An quick fix could be :

diff --git a/sapi/cli/php_cli.c b/sapi/cli/php_cli.c
index b4288b8..c2413fa 100644
--- a/sapi/cli/php_cli.c
+++ b/sapi/cli/php_cli.c
@@ -964,7 +964,7 @@ static int do_cli(int argc, char **argv) /* {{{ */
 		PG(during_request_startup) = 0;
 		switch (behavior) {
 		case PHP_MODE_STANDARD:
-			if (strcmp(file_handle.filename, "-")) {
+			if (strcmp(file_handle.filename, "-") || interactive) {
 				cli_register_file_handles();
 			}



however, I am trying to figure out a better solution

Description:
------------
In the interactive shell, after executing a function that writes a string to "php://stdout" file, the prompt doesn't appear back, and no input from the keyboard is recognized. 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.
