    Here's an updated version of the function:

    <?php
    if (!function_exists('json_last_error_msg')) {
    function     json_last_error_msg() {
    static     $ERRORS = array(
    JSON_ERROR_NONE => 'No error',
    JSON_ERROR_DEPTH => 'Maximum stack depth exceeded',
    JSON_ERROR_STATE_MISMATCH => 'State mismatch (invalid or malformed JSON)',
    JSON_ERROR_CTRL_CHAR => 'Control character error, possibly incorrectly encoded',
    JSON_ERROR_SYNTAX => 'Syntax error',
    JSON_ERROR_UTF8 => 'Malformed UTF-8 characters, possibly incorrectly encoded'
    );

    $error = json_last_error();
    return isset(    $ERRORS[$error]) ? $ERRORS[$error] : 'Unknown error';
    }
    }
    ?>
