Analysis Method of PHP code performance

Performance analysis of PHP code.

You can use Xdbug to analyze.

But a better choice is Facebook's performance analysis tool, Xhprof.

It can be graphically structured. The premise is that you installed the GD library, you may also encounter some minor problems. I remember to update the Linux image Library.

Install xhprof extension: pecl install xhprof.
