Bug description: PHP_INT_SIZE inconsistent with pack("i"
Description:
------------
PHP pack documentation:
i signed integer (machine dependent size and byte order)
PHP integer documentation:
Integer size can be determined using the constant PHP_INT_SIZE
On some systems, I believe that the word "integer" will refer to objects
of different sizes, such that pack("i", _) could point to an object of size
X bytes and PHP_INT_SIZE return value Y which is inconsistent.
/main/main.c l.1796:
REGISTER_MAIN_LONG_CONSTANT("PHP_INT_SIZE", sizeof(long), CONST_PERSISTENT
| CONST_CS);
/ext/standard/pack.c l.402-403:
php_pack(argv[currentarg++], sizeof(int), int_map, &output[outputpos]);
outputpos += sizeof(int);
Reproduce code:
---------------
file_put_contents("test.bin",pack("I", 2));
var_dump(PHP_INT_SIZE === filesize("test.bin"));
Expected result:
----------------
bool(true)
Actual result:
--------------
bool(false)
