Parameter type errors and some other cases in SWIG-generated wrappers
now throw a PHP exception, which is how PHP's native parameter handling
deals with similar situations.
See #2014, but not closing yet as there may be more cases to convert.
PHP doesn't accept literal NULL for a parameter passed by reference;
passing a variable with a value of NULL is just like passing a
variable with a different value - we get a PHP reference to the
variable, not NULL.
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
backward compatibility, but add preferred forms WARN_PHP_* and use
these ourselves.
Rename Lib/php4 to Lib/php, Source/Modules/php4.cxx to Source/Modules/php.cxx.
Add typemaps for const reference so Examples/test-suite/apply_signed_char.i
works.
