using echo but need something to execute php code

I have some code that loads up some php/html files and does a few things to
them and ultimately returns an html file with some php code in it. I then
pass that file onto the user by using echo. Of course then the file doesn't
get seen by the user.

Is there any command that essentially executes the code and then echo's it?

something that will take a string like

'<body>blah<?ph p echo 'Hello'; ?></body>' and actually interpret the php
code?

e.g., doing

echo '<body>blah<?ph p echo 'Hello'; ?></body>';

does me no good caues the php code isn't interpreted.

Saving it to a file and then redirecting the user to that file so it will be
executed seems like a roundabout way and causes more problems.
essentially I am trying to include php/html files in one another but I need
to do some parsing on them first. I'd rather not do something like
file_get_conten ts($Page)
parse($Page)
save($Page)
include "$Page"
as it seems uncessary to have to write the page to disk just to include it.

At

http://us2.php.net/include/
"Another way to "include" a PHP file into a variable is to capture the
output by using the Output Control Functions with include(). For example:"

Seems like I might be able to use that to replace when I use
file_get_conten ts to get the php code to execute?

Thanks,
Jon

For this specific case you could use eval:

$code = "?><body>blah<? php echo 'Hello'; ?></body>";
eval($code);

Note that the closing tag at the beginning of the eval string is mandatory.

Ok. Thats not the specific case I need but maybe it will still work? It is
essentially what I have. That is, I have an html file with some php code in
it similar to the example but just more complex. (actually right now its
just plain html but when I want to add some php stuff I'll need to be able
to have it evaluated).

Thanks,
Jon

Make sure the file has the extension of php.

Let me get this straight... you have an HTML+PHP file. You want your
script to open this file, run the PHP code inside and echo the whole thing
out to the client?

include 'file.php';

If you have an html file, that is, a file containing html markup with "html"
or "htm" extension it is _not_ parsed by the php engine,, normaly.
Is there any command that essentially executes the code and then echo's
it?
>
Yes, it's called "print" and it can do more complex things than echo will,
it's simlar, but not actualy the same.
It's described
here->http://www.faqts.com/knowledge_base/...l/aid/1/fid/40
something that will take a string like

'<body>blah<?ph p echo 'Hello'; ?></body>' and actually interpret the php
code?
Yes, there is.
-------------------------------------
!DOCTYPE blah blah blah
<html>
<head><title> </title></head>
<p>stuff in this file that contains html markup with a ".php" extension</p>
<p>Other stuff</p>
<?php
echo '<p>Parse this and include it into the html stuff above and
below</p>';
?>
<p>Other stuff in this file that has a ".php" extension and will be output
as html by the php engine.</p>
<?php
echo '<p>Parsed and included as html in the output with the other markup
around it</p>';
?>
<p>More html markup</p>
<?php
include(myFileI DidStuffTooAMom entAgo.inc);
?>
</body>
</html>
------------------------------------fileName.php
>
e.g., doing

echo '<body>blah<?ph p echo 'Hello'; ?></body>';

does me no good caues the php code isn't interpreted.
But would if you wrote it as below and saved the file with a php extension..
<body>blah
<?php
echo 'Hello';
?>
</body>
>

I would have to agree.

Parsing is a very generic term and may include opperations that have nothing
to do with html output, or php for that matter.
It can only be assumed that you mean "interprete d by the php engine" but you
seem to indicate something else by the context here.
>

file_get_conten ts($Page)
parse($Page)
save($Page)
include "$Page"
The above could be written into a file with a .php extension as;
---------------------
<?php
$Page = file_get_conten ts('somepath/Page.txt')
function parse(&$Page)
{
//Losts of parsing code here
}
parse($Page);
file_put_conten ts($Page);
?>
----------------------
>

it.

I would have to agree. So you might write the above as follows;
---------------------
<?php
$Page = file_get_conten ts('somepath/Page.txt')
function parse(&$Page)
{
//Losts of parsing code
}
parse($Page);
echo $Page;
[Or
print parse($Page);
Or
echo parse($Page);
]
?>
----------------------

I'm not sure that the above is usefull. There seems to be some confusion
about what exactly you are wanting to do.
It may be an inaquacey on my part, or it may be ambiguity on your part ;)

You may be wondering why you would want to put your files “into” the database, rather than just onto the file-system. Well, most of the time, you wouldn’t. In situations where your PHP application needs to store entire files, the preferred method is to save the file onto the server’s file-system, and store the physical location of the file in your database. This is generally considered to be the easiest and fastest way to store files. ...
