Better use [`$_SERVER[&#39;REQUEST_METHOD&#39;]`](http://docs.php.net/manual/en/reserved.variables.server.php):

    if ($_SERVER[&#39;REQUEST_METHOD&#39;] === &#39;POST&#39;) {
        // …
    }

Use [`$_SERVER[&#39;REQUEST_METHOD&#39;]`][1].

I installed [ReSharper][1], and it works in Visual Studio, but how can I disable it?

Whenever I search in the ReSharper menu, I can&#39;t find a disable option.

This is more of a &quot;why do things work this way&quot; question rather than a &quot;I don&#39;t know how to do this&quot; question...

So the gospel on pulling associated records that you know you&#39;re going to use is to use `:include` because you&#39;ll get a join and avoid a whole bunch of extra queries:

    Post.all(:include =&gt; :comments)

However when you look at the logs, there&#39;s no join happening:

    Post Load (3.7ms)   SELECT * FROM &quot;posts&quot;
    Comment Load (0.2ms)   SELECT &quot;comments.*&quot; FROM &quot;comments&quot; 
                           WHERE (&quot;comments&quot;.post_id IN (1,2,3,4)) 
                           ORDER BY created_at asc) 

It _is_ taking a shortcut because it pulls all of the comments at once, but it&#39;s still not a join (which is what all the documentation seems to say). The only way I can get a join is to use `:joins` instead of `:include`:

    Post.all(:joins =&gt; :comments)

And the logs show:

    Post Load (6.0ms)  SELECT &quot;posts&quot;.* FROM &quot;posts&quot; 
                       INNER JOIN &quot;comments&quot; ON &quot;posts&quot;.id = &quot;comments&quot;.post_id

Am I missing something? I have an app with half a dozen associations and on one screen I display data from all of them. Seems like it would be better to have one join-ed query instead of 6 individuals. I know that performance-wise it&#39;s not always better to do a join rather than individual queries (in fact if you&#39;re going by time spent, it looks like the two individual queries above are faster than the join), but after all the docs I&#39;ve been reading I&#39;m surprised to see `:include` not working as advertised.

Maybe Rails _is_ cognizant of the performance issue and doesn&#39;t join except in certain cases?

With error reporting on, or even for best practice, when unsetting a variable in PHP, should you check to see if it exist first (in this case it does not always exist) and the unset it, or just unset it?

    &lt;?PHP
    if (isset($_SESSION[&#39;signup_errors&#39;])){
    	unset($_SESSION[&#39;signup_errors&#39;]);
    }
    
    // OR
    
    unset($_SESSION[&#39;signup_errors&#39;]);
    ?&gt;

Is it safe to pass raw base64 encoded strings via GET parameters?

Passing base64 encoded strings in URL

The legitimate users of my site occasionally hammer the server with API requests that cause undesirable results. I want to institute a limit of no more than say one API call every 5 seconds or n calls per minute (haven&#39;t figured out the exact limit yet). I could obviously log every API call in a DB and do the calculation on every request to see if they&#39;re over the limit, but all this extra overhead on EVERY request would be defeating the purpose. What are other less resource-intensive methods I could use to institute a limit? I&#39;m using PHP/Apache/Linux, for what it&#39;s worth.

Is it possible in PHP to instantiate an object from the name of a class, if the class name is stored in a string?


Can PHP instantiate an object from the name of the class as a string?

Actually I have two questions.

(1) Is there any reduction in *processing power* or *bandwidth* used on remote server if I retrieve only headers as opposed to full page retrieval using php and curl?

(2) Since I think, and I might be wrong, that answer to first questions is *YES*, I am trying to get last modified date or If-Modified-Since header of remote file only in order to compare it with time-date of locally stored data, so I can, in case it has been changed, store it locally. However, my script seems unable to fetch that piece of info, I get `NULL`, when I run this:

    class last_change {

     public last_change;

     function set_last_change() {
      $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, &quot;http://url/file.xml&quot;);
        curl_setopt($curl, CURLOPT_HEADER, true);
        curl_setopt($curl, CURLOPT_FILETIME, true);
        curl_setopt($curl, CURLOPT_NOBODY, true);
      // $header = curl_exec($curl);
      $this -&gt; last_change = curl_getinfo($header);
      curl_close($curl);
     }

     function get_last_change() {
      return $this -&gt; last_change[&#39;datetime&#39;]; // I have tested with Last-Modified &amp; If-Modified-Since to no avail
     }

    }

In case `$header = curl_exec($curl)` is uncomented, header data is displayed, even if I haven&#39;t requested it and is as follows:

    HTTP/1.1 200 OK
    Date: Fri, 04 Sep 2009 12:15:51 GMT
    Server: Apache/2.2.8 (Linux/SUSE)
    Last-Modified: Thu, 03 Sep 2009 12:46:54 GMT
    ETag: &quot;198054-118c-472abc735ab80&quot;
    Accept-Ranges: bytes
    Content-Length: 4492
    Content-Type: text/xml

Based on that, &#39;Last-Modified&#39; is returned.

So, what am I doing wrong?
