What potential server configurations or settings could lead to decoding errors of JSON strings in PHP applications?

Potential server configurations or settings that could lead to decoding errors of JSON strings in PHP applications include incorrect character encoding settings, PHP configuration settings such as `magic_quotes_gpc` being enabled, or server-side compression being applied to JSON responses. To solve this issue, ensure that the server's character encoding settings are correctly configured, disable `magic_quotes_gpc` in the PHP configuration, and disable server-side compression for JSON responses. 

// Disable magic quotes GPC
if (get_magic_quotes_gpc()) {
    function stripslashes_deep($value) {
        $value = is_array($value) ?
                    array_map('stripslashes_deep', $value) :
                    stripslashes($value);

        return $value;
    }

    $_POST = array_map('stripslashes_deep', $_POST);
    $_GET = array_map('stripslashes_deep', $_GET);
    $_COOKIE = array_map('stripslashes_deep', $_COOKIE);
    $_REQUEST = array_map('stripslashes_deep', $_REQUEST);
}

// Set correct character encoding
header('Content-Type: application/json; charset=utf-8');

// Disable server-side compression for JSON responses
ini_set('zlib.output_compression', 'Off');
