1. Get file name, line number, function name
xdebug_call_class()
2. Output head information
xdebug_get_headers()
3. Output execution time
xdebug_time_index()
4. Code coverage
var_dump (xdebug_start_code_coverage());
5. Code tracking
xdebug_start_trace('trace');
The code to be traced...
xdebug_stop_trace();
The above introduces the basic use of the PHP extension xdebug, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
