所以我有一些数据从数据库查询返回,结果数组(得到print_r)看起来像这样(它被分配给一个名为$ locationData的var):
Array
(
[0] => Array
(
[id] => 1
[location_name] => Cook Minnesota
[location_lat] => 47.72037
[location_long] => -90.32667
)
[1] => Array
(
[id] => 2
[location_name] => Lake Minnesota
[location_lat] => 47.18238
[location_long] => -91.35301
)
[2] => Array
(
[id] => 3
[location_name] => St. Louis Minnesota
[location_lat] => 46.83572
[location_long] => -91.96299
)
)
我有一个foreach循环,需要从每个循环中获取location_name。它看起来像这样:
foreach ($locationData as $location => $value ) {
echo '<p>name ' . $location['location_name']. '</p>';
}
我99%肯定这应该有效;它基本上和我以前用过十几次的代码相同。但回声并没有返回任何东西 - 甚至不是静态文本(<p>name
)。它没有抛出任何错误,如果我尝试执行print_r($ location),我什么也得不到。
有什么想法吗?我确信这很简单。

您希望$value['location_name']
因为$value
代表数组,而$location
代表数组的索引:
echo '<p>name ' . $value['location_name']. '</p>';
答案 1 :(得分:0)
是:
foreach ($locationData as $location => $value ) {
echo '<p>name ' . $value['location_name']. '</p>';
}
