FAQ
Hey Georg,

Thanks for committing the draft. I went through and made some notes
on the implementation.

1. Please use ZEND_STR_TYPE instead of UG(unicode)?IS_UNICODE:IS_STRING

2. This type of thing:

+ if (UG(unicode)) {
+ UChar *ustr = USTR_MAKE("mysqli_driver");
+ is_driver = u_strcmp(obj->zo.ce->name.u, ustr);
+ USTR_FREE(ustr);
+ } else {
+ is_driver = strcmp(obj->zo.ce->name.s, "mysqli_driver");
+ }

can be simplified to:

if (ZEND_U_EQUAL(obj->zo.ce->name.s, "mysqli_driver")) { ... }

3. This also:

+ php_error_docref(NULL TSRMLS_CC, E_WARNING, "Couldn't
fetch %R", UG(unicode)?IS_UNICODE:IS_STRING, obj->zo.ce->name );

cna be simplified to:

php_error_docref(NULL TSRMLS_CC, E_WARNING, "Couldn't
fetch %v", obj->zo.ce->name );

4. We have a macro for this:

+ if (UG(unicode)) {
+ UChar *ustr;
+ int ulen;
+
+ zend_string_to_unicode(MYSQLI_CONV_UTF8, &ustr,
&ulen, row[i], field_len[i]);
+ ZVAL_UNICODEL(res, ustr, ulen, 0);
+ } else {
+ ZVAL_STRINGL(res, row[i], field_len[i], 1);
+ }

Just do:

ZVAL_UTF8_STRINGL(res, row[i], field_len[i], ZSTR_DUPLICATE);

5. Your comment:

+ /* maybe a bug in add_u_assoc_zval_ex: string is
truncated when specifying ulen only */
+ add_u_assoc_zval_ex(return_value, IS_UNICODE, ZSTR
(ustr), ulen + 1, res);

is not valid. You always have to specify the length of the full key,
including the NULL byte.

6. Instead of doing this:

+ MYSQLI_CONVERT_PARAM_STRING(statement, MYSQLI_CONV_UTF8);

You can use 's&' specifier and pass the converter, as in:

if (zend_parse_parameters(2 TSRMLS_CC, "Os", &mysql_link,
mysqli_link_class_entry, &str, &str_len, UG(utf8_conv))==FAILURE)

7. This is unnecessary:

+ MYSQLI_RETURN_CONV_STRINGL(MYSQLI_CONV_UTF8, csname, strlen
(csname), 1);

Just use RETURN_UTF8_STRINGL() macro.

8. Don't forget there's also convert_to_string_with_converter[_ex]()
and convert_to_unicode_with_converter[_ex] macros. They're useful.

I didn't go further, because I think we need to fix these first..
