⁠Alpine-Profiler

This Docker image extends :alpine-official to add XHProf profiler⁠. It actually uses an experminental fork of XHProf⁠ that works on PHP7.

⁠Usage

Use it in place of :alpine-official when you want profiling.

Add the following when you want to start profiling your code:

    xhprof_enable(XHPROF_FLAGS_MEMORY + XHPROF_FLAGS_CPU);

Add the following when you want to stop profiling:

    $name = time();
    $type = "my-app-1";
    $filename = "/var/www/profiles/$name.hub9.xhprof";
    file_put_contents($filename, serialize(xhprof_disable()));`

I recommend you mount the profiles directory on your host. Ie, in your docker-compose:

    app:
        image: tuimedia/base:alpine-profiler
        volumes:
            - ./profiles:/var/www/profiles

A note about naming: the XHProf UI is a piece of shit, but it works.

To use XHProf UI the profiles must be:

• named name.type.xhprof
• name must a hexadecimal digit that returns true when passed to ctype_xdigit
• type must be present
• The name and type must be separated by a dot
• The file extension must be xhprof

⁠Using the XHProf UI

There are a lot of UIs for XHProf. The simplest (hah) to setup is the UI included in XHProf. See https://hub.docker.com/r/tuimedia/xhprof-docker/⁠
