Perl and PHP in general

[richardfangnail]

Is it true that the main advantage of using Perl or PHP is in making
forms for web pages?
Is that the basic gist of it?
Is that also true of Javascript?

No, no and no.

Forms for web pages are made using HTML.

By far the most common usage of Perl, that cannot be done with HTML, is
to write programs.

Although for PHP it is obviously true (you won't
and can't use PHP for anything else), the case
for Perl is very different.

There isn't such a difference at all.

Some examples:

PHP is a scripting language. True, it's focus is to handle Web-related
tasks, however it may be used for all sorts of things that have nothing
to do with the Web/HTTP.

In the context of the world wide web, Perl is used, for example, to process
the data input by forms, or as an interface between the web server and a
database. PHP is similar but more popular than Perl for WWW applications.
The forms are usually written in HTML and then the inputs of the forms are
passed to a Perl program. PHP can be embedded in HTML.

The reason to use Perl or PHP rather than HTML is that HTML has no control
flow. For example, it is impossible to do a branch (an "if" statement) in
HTML.

I know nothing about PHP but Perl is typically used to write programs while
HTML is used to describe text. I do not quite understand where you got the
idea that Perl and HTML have anything in common at all or that HyperText
Markup Language is a programming language to begin with.

Your question is like asking what is the most common usage of a pen that you
cannot do with a newspaper. Dude, it's writing maybe?

Not really, it's more that the HTML is embedded in PHP, since PHP is used
to parse the whole thingy.

The reason to use Perl or PHP rather than HTML is that HTML has no
control flow. For example, it is impossible to do a branch (an "if"
statement) in HTML.

*sigh* Both Netscape and MS have added horrible bad ideas to HTML, and
maybe you can even blame W3C for some major bad ideas in some of their
recommendations (which some call standards...).

Actually conditional comments are not a bad idea, it's way better then
relying on CSS hacks.

So instead of croaking with the other clueless frogs in the mud, educated
yourself.

I'll educateD myself when it's worthwhile. It doesn't matter if some of
these things are a good idea or not, as long as there are standards it
makes for a smoother experience for all .

And there you go wrong again: W3C hasn't published a single standard. They
publish recommendations and drafts. They are just a bunch of people from
various companies and institutions writing up some articles. And yes, some
are badly written, have mistakes, and others probably shouldn't have been
published in their current form in the first place.

Yet many people think they are a good thing, and keep calling their
publications "web standards".

Their is a web standard, it's called ISO HTML.

Guess what the S stands for...

Moreover, still some companies are able to have badly thought out ideas
added and implemented. The latest miracle comes from google, the nofollow
value that one can use with the rel attribute of the a element.
