$tags=get_meta_tags("http://example.com/blog/my-awesome-blog-post");
print_r($tags);

trying to get metainfo of a page on my site http://example.com/blog/my-awesome-blog-post. Sharing two screenshots:

Dev instance error:

Local Instance:

Getting error like failed to open stream: Redirection limit reached, aborting. This is the error i am getting.

I tried with different urls (Except facebook). I am getting successful results.

Is there anyway i can achieve this functionality.

Answer 1

I don't know about your localhost but this is what I have deduced from your scenario.

Your website(or the page you are accessing) keep redirecting to a new URL every time PHP tries to access the url. When, the limit of max redirection i.e. 20 is reached PHP stops following and gives you the error.

This is happening because PHP request is a simple http request which is not handling any session/cookies values. So, Your website always treats it as a new request and keeps redirecting.

To verify, Please note that when you open your URL(https://dev.kidengage.com/library) in a incognito window it redirects you to https://dev.kidengage.com/hyderabad to set location for the user. And, after cookies are set, no more redirections takes place for the given URL.

This is where redirections are happening.

So, you need to fix this first or write a custom CURL script to fetch the data which can handle the session as well as redirections.

Hope it would help.
