[英]JSON Decode Help with PHP
I am having trouble getting some data from a JSON object which I have converted into an array:我无法从已转换为数组的 JSON object 获取一些数据:
This is my Class:这是我的 Class:
class tbfe_json_api {
var $location;
var $latitude;
var $longitude;
var $searchRadius = 20; // Default to 20 Miles
var $reverseGeoCodeJSON;
public function __construct() {
$this->getLocationParams();
$this->getCoords( $this->reverseGeoCodeLocation( $this->location ) );
}
public function getLocationParams() {
if( isset( $_GET['location'] ) ) {
$this->location = str_replace(' ', '' , $_GET['location'] );
if( isset( $_GET['radius'] ) ) {
$this->searchRadius = $_GET['radius'];
}
}
else {
die('Invalid parameters specified for JSON request.');
}
}
public function reverseGeoCodeLocation($location) {
$cURL = curl_init();
curl_setopt($cURL, CURLOPT_URL, 'http://maps.google.com/maps/geo?q='.$location.'&output=json');
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, 1);
return $this->reverseGeoCodeJSON = curl_exec($cURL);
curl_close ($cURL);
}
public function getCoords($json_data) {
$obj = json_decode($json_data, true);
var_dump($obj);
// I NEED THE COORDINATE VALUES HERE TO PLACE BELOW
$this->latitude = '';
$this->longitude = '';
}
}
And this is the array I need to work from: http://www.thebigfishexperience.org.uk/sources/ajax/venue-json.php?location=london这是我需要工作的数组: http://www.thebigfishexperience.org.uk/sources/ajax/venue-json.php?location=london
I need to retrieve the coordinate values from the array and place them into my instance variables as you see above.如上所示,我需要从数组中检索坐标值并将它们放入我的实例变量中。
i believe you need:我相信你需要:
$this->latitude = $obj['Placemark'][0]['Point']['coordinates'][0];
$this->longitude = $obj['Placemark'][0]['Point']['coordinates'][1];
Look at the dump of $obj
and find the two values you're looking for.查看
$obj
的转储并找到您要查找的两个值。 Then reference them to your two variables.然后将它们引用到您的两个变量。
$this->latitude = $obj->path->to->value->one;
$this->longitude = $obj->path->to->value->two;
