              <?php$jsonfile = json_decode($getfile);  ?>

           <?php foreach ($jsonfile->features as $index => $obj): ?>
            <?php echo $obj->Name; ?>
            <?php echo $obj->Northing; ?>
           <?php echo $obj->Eastinglink; ?>

Answer 1

所有必需的属性都在属性键下。更改您的代码以阅读下文。

echo $obj->properties->NAME ;
echo $obj->properties->Northing; 
echo $obj->properties->Eastinglink;
