After three days, I finally completed the project. Let's make a summary and learn from history. When I was sure to use Perl to do this, an old bird in the company saw it and said to me, "Why don't you use C # To write? First, you are skilled and do not need to check the grammar. Second, didn't you go back to the primitive society from the 21st century? I don't have grammar intelligence, but I use Notepad.

1 line PerlSpeaking of Perl today, there is only one line of Perl Program .Various Programming Language Perl is famous for its abnormal ancient spirit. For example, I often write Perl programs that I don't understand.For example, although the program in this document is short, it is estimated that I will be dizzy after

Program scripts in the process of running, always encounter such a problem, we will anticipate some problems and prepare them for processing code, and some unpredictable. The good program should be able to deal with as many of the possible anomalies as possible, this article summarizes some methods to solve these anomalies, of course, Perl in this processing than other similar languages, but it will not be poor there. Before we start, let's take a sto

I. Introduction of the ModuleModule is the Perl package. The Perl object is based on a reference to the data item in the package.When you use object-oriented programming in other languages, you declare a class and then create an object (instance) of that class, and all objects of a particular class behave the same way, determined by the class method, and you can create a class by defining a new class or inh
