[php] Any way to return PHP `json_encode` with encode UTF-8 and not Unicode?

Any way to return PHP json_encode with encode UTF-8 and not Unicode?

$arr=array('a'=>'á');
echo json_encode($arr);

mb_internal_encoding('UTF-8');and $arr=array_map('utf8_encode',$arr); does not fix it.

Result: {"a":"\u00e1"}

Expected result: {"a":"á"}

This function found here, works fine for me

function jsonRemoveUnicodeSequences($struct) {
   return preg_replace("/\\\\u([a-f0-9]{4})/e", "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode($struct));
}

Use JSON_UNESCAPED_UNICODE inside json_encode() if your php version >=5.4.

I resolved my problem doing this:

• The .php file is encoded to ANSI. In this file is the function to create the .json file.
• I use json_encode($array, JSON_UNESCAPED_UNICODE) to encode the data;

The result is a .json file encoded to ANSI as UTF-8.

just use this,

utf8_encode($string);

you've to replace your $arr with $string.

I think it will work...try this.
