Question

With Php when does an included file get included? Is it during a preprocessing stage or is it during script evaluation?

Right now I have several scripts that share the same header and footer code, which do input validation and exception handling. Like this:

/* validate input */ ... /* process/do task */ ... /* handle exceptions */ ... 

So I’d like to do something like this

#include 'verification.php'  /* process/do task */ ...  #include 'exception_handling.php' 

So if include happens as a preprocessing step, I can do the #include ‘exception_handling.php’ but if not, then any exception will kill the script before it has a chance to evaluate the include.

Thanks

PHP.net: include gives a basic example:

vars.php <?php  $color = 'green'; $fruit = 'apple';  ?>  test.php <?php  echo 'A $color $fruit'; // A  include 'vars.php';  echo 'A $color $fruit'; // A green apple  ?> 

so include happens when its executed in code.
