Bug #74489 [NEW]: readline() immediately returns false in interactive console mode

From: webmaster_20170422 at cubiclesoft dot com Operating system: Windows PHP version: 7.1.4 Package: Readline related Bug Type: Bug Bug description:readline() immediately returns false in interactive console mode Description: ------------ As of PHP 7.1, the readline extension is compiled into PHP for Windows. Unfortunately, calling readline() with no parameters immediately returns false. No PHP notices, warnings, or errors are emitted. I'm using Windows 10, PHP 7.1.4 (from windows.php.net), and a plain ol' Command Prompt (not elevated). 'php -i' shows: readline Readline Support => enabled Readline library => WinEditLine Looking at the source code, it looks like WinEditLine expects a non-null value to be passed into readline(). Passing an empty string appears to work (readline("")) but the PHP documentation says the parameter is optional. Test script: --------------- <?php var_dump(readline()); ?> Expected result: ---------------- Wait for user input and dump the string when the user presses Enter. Actual result: -------------- readline() with no parameters immediately returns a value of false. -- Edit bug report at https://bugs.php.net/bug.php?id=74489&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74489&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74489&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74489&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74489&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74489&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74489&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74489&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74489&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74489&r=support Expected behavior: https://bugs.php.net/fix.php?id=74489&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74489&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74489&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74489&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74489&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74489&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74489&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74489&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74489&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74489&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74489&r=mysqlcfg
