Question

我正在尝试从表单中推导出一个文件，显示西里尔文时出现问题PHP (7.1)<?php    header("Content-type: application/json; charset=utf-8");    file_put_contents('export.json', json_encode($_REQUEST) );?>输出 You_name 字段是用字符写的。{"Entry_ID":"71","You_name":"\u041a\u043e\u0437\u043b\u0430\u043d\u0431\u0435\u043a \u0410\u043c\u0438\u0440 \u041f\u043e\u043c\u0438\u0434\u043e\u0440\u043e\u0432\u0438\u0447","You_phone":"7 [phone]","You_date":"19\/06\/2019"}

Answer 1

json_encode( $text, JSON_UNESCAPED_UNICODE );

例子：

/tmp $ cat test.php

<?php

echo json_encode(['key'=>'ыфва']), PHP_EOL;

echo json_encode(['key'=>'ыфва'], JSON_UNESCAPED_UNICODE), PHP_EOL;

/tmp $ php test.php

{"key":"\u044b\u0444\u0432\u0430"}

{"key":"ыфва"}

/tmp $ php --version

Answer 2

您应该使用 $_POST 来获取表单数据，如下所示

  header("Content-type: application/json; charset=utf-8");

  file_put_contents('export.json', json_encode($_POST) );

Answer 3

试试这个（来源）：

header("Content-type: application/json; charset=utf-8")

$convert = file_put_contents('export.json', json_encode($_REQUEST));

$convert = iconv('CP1251', 'UTF-8', $convert);
