我目前正在运行一个 MySQL 脚本while loop
,如下所示:
$Query = mysql_query("SELECT * FROM appointments");
while ($Rows = mysql_fetch_array($Query))
{
...
}
这会将单行作为数组返回,我可以根据需要对其进行操作,例如:
if ($Rows['Reoccour'] == 1)
{
$NextDate = date('o-m-d', strtotime($Rows['Date'] . " +" . $Rows['howfar'] . " weeks"));
if ($NextDate < date('o-m-d'))
{
mysql_query("UPDATE appointments SET Date='$NextDate' WHERE ID='{$Rows['ID']}'");
}
}
这将放置在 while 循环中,以便我可以使用数组本身。但我想迁移到 PDO,但我无法获得array
我想要的格式:
这是我的代码:
$Query = $dbh->prepare("SELECT * FROM appointments");
$Query->execute();
$Results = $Query->fetchAll();
print_r($Results);
这将产生一个多维数组,如下所示:
Array (
[0] => Array (
[ID] => 1
[0] => 1
[Appointment] => JCP Lucy
[1] => JCP Lucy
[Date] => 2012-12-21
[2] => 2012-12-21
[Location] => Grays JCP
[3] => Grays JCP
[Reoccour] => 1
[4] => 1
[howfar] => 1
[5] => 1
)
[1] => Array (
[ID] => 3
[0] => 3
[Appointment] => JCP Sign On
[1] => JCP Sign On
[Date] => 2012-12-14
[2] => 2012-12-14
[Location] =>
JCP Grays
[3] => JCP Grays
[Reoccour] => 1
[4] => 1
[howfar] => 2
[5] => 2 )
)
我想要做的是在我使用 MySQL 函数时使用$Results = $Query->fetchAll();
的设置中。while loop
如果我想将数组缩小到单个字符串,我将不得不执行以下操作:
foreach ($Results AS $results)
{
foreach ($results AS $result)
{
echo "{$result} <br>";
}
}
但这会返回:
1
JCP Lucy
JCP Lucy
2012-12-21
2012-12-21
Grays JCP
Grays JCP
1
1
1
1
3
3
JCP Sign On
JCP Sign On
2012-12-14
2012-12-14
JCP Grays
JCP Grays
1
1
2
2
其中有重复的值。我的问题是:
1)删除重复的值
2) 使用我的 PDO Api 执行一段while loop
时间——但让我能够像我在完成这些mysql_fetch_array
功能时一样使用 Array 键。
