json_encode in PHP: Data Growth

Question

PHP

PHP has built-in facilities for converting data to json. Consider an example:

echo json_encode(iconv('cp1251', 'utf-8', 'тест'));

It will return "\ u0442\ u0435\ u0441\ u0442" (spaces so as not to tempt the parser) - this is 26 bytes, not 10 at all, as we would like.

How so?

Answer 1

Emmm. What's the problem gentlemen? Confident in the encoding - go ahead)
php -r 'var_dump(json_encode("test"));'
string(26) ""\u0442\u0435\u0441\u0442""
php -r 'var_dump(json_encode("test", JSON_UNESCAPED_UNICODE));'
string(10) ""test""

Answer 2

It was already in q& about it. What to do? Accept and enable gzip.

Answer 3

Use self-made json:: encode - there is code for 20 lines.
And even feed him cp1251 without an envelope.
Such solutions have only one drawback - they work hundreds of times as built-in solutions.

Answer 4

Such encoding of non-Latin characters is, so to speak, the only reliable way to guarantee the exact representation of such characters, regardless of the encoding used on the web page. But it's a pity, of course, that there is json_encode()no parameter that allows you to disable such encoding if the encoding of the page and JSON data are certainly the same.
