Extract value from an array in php -

-

In my code, $ returns an array of data that is trying to remove the [2] value in that array I am For some reason it gives the entire array instead of just the value that I am trying to remove. I think it's really simple and I'm just looking at something.

Here's my code: 

  $ url = 'https://sandbox.familysearch.org/ forum / tree / person / KWWM-5R1 / Portrait? Access_token = '$ _SESSION [' FS-session ']; $ Return = print_a (get_headers ($ url)); $ Return return [2];

and there is a harvesting from the array printed here: 

  array ([0] => HTTP / 1.1 307 temporary redirection [1] = & Gt; Server: Apache-Coyote / 1.1 [2] = & gt; Location: https://integration.familysearch.org/sandbox/v2/TH-501-48051-27-34/thumb200.jpg?ctx= ArtCtxPublic)

How can I get the [2] value? Try to get rid of print_r 

  $ return = get_headers ($ url); $ Return return [2];

print_r is a function used to print information from a variable (your array, in terms of its content). You want that instead of the header add, you set the value of $ return to print_r as the return value (which is just true ).

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
