Capture the calling file and line number that called my function

You might look at stacktrace, I did similar a while back to get a calling class name, adapt as needed:

<?php

namespace App\Helpers;

class DBS
{

    public static function __callStatic($method, $params)
    {
        $trace = debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS, 2);
        
        if (isset($trace[1]['class'])) {
            $class = $trace[1]['class'];
            $slh = strrpos($class, "\") + 1;
        } else {
            return null;
        }
        $model = "\App\Models\SMVC" . "\" . substr($class, $slh, -10) . "Model";
        $instance = new $model();

        return call_user_func_array(array($instance, $method), $params);
    }


}

https://github.com/filp/whoops does a pretty good job at this.

Maybe you can "borrow" a few ideas from those :-)

Thanks, I thought this might be more of a php question than a Laravel one. I just wondered if they had a handy package.
