unloading php extensions : reverse dl()

To you gurus out there, is there any hidden gem in PHP that could unload a specific extension at runtime ?

Solution

  • No, that's not possible and most likely never will:

    extension unloading on a per-request basis simply isn't feasible from a performance point of view. And you obviously can't unload and leave it unloaded for the next request because that next request may be for a page that expects the extension to be there.

    However, using dl() is discouraged anyway - and in recent versions it is only available in the CLI version.
