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 this bug report at https://bugs.php.net/bug.php?id=74489&edit=1
