Edit report at https://bugs.php.net/bug.php?id=75826&edit=1 ID: 75826 Comment by: spam2 at rhsoft dot net Reported by: leon dot valkenborg at blackpepper dot co dot nz Summary: Unintended array key integer to string conversion after unsetting in foreach Status: Open Type: Bug Package: JSON related Operating System: Ubuntu PHP Version: 7.2.1 Block user comment: N Private report: N New Comment: the bug is more that it don't behave that way before the unset because there is nothing like arrays without kyes in PHP php > $x = ['a', 'b', 'c']; php > print_r($x); Array ( [0] => a [1] => b [2] => c ) Previous Comments: ------------------------------------------------------------------------ [2018-01-16 22:06:28] leon dot valkenborg at blackpepper dot co dot nz Description: ------------ json_encode will parse the PHP array as if it has string keys when a numerical key is unset. var_dump() shows expected results. So i assume this issue is wit json_encode(). Test script: --------------- <? $array = array('a','b','c'); unset($array[0]); echo json_encode($array); ?> Expected result: ---------------- ["b","c"] Actual result: -------------- {"1":"b","2":"c"} ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75826&edit=1
