How to do it?

The idea is pretty simple, so, no worries!

You will need to define a variable at the very beginning of your project microtime() and one at the end.

After that you will need to subtract the end microtime variable from the start microtime variable and thats it.Also you can set the output value to only show the first 2 decimals.



Lets take a quick example of a use case.

You are building a project and something is slowing you down and you want to find out what exactly first.

You can calculate this with the script above to measure the php execution time of your script programatically and start from there.

You can wrap this snippet around any php script and get your execution time for that specific portion.

Here is a good example on what you could do with it:
