Using eval?

php4_23

I have a separeat file that stores my html templates in variables.

I link to the page by using include.
Now here is my problem I have variables in the html that need to be evaluated before being printed. So, I am using the eval() fucntion, problem is that I get a bunch of different errors when I use eval();

here is my code
the html is stored in the html variable

eval ("\$str = \"$html\";");
 echo $;

thanks

If your template files are actually html, like this:
 
<a href="page2.html" target="_blank">This is my link!</a></html>

That is a problem, because that is not PHP, you are trying to evaluate HTML as PHP, which is wrong.

Your html template files must be in this format:

$str="<a href=\"page2.html\" target=\"_blank\">This is my link!</a></html>";

No, I have a separate php file that contains a variable called $html.

This variable contains this

$html= "<table><tr><td>$message</td>
</tr></table>";

I then include("html.php");
and attempt to print the $html file. But I want the the $messages to variable to be evaluted before I print it.
echo $html;

Er, you mean html.php looks like
--------8<-------
<?php
$html= "<table><tr><td>$message</td>
</tr></table>";
?>
----------->8------

Then I think

$message = 'This is a message';
include('html.php');
echo $html;

would work.

So what does it do instead?

php4_23

it does not print the variable

You mean it does print

php4_23

yes, it prints that but not

<table><tr><td>this is a message</td>
</tr></table>

php4_23

that is why i thought maybe I had to use eval() to get it to evaluate it first, but I cant get eval() to work

Then it sounds like the include is working properly, and the string is being evaluated as it should, but $message doesn't have the value it's supposed to.

The variable is set. I cant print it by itself.

Ofcourse my code it alot more complex then then examples I wrote, and I am using arrays.

but it still should work
