我的欲望故事会是这样的：
BRAC Delivery Centre 371/A Shahinbag 23.77311734 90.396355125
EPI Centre (Govt.) Mohakhali Road 23.77746206 90.399232078125
从 lat long 数组我总是尝试收集第一个 lat long。
谁能给我解决办法？
【问题讨论】：
*** 不是免费的编码服务。在发布问题之前进行研究并尝试。您的问题没有资格获得答案，因为它太宽泛了。 如果你想 从 lat long 数组中我总是尝试收集第一个 lat long，那么90.399232078125 是错误的，因为它是下一行的 long Society for听力障碍儿童援助 (SAHIC)
请提供您尝试过的内容..
$assoc = true; $result = json_decode ($json, $assoc); foreach($result as $single_res) $lat = $single_res[0][0]; $long = $single_res[0][1]; $key = $single_res[2]; $name = $key[2]; print_r($key); print_r($name);我无法从第二个索引接收价值。因为运行时我不知道数组索引值。比如 1371618448317 是索引值

解决方案
-
坐标在第一个数组中。
姓名和地址在第三位。
$row[0][0].','.$row[0][1]; 在下面的给定循环中轻松选择坐标。
对于地址和名称，您需要选择第三个数组的键，在这里我使用了$row[2][key($row[2]);
现在检查下面的代码。
$new_array = array();
$i=0;
foreach($array as $key => $row)
//echo "<pre>";print_r(key($row[2]));
$new[$i]['coordinates'] = $row[0][0].','.$row[0][1];
$new[$i]['name'] = $row[2][key($row[2])][1];
$new[$i]['address'] = $row[2][key($row[2])][2];
$i++;
echo "<pre>";print_r($new);
输出
Array
(
[0] => Array
(
[coordinates] => 23.77311734,90.396355125
[name] => BRAC Delivery Centre
[address] => 371/A Shahinbag
)
[1] => Array
(
[coordinates] => 23.77894566,90.39968559375
[name] => EPI Centre (Govt.)
[address] => Mohakhali Road Mohakhali
)
[2] => Array
(
[coordinates] => 23.77746206,90.399232078125
[name] => Society for Assistance to Hearing Impaired Children (SAHIC)
[address] => N/A Sattola Road Mohakhali
)
[3] => Array
(
[coordinates] => 23.77357261,90.36189965625
[name] => Natoinal Health Care Network
[address] => 3/Ka Pisiculture Housing Society Shamoly
)
)

【参考方案2】：自己解决了：
$assoc = true;
$result = json_decode ($json, $assoc);
echo "<table border='1'>";
echo "<tr><td>Hospital Name</td><td>Address</td><td>Lat1</td><td>Long1</td><td>Lat2</td><td>Long1</td><td>Lat3</td><td>Long3</td><td>Lat4</td><td>Long4</td></tr>";
foreach($result as $single_res)
$lat1 = $single_res[0][0];
$long1 = $single_res[0][1];
$lat2 = $single_res[0][2];
$long2 = $single_res[0][3];
$lat3 = $single_res[0][4];
$long3 = $single_res[0][5];
$lat4 = $single_res[0][6];
$long4 = $single_res[0][7];
$key = $single_res[2];
$key_val = array_keys($key);
$key_val = $key_val[0];
$name = $key[$key_val][1];
$address = $key[$key_val][2];
