Problems with PHP calling position and number of lines

Now there is a situation where there is a class that can get the current row number and so on. be introduced at various locations on the page.

For example, when page A uses this acquisition method, it can get the current number of rows in which A calls this method. The same applies to pages B, C, and D.

Please tell me how to implement it with php. Thank you

Reflection?

You can refer to:

<code>$bt = debug_backtrace();
$file = __FILE__;
$line = "unkown";
if (isset($bt[0]) && isset($bt[0]['file'])) {
    $file = $bt[0]['file'];
    $line = $bt[0]['line'];
}
$fl=  '['.$file.':'.$line.']';</code>

Please refer to magic variables

<code>__LINE__
__FUNCTION__
__CLASS__
__METHOD__</code>
