All you need is

error_log('你要输出的信息', 3, 'log文件路径');

Can

firephp

Error_log ($msg);
Trigger_error ($msg);
These two are the simplest, just go to the PHP error log to find the line

File_put_contents of complex points ($file _name, $msg, file_append);

Write error log, or exit breakpoint is incorrectly sent

The general framework has this method, if it is developed by itself to encapsulate a function is good. Read and write files. If only in the development phase, there is no need to output to log, directly var_dump to the page is good AH.
