    Variable PLATFORM_PHP_VERSIONConst

    PLATFORM_PHP_VERSION: "8.5.2" = '8.5.2'

    The interpreter version this map reports.

    STALE AT 8.3.0 UNTIL NOW, and the failure was silent in the same direction as the metadata URL above: the shipping binary is 8.5 -- wrangler.jsonc aliases php-binary-85.ts and a deployed site reports 8.5.2 from /php -- so anything requiring >=8.4 was refused as unsatisfiable by a platform that satisfies it. A refusal reads as a considered answer, which is why nothing looked broken.

    The extension entries carry the same version because a bundled extension is part of the interpreter; a constraint on ext-dom is really a constraint on the build that provides it.
