Function for checking PHP profile / performance?

Question

I have no performance issues, however I would like to take a look at how long and how much memory it uses, etc.

I would like to understand firsthand what things can be the neck of bottles, etc., and improve any code that I could use or use ... (perfectionist)

I am looking to create a small function that I can call at the beginning and at the end of each function that writes:

• lead time
• memory used
• cpu require

any ideas?

I did not use such things as memory_get_usage () or time recording methods (), so I would like to get some tips on how to implement them together.

Try using XDebug to debug the code stream. XDebug will generate some file that shows how good your codes are, you can use Kcachegrind to render these files.
