The only thing left to do is terminating the process (Ctrl+C) and starting the shell again. Test script: --------------- // Start the interactive shell // $ php -a file_put_contents("php://stdout", "Hello, World!"); // The string is correctly printed, but no prompt is available any more, // and no keyboard input is recognized. Expected result: ---------------- After printing the expected string (which happens correctly) I expect the prompt "php > " to be available again, and to be able to continue working with the shell. Actual result: -------------- The prompt "php > " doesn't appear after printing the string, and the shell is frozen, not accepting any input from the keyboard. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71229&edit=1
