PHP json_encode json_decode UTF-8

How can I save a json-encoded string with international characters to the databse and then parse the decoded string in the browser?

$string = "très agréable";
// to the database
$j_encoded = json_encode(utf8_encode($string));
// get from Database
$j_decoded = json_decode($j_encoded);

<?= $j_decoded ?>

This is an encoding issue. It looks like at some point, the data gets represented as ISO-8859-1.

Every part of your process needs to be UTF-8 encoded.

  • The database connection

  • The database tables

  • Your PHP file (if you are using special characters inside that file as shown in your example above)

  • The content-type headers that you output
