When I use json_encode to encode my multi lingual strings , It also changes special characters.What should I do to keep them same .
For example
<?
echo json_encode(array('şüğçö'));
It returns something like ["\u015f\u00fc\u011f\u00e7\u00f6"]
But I want ["şüğçö"]
try it:
<?
echo json_encode(array('şüğçö'), JSON_UNESCAPED_UNICODE);
In JSON any character in strings may be represented by a Unicode escape sequence. Thus "\u015f\u00fc\u011f\u00e7\u00f6" is semantically equal to "şüğçö".
Although those character can also be used plain, json_encode probably prefers the Unicode escape sequences to avoid character encoding issues.
PHP 5.4 adds the option JSON_UNESCAPED_UNICODE, which does what you want. Note that json_encode always outputs UTF-8.
First, use json_encode() to encode the string and save it in a variable.
Then simply use preg_replace() to replace all \uxxxx with unicode again.
json_encode() does not provide any options for choosing the charset the encoding is in in versions prior to 5.4.
<?php
print_r(json_decode(json_encode(array('şüğçö'))));
/*
Array
(
[0] => şüğçö
)
*/
So do you really need to keep these characters unescaped in the JSON?
\u00e7 characters just fine.Json_encode charset solution for PHP 5.3.3
As JSON_UNESCAPED_UNICODE is not working in PHP 5.3.3 so we have used this method and it is working.
$data = array(
'text' => 'Päiväkampanjat'
);
$json_encode = json_encode($data);
var_dump($json_encode); // text: "P\u00e4iv\u00e4kampanjat"
$unescaped_data = preg_replace_callback('/\\\\u(\w{4})/', function ($matches) {
return html_entity_decode('&#x' . $matches[1] . ';', ENT_COMPAT, 'UTF-8');
}, $json_encode);
var_dump($unescaped); // text is unescaped -> Päiväkampanjat
