How to properly debug a php project?

Question

PHP

Good afternoon, please tell me how to properly debug a project, a project on opencart - the problem is that I can never reach a breakpoint, for example, there is a certain function, I put a breakpoint there, presumably there is a jamb in it, but my debugger opens with index php - from the very beginning and not from this point what am I doing wrong?

Answer 1

you have break at first line or break when script is outside the project in your settings, something like these flags are phpstorm in the settings
, you need to remove these flags and make settings if necessary, here's an example I even made a video like

Answer 2

Use a bunch of echo and var_dump .

echo '<pre>';
 var_dump($variable); 
exit;

You insert this into the place of interest and see what the variable contains. And so on until you find something wrong and the reason for this wrong.
