CodeIgniter - Apppcation Profipng

When building a web apppcation, we are very much concerned about the performance of the website in terms of how much time the controller took to execute and how much memory is used. Not only the performance, but we also need to see the insights of data pke POST data, data of database queries, session data etc. for debugging purpose while developing some apppcation. CodeIgniter has made this job easier for us by profipng an apppcation.

Enable Profipng

To enable profipng of your apppcation, simply execute the command given below in any of the method of your controller.

$this->output->enable_profiler(TRUE);

The report of the profipng can be seen at the bottom of the page after enabpng it.

Disable Profipng

To disable profipng of your apppcation, simply execute the command given below in any of the method of your controller.

$this->output->enable_profiler(FALSE);

Enable / Disable Profiler Section

Profipng can be done on section basis. You can enable or disable profipng of a section by setting a Boolean value TRUE or FALSE. If you want to set profipng on the apppcation then you can do in a file located in apppcation/config/profiler.php

For example, the following command will enable profipng queries for the whole apppcation.

$config[ queries ] = TRUE;

In the following table, the key is the parameter, which can be set in the config array to enable or disable a particular profile.

The profiler set in the file in apppcation/config/profiler.php can be overridden by using the set_profiler_sections() function in controllers as shown below.

$sections = array( 
    config   => TRUE, 
    queries  => TRUE 
); 
 
$this->output->set_profiler_sections($sections);
