早安, 我有这个阵列:
Array (
[0] => Array ( [ID] => 11 [Nome] => Ponte 1)
[1] => Array ( [ID] => 12 [Nome] => Ponte 2 )
[2] => Array ( [ID] => 13 [Nome] => Ponte 3 )
[3] => Array ( [ID] => 14 [Nome] => Ponte 4 )
[4] => Array ( [ID] => 15 [Nome] => Ponte 5 )
[5] => Array ( [ID] => 16 [Nome] => Ponte 6 )
[6] => Array ( [ID] => 17 [Nome] => Ponte 7 )
[7] => Array ( [ID] => 18 [Nome] => Ponte 8 )
[8] => Array ( [ID] => 19 [Nome] => Ponte 9 )
[9] => Array ( [ID] => 20 [Nome] => Ponte 10 )
[10] => Array ( [ID] => 21 [Nome] => Ponte 11 )
[11] => Array ( [ID] => 22 [Nome] => Ponte 12 )
[12] => Array ( [ID] => 23 [Nome] => Ponte 13 )
[13] => Array ( [ID] => 24 [Nome] => Ponte 14 )
[14] => Array ( [ID] => 25 [Nome] => Ponte 15 )
[15] => Array ( [ID] => 26 [Nome] => Ponte 16 )
[16] => Array ( [ID] => 27 [Nome] => Ponte 17 )
[17] => Array ( [ID] => 28 [Nome] => Ponte 18 )
[18] => Array ( [ID] => 29 [Nome] => Ponte 19 )
[19] => Array ( [ID] => 30 [Nome] => Ponte 20 )
[20] => Array ( [ID] => 31 [Nome] => Ponte 21 )
[21] => Array ( [ID] => 32 [Nome] => Ponte 22 )
[22] => Array ( [ID] => 33 [Nome] => Ponte 23 )
[23] => Array ( [ID] => 34 [Nome] => Ponte 24 )
)
我必须只提取数组中的对象:
... etc ...
[ID] => 34 [Nome] => Ponte 24
我怎么能这样做,假设我在这个用MySql创建该数组的类中使用PHP PDO:
$stmt = $this->conn->getConnection()->prepare($query);
foreach($bindParam as $key => &$val){
$stmt->bindParam($key,$val);
}
$stmt->execute();
$row = $stmt->fetchAll(PDO::FETCH_ASSOC);
return ($row);
使用此查询调用:
$query = $query->selectAll("SELECT Name,ID FROM Table WHERE field = :field",array(":field" => 10));
这就是我所做的:
foreach ( $query as $key => $val) {
echo $key."--".$val."<br/>";
}
但似乎没有用,有办法吗? 谢谢你。

试试这个:
foreach ($query as $q) {
foreach ($q as $key => $val) {
echo $key."--".$val."<br/>";
}
}

你需要迭代$val
,因为它也是一个数组..
foreach ( $query as $key => $val) {
echo $key."--".$val."<br/>";
foreach($val as $key1 => $val1){
echo $key1."--".$val1."<br/>";
}
}
HTH!

如果您只想回复每个ID和名称:
foreach ( $query as $val) {
echo $val["ID"];
echo "--";
echo $val["nome"];
echo "<br/>";
}

这是正确的方法:
foreach ( $query as $val) { echo $val['ID']."--".$val['Nome']."<br/>"; }
谢谢Mark。
