运行url并从结果url-PHP获取参数值

In PHP, I have created an url something like below:

https://example.com/as//authorization.oauth2?pfidpadapterid=ctct&client_id=1234567890&redirect_uri=https://localhost&response_type=code&scope=contact_data&

When I load that url, I got the code in the resulting url like:

https://localhost/?code=abcd-1111-0000-ffgh

And the parameter code : abcd-1111-0000-ffgh is my required result.

So I have the request url and have to retrieve code from response url. How can I do this using PHP?

Can I use CURL for this? I tried but the curl return the request url itself.

Below is my code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $authURL); 
curl_setopt($ch, CURLOPT_HEADER, true); 
curl_setopt($ch, CURLOPT_NOBODY, true); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_exec($ch);
$new_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL); 
curl_close($ch);
return $new_url;

So my aim is to create an url(already done), run that url and get the parameter from the result url programmatically using PHP.

Try this :

You can get the URL parameters by using GET, for example

www.example.com/user?id=1111&Fname=john&Lname=Doe

...in your PHP : ...

$id=$_GET['id'];
$Fname=$_GET['Fname'];
$Lname=$_GET['Lname'];

I am not sure for what you are looking. This might help you

$context = [
    'http' => [
        'method' => 'GET',
        'max_redirects' => 5,
    ],
];

@file_get_contents('https://example.com/...//', null, stream_context_create($context));
echo '<pre>';print_r($http_response_header);die();

$http_response_header will be having location data
