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

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';

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.

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

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>

Saving it to a file and then redirecting the user to that file so it will

I would have to agree.

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

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.

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);
?>
----------------------

as it seems uncessary to have to write the page to disk just to include

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 ;)

Re: using echo but need something to execute php code

Well, I thought I was clear enough. I think what happens is because I use a
simple example that many here think there must be a simple solution. I give
a simple example only to express the problem as concisely as I can instead
of cluttering it up with things that are irrelevant and, I would assume,
only cause more confusion. Its like a math problem, If there is something
I'm trying to solve but the equation is very complicated and I can reduce
the issue down to a similar but much more simple problem then thats what I
would do. I believe my original explination was simple and explained the
problem but I could be wrong. I have gotten a solution from Janwillem which
probalby will work(haven't tried it yet due to other issues).

If it was simple as using include then I would have done it. Peopl elike
Toby and Geoff have a very simplistic view of things and there problem is
that their ego always ends up showing up.

In any case, again, I have a file that is essentially html code in it. It
has a php extension as all my files do. That is not the issue.

The issue is that I have this file, call it MyFile.php and I want to parse
it to modify some html code or generate some html code based on some
context. If I just use include then I have no way of looking at the file?

If I do

include 'MyFile.php'

Then how am I going to modify what I need to modify? Theres no way to get at
the contents of the file that is loaded do do anything.

For example, what if MyFile.php is

<body>
Hello
<div class="table"></div>
<?php
echo 'hello';
?>
</body>

REMEMBER THIS IS JUST A SIMPLIFIED EXAMPLE. Obviously if this was what I was
really trying to do there would be no need to parse it as I could approach
it differently. (so don't tell me I need to approach it differently because
its actually more complicated and maybe I did things backwards but its too
late at this point)

In any case, now I have a file called AddTable.php that essentially takes
this file and parses it for <div class="table"an d inserts a table inside
that div.

if I simply do

include 'MyFile.php'

then how can I parse it?

if I do

$file = file_get_conten ts('MyFile.php' );

Then I can easily parse the string $file and modify it to add the table.

so after that I now have $file that looks something like
<body>
Hello
<table>
<tr>
<td>Blah
</td>
</tr>
</table>

<?php
echo 'hello';
?>
</body>

and when I want to send it to the client,

echo $file;

it will not interpret the php code and just send it as text to them (so they
get exactly what is above in $file instead of

<body>
Hello
<table>
<tr>
<td>Blah
</td>
</tr>
</table>
hello
</body>

So I need a way to get $file to interpret the php code before I send it.
Janwillem has said eval will do it and from looking in the manual it seems
like it will work. There is also another solution I mentioned in the
original post that looks like it will work. I might have been able to design
the site differently and been able to avoid this issue but I didn't and I'm
not about to start over at this point just because some jack ass(not you)
gets to confused and doesn't understand the problem.

In any case I hope to try eval soon as I think it will be the easiest
solution and do exactly what I need.

Thanks,
Jon

There had to be an error somewhere ;]
"echo"ing, or "print"ing the output of "parse(&$Pa ge)" as defined won't work
as it doesn't actualy return anything.

I think eval() is going to be a little more complicated than you might
imagine, or I imagine perhaps.
However, may I suggest the following.
First, lets say your AddTable.php looks something like below;
also simplified;
--- begin AddTable.php
<?php
function makeTable(&$out put)
{
//simplified code to create the table output
$output='<table ><tr><td>tabl e stuff</td></tr></table>;
//$output now contains the table html .
}
//load MyFile into $output var below and call makeTable()
$output = file_get_conten ts('MyFile.php' );
makeTable($outp ut);
//$output now has the table html you want to display in the final
output.
echo $output; //echo'ing here will actualy happen at the place it is
included in the file below
?>
-----.end AddTable.php

----- begin Final HTML
<html>
<body>
<p>Hello<p>
<?php
include('AddTab le.php');
// AddTable.php is loaded here and the engine parses it immediately.
// After running the makeTable() function in AddTable.php it echo's
$output here
?>
</body>
</html>
----end final HTML

Final result;
<html>
<body>
Hello
<!-- output from include('AddTab le.php')
<table>
<tr>
<td>Blah
</td>
</tr>
</table>
--end output from the include
<?php
echo 'hello';
?>
</body>
</html>

I think this is what you want and a lot less complicated than eval().
