Bug #76852 [NEW]: IteratorIterator doesn't initialize without being rewound

From: morozov at tut dot by Operating system: Linux PHP version: 7.2.9 Package: SPL related Bug Type: Bug Bug description:IteratorIterator doesn't initialize without being rewound Description: ------------ Right after construction, the state of IteratorIterator doesn't reflect the state of the underlying iterator. Despite the fact that the underlying iterator is valid and has non-empty values of key and value, the wrapper is invalid and hass NULL values of key and value. Test script: --------------- $it = new ArrayIterator([1, 2, 3]); var_dump($it->valid()); var_dump($it->key()); var_dump($it->current()); $it = new IteratorIterator($it); var_dump($it->valid()); var_dump($it->key()); var_dump($it->current()); Expected result: ---------------- bool(true) int(0) int(1) bool(true) int(0) int(1) Actual result: -------------- bool(true) int(0) int(1) bool(false) NULL NULL -- Edit bug report at https://bugs.php.net/bug.php?id=76852&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76852&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76852&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76852&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76852&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76852&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76852&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76852&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76852&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76852&r=support Expected behavior: https://bugs.php.net/fix.php?id=76852&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76852&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76852&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76852&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76852&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76852&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76852&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76852&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76852&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76852&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76852&r=mysqlcfg
