内容説明
Using the proven Core Series format, this comprehensive introduction and reference gives experienced developers all the techniques and real-world code they need to master Perl -- fast! Start by examining Perl syntax from the perspective of an experienced programmer; learn Perl data types, built-in functions, modules, and object-oriented features. Discover how Perl communicates with the outside world; create network clients and servers; manipulate text and DBM files; and use Perl's portable database interface, DBI. Understand key issues of program maintenance and security in Perl environments; then learn how to use Perl as "the duct tape of the Web" -- via CGI scripting, Web clients, Apache mod_perl module programming, templates, and other techniques. For all sysadmins and Web developers who want to use Perl effectively, and already have a background in programming.
