Hi,
Is there a way to get the version of the PHP binary that loaded an
extension from within the extension? I don't mean the PHP version the
extension was compiled with (PHP_VERSION), I mean the version of the
PHP binary itself?
Can I call the phpversion function from within an extension?
Similarly is there a way to get the zend API version of the PHP binary
(not the version the extension was compiled with)?
[EMAIL PROTECTED]:~/cvs/php-5.2$ grep -E 'version.*\);' Zend/*.h
Zend/zend_API.h:ZEND_API char *zend_get_module_version(char *module_name);
Zend/zend_extensions.h:void zend_append_version_info(zend_extension
*extension);
Zend/zend.h:ZEND_API char *get_zend_version(void);
You could query ext/standard for the PHP version, everything else should be
self explanatory.
Yes, that does give me the PHP version. Thanks.
The get_zend_version function returns a string like 'Zend Engine v1.3.0,
Copyright (c) 1998-2004 Zend Technologies\n'. It would be nice to be
able to get the ZEND_MODULE_API_NO (e.g. 20060613) the standard module
was compiled under.
I'm still confused about how many versions of extensions I need to provide
with my product. Currently I just compile it against late versions of 4,
5.0, 5.1 and 5.2 and hope for the best. But looking at ZEND_MODULE_API_NO
changes in webcvs shows it changes more frequently than that.
But so far I haven't ran into major problems with ZEND_MODULE_API_NO
so maybe I'm just being paranoid. From looking at zend.c it looks like
it will print diagnostic info if some tries to load an incompatible
extension.
