Including html files

[David Johnson]

I am looking for a way to combine the functionality of "include" and
"here documents" so that an included html file containing $variables
is expanded and handled (normally printed to stdout).

It would be something like:

print <<<HERE
include file.html;
HERE;

except that, of course, this won't work. The text "include
file.html;" will be printed and no file will be included. So it needs
to be some other syntax. Does php support this?

Simply use include....

....
....
include('file.h tml');
....
....

The text of the file will be inserted at that position and parsed as
normal html/php.

Re: Including html files

I don't think so. Or, at least, it doesn't work for me. I have two files:

hello.php:
<?php
$foo = "Hello, there";
include('header .html');
include('hello. html');
include('footer .html');
?>


hello.html:
<h1>$foo</h1>

I want the value of $foo to be printed when hello.html is included.
Instead, only the variable "$foo" is printed.

You have to change hello.html to either this:

<?php
print <<<BLOCK
<h1>$foo</h1>
BLOCK;
?>

or this:

<h1><?php print $foo; ?></h1>

Unless $foo is between <?php and ?> tags, it will be printed as normal HTML.

That's because you don't have the power of Bobo the Clown. Observe Bob in
action:

<?

// PHP 4.3.0+ required

define('ECHO_HE REDOC_START', "<?\necho <<<__BOBO_THE_C LOWN__\n");
define('ECHO_HE REDOC_END', "\n__BOBO_THE_C LOWN__;\n?>");

class PrintDocHereStr eam {
var $position;
var $data;

function stream_open($pa th, $mode, $options, &$opened_pat h)
{
// 'heredoc://<path to file>'
$filepath = substr($path, 10);
$this->data = ECHO_HEREDOC_ST ART
. file_get_conten ts($filepath)
. ECHO_HEREDOC_EN D;
$this->position = 0;
return true;
}

function stream_read($co unt)
{
$ret = substr($this->data, $this->position, $count);
$this->position += strlen($ret);
return $ret;
}

function stream_write($d ata)
{
$left = substr($this->data, 0, $this->position);
$right = substr($this->data, $this->position + strlen($data));
$this->data = $left . $data . $right;
$this->position += strlen($data);
return strlen($data);
}

function stream_tell()
{
return $this->position;
}

function stream_eof()
{
return $this->position >= strlen($this->data);
}

function stream_seek($of fset, $whence)
{
switch($whence) {
case SEEK_SET:
if ($offset < strlen($this->data) && $offset >= 0) {
$this->position = $offset;
return true;
} else {
return false;
}
break;

case SEEK_CUR:
if ($offset >= 0) {
$this->position += $offset;
return true;
} else {
return false;
}
break;

case SEEK_END:
if (strlen($this->data) + $offset >= 0) {
$this->position = strlen($this->data) + $offset;
return true;
} else {
return false;
}
break;

default:
return false;
}
}

function stream_stat()
{
return array( 'size' => strlen($this->data) );
}
}

stream_register _wrapper("hered oc", "PrintDocHereSt ream")
or die("Failed to register PrintDocHereStr eam");

$foo = "Hello, there";
include('header .html');
include('heredo c://hello.html');
include('footer .html');

Re: Including html files

Thank you for your solutions. I guess the answer is that there is
nothing native in php that supports such a "here-include." Pity,
because I think it would be quite useful.

Modifying the "hello.html " file to make it no longer straight html is
not an option since I want to be able to browse and edit it like an
html file.
Adding the snippet of php is the closest to what I had hoped for. It
would look a little strange in the html browser but not much.

The other solution, to me, is nothing short of amazing. If php can't
do it, then write your own. I question the interpretation time and
whether my ISP has the
latest version of php, but that may just be the way to go. Thanks.

Does anyone know if what I called "here-include" is in the php plan or
wish list?
And what it's really called?

Thanks.

How about this one?

Re: Including html files

Can I also execute php from within the quoted part of a form line?

hello.html:
....
<input type=text name=foo size=60 value="<?php print $foo; ?>">
....

[David Johnson]

Re: Including html files

Except it doesn't expand any variables in the file.
I want the file treated as if it were imbedded into
a here-doc so that all of the $foo variables in it are
replaced with their values.

Why do you want to use this approach? The "Here doc" approach. There are
already several available approaches to do what you probably want to do.
You seem to want to have your cake and eat it to. By this I mean in your
earlier post you said

"Modifying the "hello.html " file to make it no longer straight html is not
an option since I want to be able to browse and edit it like an html file.
Adding the snippet of php is the closest to what I had hoped for. It
would look a little strange in the html browser but not much."

But including PHP variables in the HTML will inherently make the page not
pure HTML!

So my suggestion is, USE TEMPLATES!

Try one of the following templating systems:

PHPFastTemplate - <http://www.thewebmaste rs.net/php/FastTemplate.ph tml>

Smarty - <http://smarty.php.net/>

bTemplate - <http://www.massassi.co m/bTemplate/>

(I personally prefer bTemplate -- easiest to set up, implement, and use.)

All three do basically the same thing: allow you to use pure HTML
templates that you can edit in, say, Dreamweaver or other WYSIWYG HTML
editor. And from my experience with bTemplate, I think it does something
very similar to what you are looking for as judging by your original post.

later...

Re: Including html files

what type of editor are you using where you can't
put <?=$stringvar ?> in it
any <xxxx> is a tag and therefore "straight html"
putting "$vars" in your document isn't "straight html." It's html
with "$vars" in it. What if you have javascript in your html file?
or $5.25 How's it supposed to know what $xxxx to ignore?

What do you mean the other solution is amazing "if php can't do it,
then write your own." What you mean if php doesn't have a predefined
function then write your own IN PHP. PHP gives you the tools, not
the finished house.

Re: Including html files

Uh.. No.
readfile doesn't parse the output at all..
it's a straight passthru to the output buffer.

First of all, why would you ever want to include() an HTML file?
readfile() is faster...

Second, HTML files are not supposed to be "containing $variables";
only PHP files are.

Third, what you seem to want is probably achievable with eval(),
although I am still at a loss what it is you are trying to accomplish
in such a convoluted way...

The 'include' approach should work fine. I've tested!


*** foo.php
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head><title> </title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>

<?
$name='John Smith';
include 'foo.txt';
?>

</body>
</html>

*** foo.txt
My name is <?=$name?>
[color=blue]
> <h1>$foo</h1>[/color]

That's why <? ?> tags exist. Otherwise, how could you tell what's PHP code
and what isn't? ;-)

Sounds like I wouldn't since it doesn't support what I want to do.

That's fine but it doesn't support $variables.

Not supposed to? There's nothing in the HTML spec that prohibits
text from containing dollar signs.

Only convoluted if php doesn't support it in a simple function call.
Which appears to be the case. Funny how it takes longer for people to say
"I don't know" than almost anything else.

For your information, I am trying to do bare-bones templates. I know
there are several fine template packages, but I don't want all the
function or overhead they provide. I want to put all of my html in
one file with variable names instead of text. The html would never be
displayed as such so no one but me would see the variable names.
But I want to use an html editor to edit these files and be able to
display them in a web browser. My php program would then "include" the
html file, substituting text for the variables.

php comes very close to supporting this. An included file can contain
php and a here-doc but that spoils it for display by a web browser.
If you could imbed an external text file while you're in a here-doc,
you could get what I'm looking for. But, of course, everything in a
here-doc is interpreted as straight text, not commands.

Maybe there is another way to do it, such as with an eval. But, as
you say, it tends to get convoluted.
