Retrieve a Get Http request in php - php

Question

I need to retrieve a get http request in php and store it in a variable.
I need to execute the following:
https://graph.facebook.com/oauth/access_token?
client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&
grant_type=client_credentials
I know this is simple. just not able to get my head around it.

Answer 1

$content = file_get_contents('https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials');

Answer 2

Within the Open Graph protocol page on Facebook, there is an example within the documentation coded using PHP: http://developers.facebook.com/docs/opengraph/
<?php
$ogurl = "INSERT_YOUR_OG_URL_HERE";
define(FACEBOOK_APP_ID, "YOUR_APP_ID_HERE");
define(FACEBOOK_SECRET, "YOUR_SECRET_KEY_HERE");
$mymessage = "Hello World!";
$access_token_url = "https://graph.facebook.com/oauth/access_token";
$parameters = "grant_type=client_credentials&client_id=" . FACEBOOK_APP_ID ."&client_secret=" . FACEBOOK_SECRET;
$access_token = file_get_contents($access_token_url . "?" . $parameters);
$apprequest_url = "https://graph.facebook.com/feed";
$parameters = "?" . $access_token . "&message=" . urlencode($mymessage) . "&id=" . $ogurl . "&method=post";
$myurl = $apprequest_url . $parameters;
$result = file_get_contents($myurl);
// output the post id
echo "post_id" . $result;
}
?>
The key line in actually making the call being:
$result = file_get_contents($myurl);
There is also a good amount of other information about the resulting object you get back there that would be good to take a look into.
Hope this is helpful.

if ($fp = fopen('https://graph.facebook.com/oauth/access_token?
client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&
grant_type=client_credentials', 'r')) {
$content = '';
// keep reading until there's nothing left
while ($line = fread($fp, 1024)) {
$content .= $line;
}
// do something with the content here
// ...
} else {
// an error occured when trying to open the specified url
}

Answer 4

You mean something like
$client_id = $_GET['client_id'];
$client_secret = $_GET['client_secret'];
$grant_type = $_GET['grant_type'];
?
Or rather something like
$content = file_get_contents($url);
?

Answer 5

Use the following
$id = $_GET['client_id'];
$type = $_GET['grant_type'];
$secret = $_GET['client_secret'];
Hope this helps you
