If you have code in your database, you don't include() it but eval() it.
Make sure though that the code is error-free (at least no fatal errors):
global $php_errormsg;
$php_errormsg = null;
$result = @eval($code);
$error = $php_errmsg;
This will execute the contents of "$code" as if it were a PHP source file.
You can even use such constructs:
// do some stuff here
?>Hello from outside PHP<br />
<?php
// do some more stuff here
If your code uses "return" to return a value, eval will have this as its
return value (see sample above). If your code doesn't use return, $result
will be null.
If youc code produces a fatal error, @eval will terminate the script (not
only the eval!) without any further message. Omitting the "@" (using
$result = eval($code)) will print the error, notification, or warning to
stdout, as usual. Additionally (in both cases), $php_errormsg will contain
the very last PHP error (thus I read it out immediately).
Works like a charm, half of my apps depend on that...
