OOP, HTML Classes and implode() :/

Borior

Im using html classes and it looks like this:

$page->SetParameter ("PAGE_CONTENT", "Hello World!");

This (funnily enough :p) sets a parameter for the HTML class so that in the template file an instance of {PAGE_CONTENT} will be replaced with "Hello World!" .


I've got somewhere here:

for the include thing i can implode the file, like this:

$content = implode ('', file ('pages/example.php'));

and then call it like this:

$page->SetParameter ("PAGE_CONTENT", $content);

HOWEVER ... i still need help ... if example.php contains php (which it does) how do i parse the (imploded) $content variable ... as is, it doesn't parse and so calls like "$_SERVER['REMOTE_ADDR'];" do nothing.

Thanks in advance.

try ADDSLASHES to the content before you implode it.

see if that works

1) I'd love to know how that'll work. example.php has html too ... and adding slashes will screw that up.
2) How do i addslashes to a file that i have to include to reference without it printing out the contents before i want it to?

juschillinnow

oh, so try html_entities or htmlspecialchars

Borior

NOOOoo ... sorry, im not making myself clear ... it has PHP in it AS WELL

juschillinnow

oh, right. sorry bout that.

You'd think there'd be a function to do this, but I don't think so. Not to my knowledge anyways.

You may have to

explode("[<?,?>]", $contents);
then addslashes to the by products and join them in the end.

I think I have a function for that. Hang on.

You might want to have a look at the eval() function, it evaluates the string and runs it as if it was php code.

Also if you want to get the file as 1 big string use file_get_contents() instead of implode( '',file(....) );

HalfaBee

juschillinnow

right, but to use the eval, you still need to explode your "big" string by <? ?> . because you can only evaluate php

juschillinnow

nope, don't have a function, I used eval in it and make a php file out of my html contents.

But that won't work for you.

Sorry.

Guess you're going to have to explode until someone comes up with something better.

HalfaBee

How about

preg_match( "<\\?.*\\?>",$content,$phpbits );
foreach( $phpbits as $code )
    eval( $code );

you could do this

$to_eval = "?>" . $file_contents . "<?php";
eval($to_eval);

look ma a simple way to do something.

Borior

i don't seem to be able to get any of the examples to work ... can someone be clearer .... i want to be able to parse bits that are php and not bits that are html. I then want to return() ALL of it .. IN THE RIGHT PLACES ... so that something like

<p>
Your IP address is <?php echo $_SERVER['REMOTE_ADDR']; ?>
</p>

will actually say something like:

    Your IP address is 192.168.0.4

I don't have an example handy but you want is the output buffering routines.
http://www.php.net/manual/en/ref.outcontrol.php

Something like:

/* Start the buffering */
ob_start();

/* Let the script run */

/* Get all the output */
$result = ob_get_contents();

drawmack

my example explained:

<?php
$to_eval = "\$printme = ?> $file_contents <?php";
?>

what we have just done is created a string that say $printme is equal to the contents of the file. However we have prepended a ?> and postpended a <?php to the file contents. This will allow the php parser to ignore the html and process the php. forexample

File:

<?php echo 'hello world'?>

Script:

<?php
$to_eval = "\$printme = ?>$file_contents<?php";
?>

at this point $to_eval contains this "$printme = ?><?php echo 'hello world'?><?php". which may look a little stupid but is valid php.

Then you do this:

<?php eval($to_eval)?>

No $print me is equal to the contents of your file with the php executed. Then you do this

<?php echo $printme?>

and your web-page is displayed to the user.

I may be completely off track here, but why don't you include() the file?

Borior

i can't understand how it can be this difficult.

code like this:

$content = file_get_contents('pages/'.$p.'.php');

$to_eval = "\$printme = ?>$content<?php";
eval($to_eval);
echo $printme;

outputs NOTHING, while code like this:

$content = file_get_contents('pages/'.$p.'.php');

$to_eval = "\$printme = ?>$content<?php";
eval($to_eval);
//NOTE LINE BELOW
echo $to_eval;

outputs this:

$printme = ?>

before the (unparsed) content of my pages

HELP!

Borior

It may interest you to know that where "pages/$p.php" is the following:

<?php
if (isset($_POST['from'])) {

$ip = $_SERVER['REMOTE_ADDR']; 
$resolved = gethostbyaddr($ip); 

if ($resolved != $ip) { 
	$footer ="text" ;
} else { 
	$footer ="othertext" ;
} 

$message = $_POST ['message']; 
$message = "$message \n\n ------------ \n $footer";
if (mail ('myemail@host.com',$subject ,$message ,"From: $from \r\n Reply-To: $from \r\n ")) { 
	echo 'success' ;
} else { 
	echo 'failure' ;
} 
} else {
echo'
<form method="post" action="'.$_REQUEST['PHP_SELF'].'">
<input type="hidden" name="skin" value="'.$s.'" />  

<p>&nbsp;&nbsp;&nbsp;&nbsp;Please be aware that your 
IP address (<span class="highlighted">'.$ip.'</span>) will be sent along with the messag.......

the output is the following:

$printme = ?>) will be sent along with the message 
to prevent against abuse of this mail form......

which is kinda weird ... what a strange place to start :/

HalfaBee

You need to put the ?> in quotes.

$to_eval = "\$printme = \"?>$content<?php\"";

I hate evals().
