CodeIgniter
Setting Benchmark Points
If you want to measure the time taken to execute a set of lines 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.
To display the memory usage, use the function memory_usage() as shown in the
following code.
echo $this->benchmark->memory_usage();
Example
Create a controller called Profiler_controller.php and save it in
application/controller/Profiler_controller.php
