Read JSON values from URL via PHP

问题

i have url with this simple JSON {"result":true,"data":[{"Position":"135"}]}

I tried to read it with this:

$json = file_get_contents('https://...link/here..');
$obj = json_decode($json);
echo $obj->result[1]->data->Position;

but it not works. Where i do a mistake? Thanks for helping!

回答1:

You are incorrectly addressing the data in the PHP object created from the JSON String

$json = file_get_contents('https://...link/here..');
$obj = json_decode($json);
echo $obj->data[0]->Position;

Or if there are more occurances

foreach ( $obj->data as $idx=>$data) {
    echo $data->Position;
}
