Prevent opcache from inlining functions with return-value rules on PHP 8.5+

2026-05-09T23:01:43Z

PHP 8.5's opcache optimizer can inline trivial user functions (constant return values), completely eliminating the DO_UCALL opcode. When this happens, zend_execute_ex is never invoked and snuffleupagus's return-value monitoring hooks never fire. Fix this by setting ZEND_ACC_HAS_TYPE_HINTS on monitored functions' op_arrays during compilation (via sp_op_array_handler). This flag is checked by opcache's zend_try_inline_call() and prevents inlining. For 0-arg functions — the only ones eligible for inlining — there are no RECV opcodes, so the runtime impact is zero. To enable sp_op_array_handler when return-value rules are configured, the extension now registers itself as a zend extension and sets ZEND_COMPILE_HANDLE_OP_ARRAY (previously only done for global_strict). The disabled_function_echo_2 test is updated to use separate echo statements and opcache.optimization_level=0, since opcache's echo merging is a compile-time string concatenation that cannot be prevented per-function. This is a bit ugly, but it's the less awful solution to be able to hook return values.

PHP is now optimizing `echo A,B,C` into `echo A B C`, so the test is pointless.

Add a test for Dateinterval::__construct

As it has been privately reported that the rule might not be working, so better safe than sorry. Moreover, we didn't have tests for `__construct`

On uncommon architectures, like s390x, `-2` instead of `-1` might be printed.
