Regarding than older versions of PHP such as 5.3 in the interactive shell mode; 
When a fatal error occurs, this shell exits with 255 code.

Actually in 5.5.7, when a fatal error occurs, the shell continues executing code.

So, when a possible fatal error is suppressed, the shell will no alert again to other kind of errors

Test script:
Example php 5.3 (shell exits with 255):
httpd@dev:~$ php -a; echo exitstatus: $?
Interactive shell
php > @undefined();
exitstatus: 255

Example php 5.5.7 (shell continues):
Interactive shell
httpd@dev55:~$ php -a
php > $var = 3;
php > undefined();
PHP Fatal error:  Call to undefined function undefined() in php shell code on line 1
Fatal error: Call to undefined function undefined() in php shell code on line 1
php > echo $var . "\n";

Example php 5.5.7 (shell continues so weird):
php > $var = 3;
php > @undefined();
php > echo $var . "\n";
php > notdefined();
php > really_not_defined();
php > @really_not_defined();
php > []+$1 ==== class;
php >

Expected result:
Alert on next errors

Actual result:
Not alerting next errors (fatal, warnings, syntax, etc)

I cannot reproduce this with PHP-7.1.  Can anybody else still
reproduce it with any actively supported PHP version[1]?
