debugging - How to use Laravel 4 profiler correctly -

I am trying to improve the performance of some code in my site and found this profiler: < P> I have followed the guidance on the site and one of the site controllers has included the following:

  public function getTest () {$ logger = new profiler \ logger \ logger; $ Profiler = new profiler profile ($ logger); $ Profiler- & gt; StartTimer ('testLogging'); $ Data = paragraph :: select (array ('article.ede', 'article, newspaper,' article. Ijd_link ',' article title ',' article category ')) - & gt; Received () - & gt; ToArray (); Var_dump ($ data); $ Profiler- & gt; EndTimer ('testLogging'); Log: info ('Hello World!'); Echo $ profiler;   
 In the browser, I get the expected result and see the profile bar below.  
 I have a problem: In this basic test the profiler bar, when clicked is not open, so I am unable to see the logs etc. I'm not sure about why or how to go about fixing  
 If I remove the last echo then it works correctly.  
 However, I can not see the timer 'Test Leasing' in the toolbar.  
 Did I misunderstand a concept here?  
 How can I perform specific functions in my code and display results?  
 Thanks   
 
 
 To use the professor (Lute-Sharm / Profiler) In Laravel 4 properly you do not need to make an example example of the object.  
  $ logger = new profiler \ logger \ logger; $ Profiler = new profiler profile ($ logger); In these lorries, these beautiful things, called Facees, apply to Profiler so that you can call the profiler and log it like this:  
  public function getTest () {Profiler :: Start Timer ('Test Leasing'); $ Data = paragraph :: select (array ('article.ede', 'article, newspaper,' article. Ijd_link ',' article title ',' article category ')) - & gt; Received () - & gt; ToArray (); Var_dump ($ data); Profiler :: endTimer ('testLogging'); Log: info ('Hello World!'); }   
 This does not require you to resize the $ profiler, all output will be displayed automatically in the profile bar in the browser.  
 :  After Professor now it usually means that you are using a mask, it is important that you understand that the mask and $ Profiler are completely different - There are different institutions.  
 If you have not installed yet or the service provider does the following:  
 
 You first need to install a package with the composer, make sure you update the composer update  
 Add the next service to  
 ap / config / ap.php  
 in your composer.jason after adding "requirement".  
  
 Next Eddie  'Profiler Professor Service Provider',  Code> 'Profiler' = & gt; In the list of class aliens in the App / Config / APPPP, click on 'Profiler / Appes / Profiler',   
 Then enter  php artisan config: publish loic-sharma / profiler in console run < / Code>   
 You have completed that the above mentioned code should work completely.  
 To clarify what you did just wrong, you created a new installation; Profiler with the  new profiler logger \ loger;  If you had already set up the Fapas, the Profiler bar will already be displayed in the browser (will resonate) when you echo the  $ profiler;  You now have two profiles in your browser, open-ended issues arise, and when you do not resonate  $ profiler, the bar still appears because it will be displayed by you Not created one that is not displaying your output correctly.  
 If you still want to use Profiler's own instances:  
 
  'Profiler \ ProfilerServiceProvider' from the list of services,  Delete the provider in AP / Config / APPP  
  'Profiler' = & gt; In the app / config / apppp, the list of 'aliens' in the category of 'profiler apes \ proferrari',   
 then  php artisan dump-autoload  < / Li>  
 Then it will work:  
  public function getTest () {$ logger = new profiler \ logger \ logger; $ Profiler = new profiler profile ($ logger); $ Profiler- & gt; StartTimer ('testLogging'); $ Data = paragraph :: select (array ('article.ede', 'article, newspaper,' article. Ijd_link ',' article title ',' article category ')) - & gt; Received () - & gt; ToArray (); $ Logger- & gt; Debug (var_dump ($ data)); $ Profiler- & gt; EndTimer ('testLogging'); $ Logger- & gt; Information ('hello world!'); Echo $ profiler; }
