If you instantiated the `$team` variable outside of the function, then it&#39;s not in the functions scope. Use the [use][1] keyword.

    $team = Team::find($id);
    Mail::send(&#39;emails.report&#39;, $data, function($m) use ($team)
    {
       $m-&gt;to($team-&gt;senior-&gt;email, $team-&gt;senior-&gt;first_name . &#39; &#39;. $team-&gt;senior-&gt;last_name );
       $m-&gt;cc($team-&gt;junior-&gt;email, $team-&gt;junior-&gt;first_name . &#39; &#39;. $team-&gt;junior-&gt;last_name );
       $m-&gt;subject(&#39;Monthly Report&#39;);
       $m-&gt;from(&#39;info@website.com&#39;, &#39;Sender&#39;);
    });

*Note: The function being used is a [PHP Closure (anonymous function)][2] It is not exclusive to Laravel.*

I am looking for a simple code to create a WebSocket server. I found phpwebsockets but it is outdated now and doesn&#39;t support the newest protocol. I tried updating it myself but it doesn&#39;t seem to work.

	};

	// Log messages from the server
	connection.onmessage = function (e) {
	  console.log(&#39;Server: &#39; + e.data);
	};

If there is anything wrong in my code can you help me fix it? Console in Firefox says:

&gt;Firefox can&#39;t establish a connection to the server at ws://localhost:12345/.


How to create websockets server in PHP

While the [HTTP 1.1 spec](http://www.w3.org/Protocols/rfc2616/rfc2616.html) seems to _allow_ message bodies on [DELETE](http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.7) requests, it seems to indicate that servers should ignore it since there are no defined semantics for it.

&gt; **4.3 Message Body**
&gt;
&gt; A server SHOULD read and forward a message-body on any request; if the
&gt; request method does not include defined semantics for an entity-body,
&gt; then the message-body SHOULD be ignored when handling the request.

I&#39;ve already reviewed several related discussions on this topic on SO and beyond, such as:

* https://stackoverflow.com/questions/299628/is-an-entity-body-allowed-for-an-http-delete-request
* https://stackoverflow.com/questions/5905916/payloads-of-http-request-methods
* https://stackoverflow.com/questions/978061/http-get-with-request-body

Most discussions seem to concur that providing a message body on a DELETE may be *allowed*, but is generally not recommended.

Further, I&#39;ve noticed a trend in various HTTP client libraries where more and more enhancements seem to be getting logged for these libraries to support request bodies on DELETE. Most libraries seem to oblige, although occasionally with a little bit of initial resistance.

My use case calls for the addition of some required metadata on a DELETE (e.g. the &quot;reason&quot; for deletion, along with some other metadata required for deletion). I&#39;ve considered the following options, none of which seem completely appropriate and inline with HTTP specs and/or REST best practices:

* **Message Body** - The spec indicates that message bodies on DELETE have no semantic value; not fully supported by HTTP clients; not standard practice
* **Custom HTTP Headers** - Requiring custom headers is generally [against standard practices](http://my.safaribooksonline.com/book/-/9781449317904/4dot-metadata-design/id2829455); using them is inconsistent with the rest of my API, none of which require custom headers; further, no good HTTP response available to indicate bad custom header values (probably a separate question altogether)
* **Standard HTTP Headers** - No standard headers are appropriate
* **Query Parameters** - Adding query params actually changes the Request-URI being deleted; [against standard practices](https://stackoverflow.com/questions/2539394/rest-http-delete-and-parameters)
* **POST Method** - (e.g. `POST /resourceToDelete { deletemetadata }`) POST is not a semantic option for deleting; POST actually represents the *opposite* action desired (i.e. POST creates resource subordinates; but I need to delete the resource)
* **Multiple Methods** - Splitting the DELETE request into two operations (e.g. PUT delete metadata, then DELETE) splits an atomic operation into two, potentially leaving an inconsistent state. The delete reason (and other related metadata) are not part of the resource representation itself.

My first preference would probably be to use the message body, second to custom HTTP headers; however, as indicated, there are some downsides to these approaches. 

Are there any recommendations or best practices inline with REST/HTTP standards for including such required metadata on DELETE requests? Are there any other alternatives that I haven&#39;t considered?

I&#39;m trying to use the Mail Class in Laravel 4, and I&#39;m not able to pass variables to the $m object.

the $team object contains data I grabbed from the DB with eloquent.

    Mail::send(&#39;emails.report&#39;, $data, function($m)
	{
	   $m-&gt;to($team-&gt;senior-&gt;email, $team-&gt;senior-&gt;first_name . &#39; &#39;. $team-&gt;senior-&gt;last_name );
	   $m-&gt;cc($team-&gt;junior-&gt;email, $team-&gt;junior-&gt;first_name . &#39; &#39;. $team-&gt;junior-&gt;last_name );
	   $m-&gt;subject(&#39;Monthly Report&#39;);
	   $m-&gt;from(&#39;info@website.com&#39;, &#39;Sender&#39;);
	});

For some reason I get an error where $team object is not available. I suppose it has something to do with the scope.

Any ideas ?

I&#39;ve been searching for a solution but it&#39;s seem I can&#39;t get it right, no matter what I try.  
  
After successful login, the user should be redirected to the page he came from, let&#39;s say he&#39;s been browsing a post and wants to log in so he can leave a comment, so he should be redirected to the post he was browsing. So here is what I have:

**login.php** shows the login form:
    
    &lt;form method=&quot;post&quot; action=&quot;login-check.php&quot;&gt;
    ... //input for username and password
    &lt;/form&gt;

The **login-check.php** checks if the username and pass are entered, does the user exist, or if he&#39;s already logged in, and a `p` parameter is sent to login.php:
    
    &lt;?php
    session_start();
    if((empty($username) OR empty($password) AND !isset($_SESSION[&#39;id_login&#39;]))) {
       header(&quot;Location:login.php?p=1&quot;);
       exit();
    }
    elseif (!user_exists($username,$password) AND !isset($_SESSION[&#39;id_login&#39;])) {
       header(&quot;Location:login.php?p=2&quot;);
       exit();
    }
    elseif(isset($_SESSION[&#39;id_login&#39;])) {
       header(&quot;Location:login.php?p=3&quot;);
       exit();
    }
    ?&gt;
  
then parameter `p` is sent back to **login.php** and displays the according message:
    
    &lt;?php
    if(isset($_GET[&#39;p&#39;])) {
      $p = $_GET[&quot;p&quot;];
	
      if($p==&quot;1&quot;)
        echo &quot;&lt;p class=\&quot;red\&quot;&gt;You didn&#39;t fill the form.&lt;/p&gt;&lt;br&gt;&lt;/br&gt;&quot;;
      if($p==&quot;2&quot;)
        echo &quot;&lt;p class=\&quot;red\&quot;&gt;User exists.&lt;/p&gt;&lt;br&gt;&lt;/br&gt;&quot;;
      if($p==&quot;3&quot;)
        header(&quot;Location: index.php&quot;);
    }
    ?&gt;

BUT, instead of going to index.php after successful login, it should go to the page the user has previously been. I&#39;ve tried in different ways but ether it doesn&#39;t work at all or it returns to login.php. It doesn&#39;t need to be super safe, because I&#39;m doing this for a school project.  
ALSO, I consider myself pretty novice, so please have patience :D

I&#39;m trying to find a fast way to remove `zero decimals` from number values like this:

    echo cleanNumber(&#39;125.00&#39;);
    // 125

    echo cleanNumber(&#39;966.70&#39;);
    // 966.7

    echo cleanNumber(844.011);
    // 844.011

Does exists some optimized way to do that?

How can I retrieve the raw executed SQL query in Laravel 3/4 using Laravel Query Builder or Eloquent ORM?

For example, something like this:

    DB::table(&#39;users&#39;)-&gt;where_status(1)-&gt;get();

Or:

    (posts (id, user_id, ...))

    User::find(1)-&gt;posts-&gt;get();


Otherwise, at the very least how can I save all queries executed to laravel.log?

I search the path where the *php.ini* file is located in our Linux Ubuntu server, and I found many *php.ini* files when executing the command `find / -name php.ini`. So how can I know exactly from a PHP script web page where the php.ini is located?




How can I know which &#39;php.ini&#39; file is used?

I want to rename a table in Laravel 4, but don&#39;t know how to do that.

The SQL is `alter table photos rename to images`. If there is an Eloquent solution, I&#39;d also like to know how to run a raw SQL, cause sometimes there&#39;s just no alternative.

Laravel 4: how to run a raw SQL?

I have got 2 joined tables in Eloquent namely themes and users.

**theme model:**

    public function user() {
      return $this-&gt;belongs_to(&#39;User&#39;);
    }

**user model:**

    public function themes() {
      return $this-&gt;has_many(&#39;Theme&#39;);
    }

My Eloquent api call looks as below:

    return Response::eloquent(Theme::with(&#39;user&#39;)-&gt;get());

Which returns all columns from theme (that&#39;s fine), and all columns from user (not fine). I only need the &#39;username&#39; column from the user model, how can I limit the query to that?

I am a beginner here so pardon me for this question am using `return File::put($path , $data);` to create a file in public folder on Laravel. I used this piece of code from controller I need to know the value of `$path` how should it be.

I know that I can access the environment value using the global `$env` variable, but is there *the right way* to get this value?

Laravel, how to get the environment value?

This seems like a pretty basic flow, and `Laravel` has so many nice solutions for basic things, I feel like I&#39;m missing something.

A user clicks a link that requires authentication.  Laravel&#39;s *auth* filter kicks in and routes them to a login page.  User logs in, then goes to the original page they were trying to get to before the &#39;auth&#39; filter kicked in.

Is there a good way to know what page they were trying to get to originally?  Since Laravel is the one intercepting the request, I didn&#39;t know if it keeps track somewhere for easy routing after the user logs in.

If not, I&#39;d be curious to hear how some of you have implemented this manually.

Laravel redirect back to original destination after login

My guess was to use the following syntax:

    MyModel::all()-&gt;delete();

But that did not work. I&#39;m sure it&#39;s super simple, but I&#39;ve searched for documentation on the subject and can&#39;t find it!
