encoding - How can I use swedish letters with json_encode() in PHP? -

i have array this, json encode:

    $regulararray = array(               array( "label" => "hello world", "value" => 1 ),         array( "label" => "hej världen", "value" => 2 )     );      $jsonarray = json_encode( $regulararray ); 

("hej världen" means hello world in swedish) when print $jsonarray this:

[{"label":"hello world","value":1},{"label":null,"value":2}] 

why label null second item in array? know has word "världen" since contains non-standard letter. how can around this?

json_encode function works utf-8 encoded data. may change input array data utf-8.

encode input array data using utf8_encode , decode whenever need data using utf8_decode

<?php    $regulararray = array(               array( "label" => "hello world", "value" => 1 ),         array( "label" => "hej världen", "value" => 2 )     );     $regulararray[1]['label'] = utf8_encode( $regulararray[1]['label']);     echo $jsonarray = json_encode( $regulararray );     $data = json_decode($jsonarray, true);     $data[1]['label'] = utf8_decode($data[1]['label']);     print_r($data);  ?> 

output:-

[{"label":"hello world","value":1},{"label":"hej v\u00c3\u00a4rlden","value":2}] array (     [0] => array         (             [label] => hello world             [value] => 1         )      [1] => array         (             [label] => hej världen             [value] => 2         )  )
