From: treboralmasy1 at gmail dot com Operating system: PHP version: 5.6.10 Package: *General Issues Bug Type: Bug Bug description:$_POST data being automatically filtered. Description: ------------ When a form is submitted with an empty value $_POST does not add an empty key. Instead it automatically filters it.

Ie: when no code is entered: file_get_contents('php://input'): username= $_POST: array() when username IS entered: file_get_contents('php://input'): username=test $_POST: array( username=>test) Test script: --------------- <form action="" method="POST"> <input type="text" name="username" /> <input type="submit" value="click"> </form> -- Edit bug report at https://bugs.php.net/bug.php?id=70028&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70028&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70028&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70028&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70028&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70028&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70028&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70028&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70028&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70028&r=support Expected behavior: https://bugs.php.net/fix.php?id=70028&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70028&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70028&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70028&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70028&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70028&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70028&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70028&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70028&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70028&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70028&r=mysqlcfg
