Bug #67693 [NEW]: incorrect push to the empty array

From: dvlasov at parallels dot com Operating system: ubuntu 14.04 (32 bit) PHP version: 5.5.15 Package: Arrays related Bug Type: Bug Bug description:incorrect push to the empty array Description: ------------ When the initial one element array, starting with -1 index, is poped, and afterwards two values are pushed into the obtained empty array, the second value index is becoming 2147483647, which is obviously an error. All other starting indexes (-2, 0, 1, 2,...) do not affect array in this way. Also, when starting index is > 0, the index of the first element, pushed into the empty array is kept from the previous key-value pair. Such behaviour may be also considered erroneous. Test script: --------------- <?php $b=array(-1=>0); $c=array_pop($b); assert($c == 0); assert(array_push($b, 0), 1); assert(array_push($b, 0), 2); var_dump($b); assert(array_push($b, 0), 3); ?> Expected result: ---------------- array(2) { [0]=> int(0) [1]=> int(0) } Actual result: -------------- array(2) { [-1]=> int(0) [2147483647]=> int(0) } PHP Warning: array_push(): Cannot add element to the array as the next element is already occupied in /home/dmitri/workspace/cell/temp/array_push_pop_bug.php on line 8 -- Edit bug report at https://bugs.php.net/bug.php?id=67693&edit=1 --
