Author Joshua Mostafa takes users through the versatile and powerful programming language known as PERL, a server side language whose primary duty is to handle dynamic content and service clients on the Internet. What separates PERL from other scripting languages is its flexibility. Users don't need to code in a certain way to effectively use PERL and have fun doing it. Joshua shows you what tools you need to get started in PERL and what resources to visit in order to perfect your scripting. Start learning now by clicking one of the topics below!
