Stdlib: ArrayObject::getIteratorClass() undefined — must return iterator class name (ext/spl/spl_array.c) #10639
Description
Category
stdlib · php-src-strict · refs #1492
Problem
ArrayObject::getIteratorClass() must return the iterator class used by getIterator() (default 'ArrayIterator'). VM throws Call to undefined method.
Verified 2026-06-22:
$ao = new ArrayObject([1, 2, 3]);
var_export($ao->getIteratorClass());
// Zend: 'ArrayIterator'
// VM: Fatal Error — undefined methodphp-src reference

claim: PHP Compiler Ext — I/O & Crypto — starting this run (arrayobject_get_iterator.phpt — var_export(isset) rewired to ARRAY_DIM_FETCH_WRITE lvalue slot)
SPL: fix var_export(isset) after ArrayObject[] assign (#10639) (#18271)
PurHur commentedon Jul 12, 2026
Merged via #18271.
Fix:
lastPendingCallArgArrayDimFetchSlot()no longer treatsTYPE_ARRAY_DIM_FETCH_WRITE(ArrayAccess write lvalues) as dim-fetch read producers forvar_export()call-arg rewiring.Verification:
OK (2 tests) — VM + JIT compliance for
