Bug #77623 [Nab]: jsno_encode handle badly backslashes

Edit report at https://bugs.php.net/bug.php?id=77623&edit=1 ID: 77623 User updated by: marco dot biondi at docomodigital dot com Reported by: marco dot biondi at docomodigital dot com Summary: jsno_encode handle badly backslashes Status: Not a bug Type: Bug Package: Unknown/Other Function Operating System: any PHP Version: Irrelevant Assigned To: cmb Block user comment: N Private report: N New Comment: Yes you are true, I tried to oversimplify the sample and the result is confusing. I discovered this problem trying to forward a complex object with a proper unicode literal \u00BF inside a string field. Even in this case the json_encode convert it in \\u00BF breaking the meaning of the initial string Previous Comments: ------------------------------------------------------------------------ [2019-02-15 12:45:46] cmb@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php A single backslash in a JSON string literal would be an error. ------------------------------------------------------------------------ [2019-02-15 10:07:25] marco dot biondi at docomodigital dot com Description: ------------ --- From manual page: https://php.net/function.json-encode --- Just look at the sample code Test script: --------------- <?php $a = "Srting with a slash: \ Just a slash is that I want!"; $b = "Srting with a slash: \\ Just a slash is that I want!"; var_dump($a); var_dump(json_encode($a)); var_dump($b); var_dump(json_encode($b)); Expected result: ---------------- string(51) "Srting with a slash: \ Just a slash is that I want!" string(53) ""Srting with a slash: \ Just a slash is that I want!"" string(51) "Srting with a slash: \ Just a slash is that I want!" string(53) ""Srting with a slash: \ Just a slash is that I want!"" Actual result: -------------- string(51) "Srting with a slash: \ Just a slash is that I want!" string(54) ""Srting with a slash: \\ Just a slash is that I want!"" string(51) "Srting with a slash: \ Just a slash is that I want!" string(54) ""Srting with a slash: \\ Just a slash is that I want!"" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77623&edit=1
