json_encode utf8

Question

I put some Data in my mysql DB that works fine. But when I get the Data with json_encode I get ist back like this:

{"idpostdata":"49","artID":null,"timestamp":"06.11.2012 13:35","lat":"51.496911","lon":"7.4022327","cellID":null,"road":"Wittener Stra\u00dfe","suburb":"Eichlinghofen","city":"Dortmund","postdatacol":null,"state_district":"Regierungsbezirk Arnsberg","state":"North Rhine-Westphalia","country_code":"de"}

you see "road":"Wittener Stra\ße" is not the correct name it must Wittener Straße

My Code:

<?php
$sql = mysql_query("SELECT * FROM postdata");

while ($ds = mysql_fetch_assoc($sql)) 
  $output[]=$ds;
echo "{uTraf:";
  print(json_encode($output));
echo  "}";
mysql_close($dz);
?>

What is wrong?

Answer 1

What is wrong?

Nothing. \\uxxxx is JSON's way of encoding UTF-8 characters.

It will look all right again when you decode the JSON using a proper JSON decoding method.

Answer 2

Nothing wrong it's part of the json_encoding to prevent faulty character conversion:

Look it up : \ß

When you json_decode($string); it should be fixed again

Answer 3

Use addslashes when you save json data to mysql. And when you get data out, it is will be OK.
