Description:
------------
PHP behaves differently with the code given in a file and in a parameter provided 
with -r
php -r ignores variables, partially recognizes scalar type hinting.

[root@devel data]# php -r "echo 1;"
1[root@devel data]# php -r "$x=3;"

Parse error: syntax error, unexpected '=' in Command line code on line 1

Warning: Wrong parameter count for var_dump() in Command line code on line 1

# php -r "function foo(int $a){}"

Parse error: syntax error, unexpected '(int )' (int) (T_INT_CAST), expecting '(' in Command line code on line 1

Expected result:
----------------
1

Actual result:
--------------
