'),";
}

$sql = substr($sql, 0, strlen($sql)-1);
//INSERT INTO flightsperhour(date, aerodrome, inbound,outbound) VALUES('2013091713', 'EBBR' , 0, 1);
//INSERT INTO flightsperhour(date, aerodrome, inbound,outbound) VALUES('2013091713', 'ELLX' , 0, 1);
if(mysql_query($sql))
{

} else{
    die(mysql_error());
}

Answer 2

您尚未关闭$date将此'". $date ."更改为'". $date ."'

的单引号

$sql .= "INSERT INTO flightsperhour(date, aerodrome, inbound, outbound) 
             VALUES('". $date ."', '" . $icao . "' , " . (isset($value['inboud']) ? $value['inboud'] : 0)  . ", " . (isset($value['outbound']) ? $value['outbound'] : 0) . ");";

Answer 3

建议您使用PDO http://in1.php.net/manual/en/ref.pdo-mysql.php或MySQLi Extension，因为Php 5.5不再支持MySQL扩展

$date = 2013091713;
//$date = date('YmdH', mktime(date('H')));

$db_conn = new PDO('mysql:host=<host>;dbname=<database name>', '<username>', '<password>');


try{
$sql = $db_conn->prepare("INSERT INTO flightsperhour(date, aerodrome, inbound, outbound) VALUES (:date,:aerodrome,:inbound,:outbound)");

foreach ($aerodrome as $icao => $value) {
    $inbound = isset($value['inboud']) ? $value['inboud'] : 0;
    $outbound = isset($value['outbound']) ? $value['outbound'] : 0;
    $sql->execute(
            array(
                ":date" => $date,
                ":aerodrome" => $aerodrome,
                ":inbound" => $inbound,
                ":outbound" => $outbound
            )
    );
}
}
catch (PDOException $pe){
    print $pe->getMessage();
}

多个mysql语句不通过php执行（语句通过phpmyadmin工作）
