Is a PHP variable supposed to be seen in a .js file included into a .php file

[aa]

Is a PHP variable supposed to be seen in a .js file included into a .php
file?

I have a client side javascript code stored in a .js file which is included
into a PHP file using
<script src="filename.j s></script>

This code initialises a Javascript variable
var u="string";

The string is supposed to be the value of $HTTP_HOST

So, when initialise this variable like

var u=<? echo $HTTP_HOST;?>;

I sterted getting a javascript message Syntax Error

Am I doing something wrong, or PHP variables are not seen in included js
files?

js files are not parsed for PHP code unless you specifically tell the
webserver to do so. Therefore, "var u=<? echo $HTTP_HOST;?>;" in the .js
will error since the browser doesn't know what to do.

You need to modify your web server configuration so that .js files are
parsed by PHP.
For Apache, use something like the following:

AddType application/x-httpd-php .js

Why not simply point the src to a php file, that way php isnt executed
for every other static js file. Just don't forget to set the correct
mimetype (application/x-javascript).

BTW TOFU is bad practice.

At the extreme risk of going way off topic...

I believe that TOFU actually makes much more sense.

When you convince google-groups to preview the BOTTOM 30 lines of a
message, I'll switch over..

I find it hard to understand how anyone who uses a modern, message
threading news reader can tolerate bottom postings... I'm sure someone
will let me know.. :-)

The fact that some people don't know how to snip when using the correct
form of posting doesn't justify you using an incorrect form.

Re: Is a PHP variable supposed to be seen in a .js file included into a .php file

You're right, that would work better :-)

However, you could also put the directive in a .htaccess file in the
directory with the dynamic js files.
I personally prefer to give files their correct extensions so I don't
lose syntax highlighting (etc) in editors that don't allow you to
manually specify a file's type.

Forgive my ignorance, what does TOFU stand for?

30 lines under a full overquote is just as bad (at least), if you write
a posting you should take the time to make a readable posting, it should
be short and summarize for readability (just in case some messages don't
make it or get delivered out of order). TOFU or bottom posting are for
lazy people who write for themselves.

So whats the reason for the full underquote? Modern threaded readers
make it easy for the user to get the full message if they want it to!
TOFU makes no sense in this case, so just don't resend the same old
article so people don't have to scan in just in case there is something
added.

Saves time, because you don't have to endlessly scroll down or look up
in another posting what the author is referring to.

The usual (and for many people most readable) way is:
[color=blue]
>question[/color]

answer
[color=blue]
>question[/color]

answer

Like in any other discussion. Or do you wait until you got 5 questions
and then answer them all at once? If yes - how would you do this? Always
say something like "And now to your question about this and that"? Why
not simply answer/comment one question at a time?

Another thing that people writing top postings (BTW: what's TOFU in
English? I only know it in German ... *g*) seem to forget is the length
of the posting. With just adding an answer on top of another posting the
articles get longer and longer, hundreds of lines for just a handful of
new text. This wastes bandwidth and space on hundreds of newsservers.

You need to think about which side (client/server) is doing what. PHP is
running on the server. As far as PHP knows, that <script> tag is just
another HTML tag. It's just a string of text to be sent to the client.

By the time the client browser sees this tag, PHP is all done. The browser
makes another, separate request to the server to fetch the URL
"filename.j s". PHP is not involved in that transaction at all -- it's just
a simple fetch.

If you really need to so substitution in your .js file, then you need to
have it included in the PHP source, using something like this:

<script>
<? require( "filename.j s" ); ?>
</script>

That way, PHP will interpret the contents of the file and do substitutions.

PHP variables can only be seen in files that are processed by PHP.

Thanks, it never occured to me that the <script> tag can src any file, not
just .js

Regarding setting the correct mimetype (application/x-javascript) - where
do I set it?

Thank you very much, Tim, for the perfect explanation if the situation

Re: Is a PHP variable supposed to be seen in a .js file included into a .php file

"BTW TOFU is bad practice."

I don't care if the reply it typed at the top or at the bottom as long as it
is a non-bullshit reply.

I personally do not like scrolling down prevuious posting to get the reply
(I now suspect that the expression "to get to the bottom of something"
meaning to understand somethiong through hard labour, originated from
reading such threads :-) ).

But I do not feel like imposing my preferences on others and only call upon
the other not to raise similar discussions as they indeed clog the group.

Thenky everybody who replied both at the top and at the bottom.

Re: Is a PHP variable supposed to be seen in a .js file included into a .php file

Just one clarification, Tim

I thought that PHP first performs all include() and require() and only then
execute whateever is found incide <? ?> including substitutions. That is why
a variable declared in one included file is seen from the other included
file.

However by that token the code
<?
$fn="filename";
include ($fn);
?>
should not work because
include ($fn);
should be done BEFORE executing $fn="filename";

This is the case with ASP's #include directive
But it works in PHP which means that PHP execute PHP code on the hosting
page in the order it is written, adding included external files as it goes
and executing PHP on the included files as it goes through them.
Is that how it works?
