Advanced usage
In order to create portable code, it's best to assume all the
native functions already exist. Littering a script with
calls to PHP_Compat can become messy,
and increase the work required to port the code.
To solve this there are a number of approaches. The first would
be adding the load statements to a file which is included at the
top of every document. The second, and preferred method is to make
use of php_auto_append php.ini
value. This can be set in a .htaccess file,
and no modifications to the actual code are required.
If phpcompat.php was the name of the file, an
example entry in a .htaccess could be
php_value php_auto_append phpcompat.php.
The phpcompat.php file would make use of either the
loadVersion or loadFunction/loadConstant methods discussed in the next
page.
