Debug mode for Perl web development

It is quite disgusting to use Perl for web development and debug debugging information output. Unlike PHP, it can directly echo to the page, or eclipse directly breakpoint debugging. Perl can only output the information you want to display in a standard error, and view the information by viewing the log file.

The following uses Apache as the Web server for debugging.

Print stderr "this is my error data .";

The information you print will be output to the Apache error log. The default error log is in Apache/logs/error. log to see if it is already in it :)
