`SWIG_ErrorCode()`, `SWIG_ErrorMsg()`, `SWIG_FAIL()` and `goto thrown;`
are no longer supported (these are really all internal implementation
details and none are documented aside from brief mentions in CHANGES
for the first three). I wasn't able to find any uses at least in FOSS
code via code search tools.
If you are using these:
Use `SWIG_PHP_Error(code,msg);` instead of `SWIG_ErrorCode(code);
SWIG_ErrorMsg(msg);` (which will throw a PHP exception in SWIG >= 4.1
and do the same as the individual calls in older SWIG).
`SWIG_FAIL();` and `goto thrown;` can typically be replaced with
`SWIG_fail;`. This will probably also work with older SWIG, but
please test with your wrappers if this is important to you.
Fixes#2014
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.
Most pre-defined interfaces are accessible via zend_class_entry*
variables declared in the PHP C API - we can use these to add
an interface at MINIT time (rather than having to wait until RINIT to
look up by name) by having a mapping from PHP interface name to them.
This will also be a little faster than looking up by name.
Closes#2013
PHPCN(x) does a string compare of x with the lower-cased class name,
so x needs to be in lowercase or else the entry has no effect. The
entries for TRUE, FALSE and NULL weren't working as a result.
Add some missing entries, remove some long obsolete entries (from
the "ming" extension for generating SWF files, which was split
out from PHP core in 2008), and entry for "static" as a reserved class
name (`static::` is used for late static bindings, but attempting to
name a PHP class `static` fails because `static` is a keyword and we
also list it as such).
Eliminate redundant and unused includes.
Only include the minimum headers needed before the PHP_MAJOR_VERSION
check in case future PHP versions remove some of the headers we
include.
With modern PHP it only works with the CLI version of PHP, so it's
better to direct users to load the extension via "extension=" in
php.ini.
Suggested by ferdynator in #1529.
A PHP exception now gets translated to a C++ exception to skips over C++
code to get back to PHP, avoiding the need to gate every directorout
typemap on EG(exception).
$needNewFlow in an output typemap is now only relevant when wrapping
to a PHP __construct method, and there the return type is known so
factory.i isn't useful.
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.
This isn't really workable since PHP doesn't support intercepting
accesses to global variables (nor to static class properties, so
we can't wrap C/C++ global variables that way either).
The _get() and _set() function wrappers actually work and have
been generated for a very long time.
Mark the parameter as "byref" and write back through the reference
after the call.
Adjust testcase argout to uncomment the part that's meant to test this,
and to remove lingering traces of PHP's old call-time pass-by-reference
(which was completely removed before PHP 7).
Fixes#1457
