[PHP-DEV] userland macros

[Cristiano Duarte]

Is possible to implement userland macros in a PHP extension or it can 
only be implemented in the core?

I know that macros is a preprocessor task and I think PHP has no 
preprocessor (does it?).

So it's possible to implement a preprocessor ?

An example (or something like that):
<?
#define DEFAULT_VALUE(check_value, default_value) (isset(check_value) ? 
check_value : default_value)

$a = DEFAULT_VALUE($my_array['some_index'], true);
?>
Best regards,

Cristiano Duarte
