HTML report generated in "./myreport7" directory

Done

I don't know why phpmetrics cannot analyze my files

Thanks

With my fix (only in PR), there is no more warnings, but I tried to parse an empty folder to reproduice. If your problem is actually PhpMetrics being unable to read your files, could you please share your "src/82files" content?

Otherwise, assuming this will be fixed.

Thanks a lot.

I can see that your project only contains PHP snippets without any classes nor any OOP objects. PhpMetrics is intended for projects with usages of packages, namespaces, classes, interfaces, and other structures like that.
The only metrics we could fetch from your project is the number of lines of code (total, logical and comments), but as they are not in classes, they will not be included in the reports.

If this is still a metrics you want to know about your project, I recommend you to use instead phploc from Sebastian Bergmann as it does the exact same thing PhpMetrics can offer you, as long as you don't use classes.

If you will to use classes, everything will be fine with PhpMetrics, as the following example shows you:

class F019
{
    public function __construct()
    {
        //[Your content of the file in "019" folder here]
    }
}
