This PR removes the closing `?>` PHP tag from generated files. [PSR-2](https://www.php-fig.org/psr/psr-2/) states:
> The closing `?>` tag MUST be omitted from files containing only PHP.
A problem might occur if files with any character after the closing tag are used with `include` or `require`. It might trigger an output and disallow HTTP header manipulation. See the popular [_headers already sent_](https://stackoverflow.com/a/8028987/1847340) debate on SO.
Finally removed support for %pragma(php4) which was deprecated back in
2008. The replacement is %pragma(php), which has been supported since
at least 2005.
PHP5 is no longer actively supported by the PHP developers and security
support for it ends completely at the end of 2018, so it doesn't make
sense to include support for it in the upcoming SWIG 4.0.0 release.
See #701.
- Fixes generation of director method declarations containing C++11 ref-qualifiers.
- Fixes generation of director method declarations returning more complex types such
as const ref pointers.
- Rewrite Swig_method_call to use more up to date code in the core.
The directorin typemaps will now generate a temporary variable
(specified after the type), such as:
%typemap(directorin) MyType (MyType *temp) { ... use temp ... }
The shared_ptr director typemaps have been fixed for use in functions
that take more than one parameter.
MSHUTDOWN, RINIT, RSHUTDOWN and MINFO are often empty, so check and
omit them if this is the case, and set the module structure entry to
NULL instead. Reduces code size, number of external functions on the
module, and runtime overhead a little (RINIT and RSHUTDOWN are called
on every request when used with a webserver).
PHP 7.1 no longer supports calling methods with fewer parameters
than declared, so we need to generate __construct() with default
values for all but the first parameter.
Previously we emitted a separate one for every wrapped function,
but typically many functions have the same number of parameters
and combinations of parameters passed by reference or not.
This change significantly reduces both the size of the generated
wrapper, and of the compiled PHP extension module (e.g. by ~6% for
the stripped extension module for Xapian's PHP7 bindings).
This is SWIG's default for every language except PHP, and now is a
good time to make this change so that once we drop PHP5 support, we'll
have the same default everywhere. It's easy to override the default
with -cppext cxx to get the PHP5 behaviour.
PHP5's C extension API has changed substantially so you need to use
-php7 to specify you want PHP7 compatible wrappers.
Fixes https://github.com/swig/swig/issues/571
Previously the return value of call_user_function() was ignored and we
checked an uninitialised value instead. Fixes#627. Based on patch
from Sergey Seroshtan.

CHANGES.current
Use ZEND_FE_END (introduced sometime around 5.2) to obtain the correct
number of arguments for zend_function_entry. Fallback to the original
3 argument initializer if not defined, however, this will not fix the
initializer warning though for some older versions of PHP.
Provide -cppext as a general command line option for setting the
extension used for generated C++ files (previously it was specific
to the PHP backend). Deprecate the equivalent -suffix option
provided by the Ocaml backend, but continue to support that for
now.
