PHP json_encode: Handling Malformed UTF-8 Characters

When using json_encode($data) to convert data containing Russian characters, you might encounter errors due to malformed UTF-8 characters. One of these errors is "Malformed UTF-8 characters, possibly incorrectly encoded."

Cause:

This error occurs when the data contains non-UTF-8 characters that disrupt the encoding.

Solution:

To resolve this issue, you can use mb_convert_encoding() to convert the data to a valid UTF-8 encoding. Here's the complete code:

<code class="php">$data['name'] = mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');</code>

This code ensures that any non-UTF-8 characters are removed, and the data can be successfully encoded using json_encode(). It's important to note that using utf8_encode() alone may not be sufficient, as it might introduce other issues with the data's integrity.
