Depends on the version of Laravel:

Laravel 3:
----------

    $session_id = $_COOKIE[&quot;laravel_session&quot;];



Laravel 4.0:
---------- 

*Just not versions 4.1 and above:*

    $session_id = session_id(); //thanks Phill Sparks


Laravel 4.1 (and onwards):
----------

    $session_id = Session::getId();

or

    $session_id = session()-&gt;getId()

Laravel no longer uses the built-in PHP sessions directly, as a developer could choose to use various drivers to manage the sessions of visitors (docs for [Laravel 4.2][1], [Laravel 5.1][2], [Laravel 5.2][3]).

Because of this, now we must use Laravel&#39;s `Session` facade or `session()` helper to get the ID of the session:



  [1]: http://laravel.com/docs/4.2/session#configuration
  [2]: http://laravel.com/docs/5.1/session#introduction
  [3]: http://laravel.com/docs/5.2/session#configuration

Just had a little hunt for myself, 
because the above answers didn&#39;t work for me (Laravel 4.1)...

Had to use this: 

    Session::getId();

in laravel 5.5 first write this in your controller `use Session;`
and inside your controller function write the following line`session()-&gt;getId();`

I have a fresh installation of Groovy 2.1.4 and I&#39;d like to create a script that uses HTTP builder.

I&#39;ve added the following line at the top of the script:

    @Grab(group=&#39;org.codehaus.groovy.modules.http-builder&#39;, module=&#39;http-builder&#39;, version=&#39;0.6&#39;)

When I run the script in GroovyConsole, I get the following error:

    1 compilation error:
    
    Exception thrown

I get the same error, i.e. `not found`.

When I instead try to download the latest version, i.e. 1.1.3, via the appropriate command, it works. But even after that, resolving the http-client still fails.

Where&#39;s the problem?

I want to get the id of the session in Laravel 4

In Laravel 3, it was a bit hacky, but possible with this code:

    $session_id = Session::$instance-&gt;session[&#39;id&#39;];

But I can&#39;t work it out in Laravel 4... referencing the `Session::$instance` object throws errors: 

&gt; Access to undeclared static property: Illuminate\Support\Facades\Session::$instance

have tried:

    $session_id = Session::get(&#39;id&#39;);

but to no avail.. any ideas?

I know that I have downloaded a `Symfony2` project and started with but I have updated my vendor several times and I want to know which version of symfony I have 

Any idea ?

How to know which version of Symfony I have?

Every now and then I see **vendor** being used in a directory structure on web apps.

Like this:

    &lt;script src=&quot;js/vendor/modernizr-2.6.2.min.js&quot;&gt;&lt;/script&gt; 

What does this mean? Why do people use it?

More importantly, should _I_ use it? I make web apps using php and javascript.

I&#39;m trying to add a condition using a JOIN query with Laravel Query Builder.

&lt;!-- language: php --&gt;

    &lt;?php
    
    $results = DB::select(&#39;
           SELECT DISTINCT 
              *
              FROM 
                 rooms 
                    LEFT JOIN bookings  
                       ON rooms.id = bookings.room_type_id
                      AND (  bookings.arrival between ? and ?
                          OR bookings.departure between ? and ? )
              WHERE
                    bookings.room_type_id IS NULL
              LIMIT 20&#39;,
        array(&#39;2012-05-01&#39;, &#39;2012-05-10&#39;, &#39;2012-05-01&#39;, &#39;2012-05-10&#39;)
    );


I know I can use [Raw Expressions][1] but then there will be SQL injection points. I&#39;ve tried the following with Query Builder but the generated query (and obviously, query results) aren&#39;t what I intended:

    $results = DB::table(&#39;rooms&#39;)
        -&gt;distinct()
        -&gt;leftJoin(&#39;bookings&#39;, function ($join) {
            $join-&gt;on(&#39;rooms.id&#39;, &#39;=&#39;, &#39;bookings.room_type_id&#39;);
        })
        -&gt;whereBetween(&#39;arrival&#39;, array(&#39;2012-05-01&#39;, &#39;2012-05-10&#39;))
        -&gt;whereBetween(&#39;departure&#39;, array(&#39;2012-05-01&#39;, &#39;2012-05-10&#39;))
        -&gt;where(&#39;bookings.room_type_id&#39;, &#39;=&#39;, null)
        -&gt;get();

This is the generated query by Laravel:

    select distinct * from `room_type_info`
        left join `bookings` 
    on `room_type_info`.`id` = `bookings`.`room_type_id` 
    where `arrival` between ? and ? 
        and `departure` between ? and ? 
        and `bookings`.`room_type_id` is null

As you can see, the query output doesn&#39;t have the structure (especially under JOIN scope). Is it possible to add additional conditions under the JOIN?

How can I build the same query using Laravel&#39;s Query Builder (if possible) Is it better to use Eloquent, or should stay with DB::select?

A JOIN With Additional Conditions Using Query Builder or Eloquent

Why is this not working? 

    Article::with(&#39;category&#39;)-&gt;find($ids)

I got a Array to String Conversion Exception.

But if i split the query into 2 parts like this:

    $articles = Article::with(&#39;category&#39;)
and

    $articles = $articles-&gt;find($ids)

I didn&#39;t get any exception and the result is right.

In Laravel, there appears to be a command for creating a migration, but not removing.

Create migration command:

    php artisan migrate:make create_users_table


If I want to delete the migration, can I just safely delete the corresponding migrations  file within the database/migrations folder?

Migrations file:

    2013_05_31_220658_create_users_table


Safely remove migration In Laravel

I want to sort multiple columns in Laravel 4 by using the method `orderBy()` in Laravel Eloquent. The query will be generated using Eloquent like this:

    SELECT *
    FROM mytable
    ORDER BY
      coloumn1 DESC, coloumn2 ASC

How can I do this?

How to Use Order By for Multiple Columns in Laravel 4?

I have read laravel 4 docs about eloquent and was quite intrigued by the push() part.
It says, 

&gt; Sometimes you may wish to save not only a model, but also all of its relationships. To do so, you may use the push method:
&gt;
&gt; Saving A Model And Relationships
&gt;
&gt; `$user-&gt;push();`

[See link here](http://laravel.com/docs/eloquent)

Sorry but it&#39;s a bit blurry on my part the difference between save() and push().
I am hoping someone can clear this one out for me. Thank you.




Eloquent push() and save() difference

I&#39;m trying to understand the best place to put a global function in Laravel 4. For example, date formatting. I don&#39;t think making a facade is worth it as facades are too modular. I&#39;ve read articles about creating a library folder and storing classes there but that also seems like a lot for a simple function. Shouldn&#39;t a &#39;tool&#39; like this be available in Blade templates?

What are the best practices for something like this and how do I make it available to Blade templates?
