How to write a PHP error "line number" or complete error message into the file

All you can do now is write the number of rows of SQL errors into a text file

How do I write the wrong number of lines in the same way? Or would you like to write the entire PHP error message in the file?

The solution gives a big direction.

The solution gives a big direction.

1. Exceptionload the error with the object and throw it out
2. The outermost use try catch or set_exception_handler capture, the output of friendly errors while recording Exception information (including the full callstack, which has all the parameters, may be very large need to streamline)
3. Error can be converted to ErrorException walk the same processing

For example, I plant through MongoDB to record the log, which is a certain day error

Landing judgment is not accurate, trust return results have OpenID caused by notice, do not look at the code can see it

Error_log (), can you?
