Well for learning Perl, there is a book which's name surprisingly is Learning Perl ;-) I'd start with that, followed by the camel.

I would always use a Templating System, even for smaller projects. It saves you much debugging time. And you can learn them, especially TT, rather quickly.

As you have some PHP experience, Embedding Perl in HTML with Mason could be interesting for you. I personally prefer TT, for which I have some printable docu in PDF format on my homepage.

The answer to your last question:

perldoc -f require
[download]

Happy coding.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
