I am using PHP 5.3.8, therefore I can't use the latest Facebook SDK which works only with PHP 5.4.X.
given a url, I'd like my server to tell if this is a facebook-like-page, or not.
Do I have to use OAuth? I used to use the graph-api, but now I get all weird errors. like no access-token provided, no authorization etc.
My code was using cURL with GET and accessed https://graph.facebook.com/.urlencode("THE_PAGE_URL");
I don't know if this is not an overkill to do a whole authorization from my server, and if so, to whom? I must say I am lost in the facebook documentation, frankly.
I tried this sample code from Facebook, which does not work at all.
Is there a simple way to get info about a public like-page from facebook?
An easy way to make calls using the Facebook Graph API is with their Graph API Explorer.
You have to be logged into your Facebook developer account to access it obviously, but it is really helpful if you're experimenting with making different calls to a Facebook page.
Regarding oAuth, I would also highly recommend that you obtain a permanent page access token. It's the best way to mitigate the complexities of Facebook's oAuth process.

So I'm trying to get the latest tweets posted by a user using a PHP script (and caching the results into a text file). I'm using the request https://api.twitter.com/1/statuses/user_timeline.json?count=5&screen_name=google and it's been working fine as a public client, but in order to get better control over my API hit limit I need to authenticate my requests.
I've tried the method shown at https://dev.twitter.com/docs/auth/application-only-auth , but after I successfully connect I get the error "Your credentials do not allow access to this resource" (why ?). So I've tried to use the OAuth method (which looks frighteningly complicated for a hobbyist like me), and downloaded the TwitterOAuth library. But I'm still having trouble connecting ! I put my credentials in the config.php file, but I have no idea where to go from there. The documentation seems to be hinting that I need to manually login to Twitter to authorize the application's connection token... or something. Apparently I need to redirect to some callback URL (what even ?!) and get a short-term connection to enable a long-term connection password which I have to store for later ? What is this madness ?
I was initially under the impression that I could just fetch data from Twitter's RSS feeds but those can't be accessed from scripts for some reason (unlike the Google News RSS feed which fetches just fine). It seems I've gotten myself into something much more complicated than what I signed for. Isn't there an easier (and saner) way of doing this ? Or is nothing decidedly simple ?
I apologize for being such an easily-confused dullard, but my head is spinning.
Thanks !
Edit : after digging around some more I decided to just use PHP curl to fetch the raw page, and then do some Xpath voodoo to get the tweets and the time they were posted at. Of course, this is CPU-intensive, far from stable, and probably not a practice that pleases the folks at Twitter; it also only returns the last 20 tweets (which is thankfully enough for my needs).
However, Cormac Driver's response below about Temboo is certainly a method I'll be investigating next time I need to do something like that.
Temboo provides a simple way of using OAuth to authenticate with Twitter. The process is broken down into two steps:
InitializeOauth. This step returns a Twitter authorization URL that Twitter account holders can visit to grant access to your script.
FinalizeOauth. This step returns the access token that your script will need to make authenticated requests to the Twitter API on behalf of the user.
Full details on how to do this with PHP here: https://www.temboo.com/library/Library/Twitter/OAuth/
You can see an example of how Temboo handles OAuth for Facebook on this page. The PHP source code is provided, and it's almost identical to the code you'll need to do the same thing for Twitter.
(Full disclosure: I work at Temboo)
I need to grab the statuses from a Facebook page via PHP to display on the page. I don't want to have people logging in to facebook just for my script to grab the statuses from the page since it is a public page and isn't restricted. I have the Facebook API for PHP in my projects directory but have no idea how to use it to do what I want it to. Could someone give me a code example of how I'd do this? Thanks!
It's really a straight forward task if you follow the documentation. Since /PAGE_ID/feed requires any valid access_token, your app access_token is enough to get the data:
Open the Graph API Explorer (I'm querying coca-cola/feed)
Get an app access_token from the Access Token Tool and use it instead of yours
You're done!
I am trying to get a list of all Google Apps users of a domain onto a public PHP website (without visitors of the site needing to login or do anything). I have a basic understanding of what needs to happen but can't quite piece it all together. It can't be as hard as it seems to me... could it?
Authentication and Authorization:
I'm pretty sure it needs to use OAuth 2.0 ... but am unsure whether it needs 2 legged or 3 legged. I got another section of the site working with ClientLogin but that won't pull in Google Apps profiles, only user's first and last names (I need the other profile fields). I have set up the API access within the account and have that side of things all set (I believe).
I have found this page, which shows how to construct a URL request to get all Profiles (in every language except PHP of course) but don't understand how to implement this.
http://code.google.com/googleapps/domain/profiles/developers_guide.html
I also tried this example but it just gives me a 401 after I enter the credentials. http://gdatatips.blogspot.com/2008/11/2-legged-oauth-in-php.html
I don't know which frameworks or includes are needed to accomplish this either. I have tried zend, OAuth.php and a whole bunch of other bootstraps... but keep getting lost as to what each is doing.
If someone could help me by outlining:
Which files/framework I need to upload and include as a bootstrap
What variables within those files I need to update with the Google credentials
How I integrate the Google Profiles "Retrieve all Profiles" request with PHP
An ELI5 (explain it like i'm 5) overview would be very much appreciated... I'm sorry for my apparent incompetence, but I have been reading articles for nearly a week and have not gotten anywhere.
Thank you in advance for any help provided.
Good question.
You'll need to implement the Google OAuth 2.0 process as it's described here (experimental?), because someone (you) will need to give your app the initial permissions to access Google Apps API. Steps are:
Register your domain with google (don't remember the link)
Redirect/send browser to an authentication url: https://accounts.google.com/o/oauth2/auth, with the appropriate request params (see the first link). You'll need access_type=offline, your scope would be https://apps-apis.google.com/a/feeds/user/
Get a code back, then exchange for a refresh_token, an access_token, and a value specifying when the access_token will expire. Store these in a database
Whenever you need to make an API call, check if your access_token has expired or not, and refresh when necessary, which is what the refresh_token is for. The refresh_token is valid as long as you don't revoke the access you gave to the app.
OAuth Playground helps a lot. Good luck.
Seemingly it supposed to be https://github.com/facebook/php-sdk/. However, I am suspicious either it so because getLoginUrl method generates not the type of URL that is described in http://developers.facebook.com/docs/authentication/.
So I was wondering which of these is outdated?
The PHP SDK that you linked is up to date. It is a client for the various Facebook APIs, including the Graph API, the "old" REST API, and others. Right now, getLoginUrl() does generate a URL that has been used for longer than the OAuth documentation has existed, but the end result will be the same for you. If you do have a problem with that login URL for some reason, you're free to implement authentication any way you like by replacing or extending the existing SDK logic.
Remember, APIs and SDKs are not the same thing. The PHP SDK is just one API client. Everything in the official FB docs should be considered up-to-date, as they've all been revamped this year.
OAuth based authentication and Graph Api for data are the latest ones.

i like to post to my FB Fan Page, Some Content using cron job in PHP,How can i do that?
Can you gave me example?
After becoming familiar with the Graph API check out Facebook's documentation for Pages
