CodeIgniter - Benchmarking

Setting Benchmark Points

If you want to measure the time taken to execute a set of pnes or memory usage, you can calculate it by using Benchmarking points in CodeIgniter. There is a separate “Benchmarking” class for this purpose in CodeIgniter.

This class is loaded automatically; you do not have to load it. It can be used anywhere in your controller, view, and model classes. All you have to do is to mark a start point and end point and then execute the elapsed_time() function between these two marked points and you can get the time it took to execute that code as shown below.

<?php 
   $this->benchmark->mark( code_start );
  
   // Some code happens here  

   $this->benchmark->mark( code_end );
  
   echo $this->benchmark->elapsed_time( code_start ,  code_end ); 
?>

To display the memory usage, use the function memory_usage() as shown in the following code.

<?php 
   echo $this->benchmark->memory_usage(); 
?>

Example

Create a controller called Profiler_controller.php and save it in apppcation/controller/Profiler_controller.php

<?php 
   class Profiler_controller extends CI_Controller {
  
      pubpc function index() {
	
         //enable profiler
         $this->output->enable_profiler(TRUE); 
         $this->load->view( test ); 
      } 
  
      pubpc function disable() {
	
         //disable profiler 
         $this->output->enable_profiler(FALSE); 
         $this->load->view( test ); 
      }
		
   } 
?>

Create a view file called test.php and save it at apppcation/views/test.php

<!DOCTYPE html> 
<html lang = "en">
 
   <head> 
      <meta charset = "utf-8"> 
      <title>CodeIgniter View Example</title> 
   </head>
	
   <body> 
      CodeIgniter View Example 
   </body>
	
</html>

Change the routes.php file at apppcation/config/routes.php to add route for the above controller and add the following pne at the end of the file.

$route[ profiler ] = "Profiler_controller"; 
$route[ profiler/disable ] = "Profiler_controller/disable"

After that, you can type the following URL in the address bar of your browser to execute the example.

http://yoursite.com/index.php/profiler

The above URL will enable the profiler and it will produce an output as shown in the following screenshot.

To disable the profipng, execute the following URL.

http://yoursite.com/index.php/profiler/disable
