我做了一个发出API请求的函数。（functions.php） 我已经将这个函数调用到一个名为 （results.php） 的文件中，该函数从搜索输入中选择 ID 从数据库中获取纬度和长度，我希望能够对返回的数据对每个执行操作。对于每个对象，将纬度和经度存储到数组中。将 json 数据粘贴到 json 查看器中，以便更好地查看它。整个事情从数据库连接到数据输出，我只是不知道如何将这些json数据存储到变量中，就像我说的那样，将每个对象的纬度和长度放入数组中
功能。.PHP
function locate($id, $connect) { //connect is coming from connection.php
// Using prepared Statements means that SQL injection is not possible. Selects ID from search input takes lat and long.
if ($stmt = $connect->prepare("SELECT Lat, Lng FROM List WHERE ID = ? LIMIT 1")or die(mysql_error())) {
$stmt->bind_param('i', $id ); // Bind "$id" to parameter.
$stmt->execute(); // Execute the prepared query.
$stmt->store_result();
$stmt->bind_result($lat, $lng); // get variables from result.
$stmt->fetch();
if($stmt->num_rows == 1) // If the id exists
{
// Point to where you downloaded the phar
include('httpful.phar');
// Api request!
$response = 'Httpful'Request::get('https://data.police.uk/api/crimes-street/all-crime?lat='.$lat.'&lng='.$lng)->send();
echo $response;
}
else
{
// No lat & long exists.
echo 'noUser';
return false;
}
}}
结果。.PHP
$id=$_POST["hiddenField"]; //ID equals the hidden field post made from the search university form
locate($id, $connect); //function from functions.PHP

请参阅json_decode()：
//Input (json) string/array
$string = '[{"Foo":"bar","123":456}]';
//Convert to PHP array
$array = json_decode($string, true):
//Output to check
print_r($array);
以上将输出：
Array
(
[0] => Array
(
[Foo] => bar
[123] => 456
)
)
