Doc #77172 [Opn->Ver]: convert error on receiving variables from external sources

Edit report at https://bugs.php.net/bug.php?id=77172&edit=1 ID: 77172 Updated by: cmb@php.net Reported by: zhoumengkang@php.net Summary: convert error on receiving variables from external sources -Status: Open +Status: Verified Type: Documentation Problem Package: Documentation problem Operating System: Linux PHP Version: master-Git-2018-11-18 (Git) -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: I think that an external variable foo[]boo should not be treated as array at all, but be registered verbatim. However, this would likely be a rather severe BC break, so we should document it for now. For PHP 8 we may be able to implement feature request #34882 (and also to cater to cases like reported in this ticket). Previous Comments: ------------------------------------------------------------------------ [2018-11-18 04:43:18] zhoumengkang@php.net Description: ------------ when php receivie the data from external sources, a variables named foo[]boo will be saved into $_POST['foo'][]; doc has noted dots and spaces in variable names are converted to underscores. @see http://php.net/manual/en/language.variables.external.php but there no info tell developers variables can't be named foo[]boo, otherwise the variable foo[]boo should be remove ? Test script: --------------- <form method="post"> <input type="text" name="id[]" value="1"> <input type="text" name="id[]_text" value="a"> <input type="submit"> </form> Expected result: ---------------- array ( 'id' => array ( 0 => '1', ), ) Actual result: -------------- array ( 'id' => array ( 0 => '1', 1 => 'a', ), ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77172&edit=1
