Summary

  • opcache_invalidate()'s description states it "only invalidates in-memory cache and not file cache", which is incorrect.
  • Since file cache support was added in 2015, zend_accel_invalidate() in ext/opcache/ZendAccelerator.c calls zend_file_cache_invalidate() whenever opcache.file_cache is enabled, which deletes the corresponding compiled file from the file cache (zend_file_cache_unlink() in ext/opcache/zend_file_cache.c).
  • Updated the description to describe the actual behavior instead.

Closes #5696

Test plan

  • Validated the XML with configure.php (no local build environment set up here, would appreciate a CI check)

opcache_invalidate() has called zend_file_cache_invalidate() whenever
opcache.file_cache is enabled since file cache support was added in
2015 (ZendAccelerator.c), which deletes the corresponding file cache
entry. Update the description to reflect this instead of stating that
only the in-memory cache is invalidated.

Closes php#5696

function.opcache-invalidate: Is "This function only invalidates in-memory cache and not file cache." still correct (or was it ever)?
