Perl and DBI,cle, Sybase, Informix, MySQL, mSQL, Postgress, ODBC, and many others, even files with comma-separated values (CSV). With this module we can access and administer databases from our Perl programs, combining the power and enjoyment of Perl with the usefulness of databasing information.作者: PLIC 時(shí)間: 2025-3-23 13:12
Scalars,that tell us something we already know. Even more rarely do we write programs that do nothing interesting with our data at all. So, if we’re going to write programs that do more than say hello to us, we’re going to need to know how to perform computations, or operations on our data.作者: 津貼 時(shí)間: 2025-3-23 14:53
Lists and Arrays,g scalar variables into which we can store numbers and strings is nice—this allows us to write programs to manipulate data. However, scalars are somewhat limited since they can only contain a single value.作者: 針葉類(lèi)的樹(shù) 時(shí)間: 2025-3-23 19:55
Subroutines/Functions,spaces from a string, getting information into a hash in a particular format, and so on.

String Processing,s power in processing text is through its built-in regular expression support that we discussed in Chapter 7. Perl also has many built-in string operators (such as the string concatenation operator . and the string replication operator x) and string functions.

References,we discussed hashes in Chapter 5, we learned that hash values are scalars. Therefore, up to this point in our discussion of Perl, we have not been able to create arrays of arrays (also known as multidimensional arrays) or other more complex data types.作者: 惰性氣體 時(shí)間: 2025-3-24 13:39

https://doi.org/10.1007/978-981-10-6451-7Every programming language has a number of things in common. The fundamental concepts of programming are going to be the same, no matter what language in which you do them. In this chapter, we’ll investigate the things you need to know before you start writing any programs at all. For instance:作者: Ejaculate 時(shí)間: 2025-3-25 11:05

Tetsuro Kobayashi,Hitoshi OkadaIn Chapter 12 we discussed Perl’s object-oriented programming features.

Interfacing to the Operating System,Perl is a popular language for system administrators and programmers who have to work with files and directories due to the fact that there are many built-in functions to perform sys admin activities. These activities include creating directories, changing the names of files, creating links, and executing programs in the operating system.作者: 陳腐思想 時(shí)間: 2025-3-27 08:39
