Hi, All extensions in php-src are PHP 3.01 Licensed (libs may, of course, have different license) Is there any strong rule about this ? Or is it OK to have a BSD Licensed extension ?

I think we should allow BSD/MIT licenses, as they are compatible with and less restrictive than the PHP license. TBH, the PHP license seems somewhat dubious when applied to extensions, as most of the additional clauses are simply not applicable (extensions do not bundle the Zend Engine and extensions have no control over the PHP group or the PHP name).

What about the Apache 2 license? I'd like to be able to include the ODPI-C library code [1] in PDO_OCI and/or OCI8. It is being used for Python cx_Oracle [2] and Node.js node-oracledb [3]. ODPI-C is under a dual license, one of which is Apache 2.

Mind: The PHP License[1] doesn't talk about the Zend engine, but "PHP Software", "PHP Software" is, since PHP License 3.01 compared to PHP License 3.0 defined as PEAR, PECL and PHP on [2] The "this software includes the ZendEngine" thing in the PHP distribution's license file[3] is not part of the PHP License, but a requirement for the PHP product, which includes the Zend Engine product, which is licensed under the Zend Engine License[4]. According to the most legal interpretations I know (IANAL ... ask two lawyers, get three answers ...) a BSD-licensed extension bundled in PHP would be relicensed under PHP license "automatically" when being distributed as part of the PHP product.

IANAL-too, and haven't talked to one about this - but will one day.

I however think it makes sense to license all bundled extensions as PHP license with copyright PHP Group as this simplifies moving code around (i.e. if a BSD licensed extension contains some nice macro which might be useful to put into main/ this is simpler from a stricter legal pov if it's the same license)

True. Chris [1] https://github.com/oracle/odpi [2] https://github.com/oracle/python-cx_Oracle [3] https://github.com/oracle/node-oracledb/tree/dev-2.0
