Get JSON object from URL
json, php
Solution
$json = file_get_contents('url_here');
$obj = json_decode($json);
echo $obj->access_token;
For this to work, `file_get_contents` requires that `allow_url_fopen` is enabled. This can be done at runtime by including:
ini_set("allow_url_fopen", 1);
You can also use `curl` to get the URL. To use curl, you can use the example found here:
$ch = curl_init();
// IMPORTANT: the below line is a security risk, read https://paragonie.com/blog/2017/10/certainty-automated-cacert-pem-management-for-php-software
// in most cases, you should set it to true
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'url_here');
$result = curl_exec($ch);
curl_close($ch);
$obj = json_decode($result);
echo $obj->access_token;
Problem
I have a URL that returns a JSON object like this: ``` { "expires_in":5180976, "access_token":"AQXzQgKTpTSjs-qiBh30aMgm3_Kb53oIf-VA733BpAogVE5jpz3jujU65WJ1XXSvVm1xr2LslGLLCWTNV5Kd_8J1YUx26axkt1E-vsOdvUAgMFH1VJwtclAXdaxRxk5UtmCWeISB6rx6NtvDt7yohnaarpBJjHWMsWYtpNn6nD87n0syud0" } ``` I want to get JSON object from the URL and then the `access_token` value. So how can I retrieve it through PHP?
