+ * Append a filter callback to the given stream.
+ *
+ * Each stream can have a list of filters attached.
+ * This function appends a filter to the end of this list.
+ *
+ * If the given filter can not be added, it throws an `Exception`.
+ *
+ * The `$stream` can be any valid stream resource, such as:
+ *
+ * ```php
+ * $stream = fopen('demo.txt', 'w+');
+ * ```
+ *
+ * The `$callback` should be a valid callable function which accepts
+ * an individual chunk of data and should return the updated chunk:
+ *
+ * ```php
+ * $filter = Clue\StreamFilter\append($stream, function ($chunk) {
+ *     // will be called each time you read or write a $chunk to/from the stream
+ *     return $chunk;
+ * });
+ * ```
+ *
+ * As such, you can also use native PHP functions or any other `callable`:
+ *
+ * ```php
+ * Clue\StreamFilter\append($stream, 'strtoupper');
+ *
+ * // will write "HELLO" to the underlying stream
+ * fwrite($stream, 'hello');
+ * ```
+ *
+ * If the `$callback` accepts invocation without parameters,
+ * then this signature will be invoked once ending (flushing) the filter:
+ *
+ * ```php
+ * Clue\StreamFilter\append($stream, function ($chunk = null) {
+ *     if ($chunk === null) {
+ *         // will be called once ending the filter
+ *         return 'end';
+ *     }
+ *     // will be called each time you read or write a $chunk to/from the stream
+ *     return $chunk;
+ * });
+ *
+ * fclose($stream);
+ * ```
+ *
+ * > Note: Legacy PHP versions (PHP < 5.4) do not support passing additional data
+ * from the end signal handler if the stream is being closed.
+ *
+ * If your callback throws an `Exception`, then the filter process will be aborted.
+ * In order to play nice with PHP's stream handling,
+ * the `Exception` will be transformed to a PHP warning instead:
+ *
+ * ```php
+ * Clue\StreamFilter\append($stream, function ($chunk) {
+ *     throw new \RuntimeException('Unexpected chunk');
+ * });
+ *
+ * // raises an E_USER_WARNING with "Error invoking filter: Unexpected chunk"
+ * fwrite($stream, 'hello');
+ * ```
+ *
+ * The optional `$read_write` parameter can be used to only invoke the `$callback`
+ * when either writing to the stream or only when reading from the stream:
+ *
+ * ```php
+ * Clue\StreamFilter\append($stream, function ($chunk) {
+ *     // will be called each time you write to the stream
+ *     return $chunk;
+ * }, STREAM_FILTER_WRITE);
+ *
+ * Clue\StreamFilter\append($stream, function ($chunk) {
+ *     // will be called each time you read from the stream
+ *     return $chunk;
+ * }, STREAM_FILTER_READ);
+ * ```
+ *
+ * This function returns a filter resource which can be passed to [`remove()`](#remove).
+ *
+ * > Note that once a filter has been added to stream, the stream can no longer be passed to
+ * > [`stream_select()`](https://www.php.net/manual/en/function.stream-select.php)
+ * > (and family).
+ * >
+ * > > Warning: stream_select(): cannot cast a filtered stream on this system in {file} on line {line}
+ * >
+ * > This is due to limitations of PHP's stream filter support, as it can no longer reliably
+ * > tell when the underlying stream resource is actually ready.

+/**
+ * Create a filter function which uses the given built-in `$filter`.
+ *
+ * PHP comes with a useful set of [built-in filters](https://www.php.net/manual/en/filters.php).
+ * Using `fun()` makes accessing these as easy as passing an input string to filter
+ * and getting the filtered output string.
+ *
+ * ```php
+ * $fun = Clue\StreamFilter\fun('string.rot13');
+ *
+ * assert('grfg' === $fun('test'));
+ * assert('test' === $fun($fun('test'));
+ * ```
+ *
+ * Please note that not all filter functions may be available depending
+ * on installed PHP extensions and the PHP version in use.
+ * In particular, [HHVM](https://hhvm.com/) may not offer the same filter functions
+ * or parameters as Zend PHP.
+ * Accessing an unknown filter function will result in a `RuntimeException`:
+ *
+ * ```php
+ * Clue\StreamFilter\fun('unknown'); // throws RuntimeException
+ * ```
+ *
+ * Some filters may accept or require additional filter parameters – most
+ * filters do not require filter parameters.
+ * If given, the optional `$parameters` argument will be passed to the
+ * underlying filter handler as-is.
+ * In particular, note how *not passing* this parameter at all differs from
+ * explicitly passing a `null` value (which many filters do not accept).
+ * Please refer to the individual filter definition for more details.
+ * For example, the `string.strip_tags` filter can be invoked like this:
+ *
+ * ```php
+ * $fun = Clue\StreamFilter\fun('string.strip_tags', '<a><b>');
+ *
+ * $ret = $fun('<b>h<br>i</b>');
+ * assert('<b>hi</b>' === $ret);
+ * ```
+ *
+ * Under the hood, this function allocates a temporary memory stream, so it's
+ * recommended to clean up the filter function after use.
+ * Also, some filter functions (in particular the
+ * [zlib compression filters](https://www.php.net/manual/en/filters.compression.php))
+ * may use internal buffers and may emit a final data chunk on close.
+ * The filter function can be closed by invoking without any arguments:
+ *
+ * ```php
+ * $fun = Clue\StreamFilter\fun('zlib.deflate');
+ *
+ * $ret = $fun('hello') . $fun('world') . $fun();
+ * assert('helloworld' === gzinflate($ret));
+ * ```
+ *
+ * The filter function must not be used anymore after it has been closed.
+ * Doing so will result in a `RuntimeException`:
+ *
+ * ```php
+ * $fun = Clue\StreamFilter\fun('string.rot13');
+ * $fun();
+ *
+ * $fun('test'); // throws RuntimeException
+ * ```
+ *
+ * > Note: If you're using the zlib compression filters, then you should be wary
+ * about engine inconsistencies between different PHP versions and HHVM.
+ * These inconsistencies exist in the underlying PHP engines and there's little we
+ * can do about this in this library.
+ * [Our test suite](tests/) contains several test cases that exhibit these issues.
+ * If you feel some test case is missing or outdated, we're happy to accept PRs! :)
