[$] A PHP license change is imminent

PHP's licensing has been a source of confusion for some time. The project is,
currently, using two licenses that cover different parts of the code base: for code
in the Zend directory. Much has changed
since the project settled on those licenses in 2006, and the need for custom
licensing seems to have passed. An effort to simplify PHP's licensing, led by
Ben Ramsey, is underway; if successful, the existing licenses will be deprecated
and replaced by the through April 4, 2026.
