Stumped

[Thom McGrath]

Alright, I've run into a little problem. I have an html file with some
<?php ?> tags and such that need to be evaluated. Some of you probably
already know what I'm getting at.

I need to be able to open the file, make some changes, then execute the
code. I need it to behave like include() or require(). eval() was a
decent solution, but it only supports raw php code.

So what I'm doing is saving the modified code back out to a temp file,
calling include() on the temp file, and then deleting it. Seems like an
awful lot of work.

Is there a way to do this better? Basically an include() that I pass
code to rather than a file pointer?

Ok, I am a little confused, why nit just rename the .html file to .php and
do an include?
If that does not work, I may have a solution for you, but need to understand
you a bit better. can you give example?

or do you just want to eval() html and code? (this is possible)

eval() html and code. I can't do an include because the code is a bit
dynamic. It has HTML and PHP mixed in, like a web page file (as that's
pretty much what it is).

here is some code, I borrowed some pieces:
is will do the eval on a string with/embeded php tags

<?php

$s = "hi <?php print 'john doe'; ?>\n";

print gzenEval($s);

function gzenEvalBuffer($string){ob_start();eval("$string[2];");$return =
ob_get_contents();
ob_end_clean();return $return;}
function gzenEvalPrintBuffer($string) {ob_start();eval("print
$string[2];");$return = ob_get_contents();
ob_end_clean();return $return;}
function gzenEval($string){$string =
preg_replace_callback("/(<\?=)(.*?)\?>/si","gzenEvalPrintBuffer",$string);
return
preg_replace_callback("/(<\?php|<\?)(.*?)\?>/si","gzenEvalBuffer",$string);}

?>

But wouldn't that screw up the scope, because the eval is being
executed inside a function?

for emaple:
$name = 'john doe';
$s = "hi <?php print $name; ?>\n";
print gzenEval($s);

wouldn't that simply output

'hi '

?

nope, I tested before I posted, it works ok, this use to be part of my
encoders, now I moved all static html into encoded php, so I didn't need
this stub anymore, but thats another story

oops, I just saw what you typed: $name = 'john doe';
$s = "hi <?php print $name; ?>\n";

$s will be "hi <?php print john doe; ?>\n"
do a print $s; to verify

you would have to do this:
$name = 'john doe';
$s = "hi <?php print \"$name\"; ?>\n";
print gzenEval($s);

now if you wanted to eval the $name durring the eval process this can be
done, bu why, when you can do it before it hits it, since everything is in a
string.

Ok, but if you must, this too can be done, (I do it in my encoder, so an
encoded file can included a non encoded file).

Lets make things real simple, can you post a mini version of what you are
doing, not theory, but bits-o-code?

One last question regarding this code. The regex looks too greedy. For example:

$s = 'Hi <?php print 'John Doe'; ?>. How are you this <?php print
date('l'); ?>?';

Wouldn't that cause trouble? Unless I'm missing something, the regex
would match from the first <?php to the second ?>.

No, I can't. It's a) rather protected and b) rather complex. What I can
tell you is that this is for a template engine. My users would have the
ability to do something like $theme->ReadTemplate("Site Header"); to
load the site's header into some variable.

The header may contain php code embedded with plain html, so printing
the variable won't work. The other possibility is that the template
will contain pure php code which can be loaded a similar way. Although
a dumb possibility, I can't control what my users will want to do.

So I want to provide my users a function like

Execute($theme->ReadTemplate("Site Header"));

to handle this. There is a good possiblity that the code in the
template will need variables not in the template. So what I am doing
now is rather messy:

include(MakeInclude($theme->ReadTemplate("Site Header")));

which takes care of the job, but every time the template is needed, a
temp file will be created/overwritten, then included.

I am under the impression what I'm doing now might be the only or best
option, but I'm hoping somebody will have something better.

OK, so, would it be fair to say this:

$name = "john doe";

$s = "<B><?php print \$name; ?></B>"; // only \$ needed for direct string
not from file()
or
$s = file("localfile.template");

magicEval($s);

and you would like to have $name evaled in the magicEval, thus including a
file would work?

if so, let me know, email me at: info at gzentools dot com

The cleanest way is probably to do a
include("http://localhost/code.php?some_params...") where code.php outputs
the code. Makes it easier to debug since you can just call up the PHP code
in your browser.

Be sure to compare $_SERVER['SERVER_ADDR'] to $_SERVER['REMOTE_ADDR'] so
that you don't reveal your PHP code to the world!
