require

Is it possible to set a require to a variable?
Meaning:

[u]a.php[/u]
echo "hey";

[u]b.php[/u]
$a = require('a.php');
echo eval($a);

The problem I'm having is that b.php will echo "hey" even if I don't include the second line. When I do include the second line, it says:
Parse error: syntax error, unexpected $end eval()'d code on line 1

I want to set the evaluated a.php to a variable, and then change the value of the variable. So I'm altering what was already included. Make sense? I hope so.

Anything you include or require with <?php ?> tags is executed as PHP at run-time.

No you cannot assign a require call to a var but any var declared in the required file WILL become available to the file that included it.

For example this will work:

a.php
<?php
$a = 'lol';
?>

including file
<?php
include('a.php');
echo $a; // Produces 'lol'
?>

Can I use str_replace on something that is required?
How about if I use fopen or something like that and set that to a variable?

Only files included or required will be parsed as PHP, not fopen or file_get_contents and as I said before, you cannot perform any operation on the include statement, but you can do whatever the hell you want with the stuff that is returned from the included file
