I know this is not programming related question so to speak, but since we are programmers and we might use Netbeans for PHP development.
I am wondering how can I get in Netbeans interface with search, macro or some other way all lines that start with echo or print_r aka as debug lines.
Not sure what you mean with “…get in Netbeans interface with search…”.
To locate the lines, chose Find, tick the box regular expression, and enter
in the search box.
