Test script: --------------- <?php class Test { function run() { $this->arr = array('item'); var_dump(key($this->arr)); // dumps 0 // this unexpectedly advances the internal array pointer foreach ($this->getArr() as $v) {} var_dump(key($this->arr)); // dumps NULL } function getArr() { // is NOT returned by reference return $this->arr; } } $test = new Test; $test->run(); Expected result: ---------------- It dumps "0" in second time too. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62901&edit=1
