+
+## Why?
+
+PHP's stream filtering system is great!
+
+It offers very powerful stream filtering options and comes with a useful set of built-in filters.
+These filters can be used to easily and efficiently perform various transformations on-the-fly, such as:
+
+* read from a gzip'ed input file,
+* transcode from ISO-8859-1 (Latin1) to UTF-8,
+* write to a bzip output file
+* and much more.
+
+But let's face it:
+Its API is [*difficult to work with*](https://www.php.net/manual/en/php-user-filter.filter.php)
+and its documentation is [*subpar*](https://stackoverflow.com/questions/27103269/what-is-a-bucket-brigade).
+This combined means its powerful features are often neglected.
+
+This project aims to make these features more accessible to a broader audience.
+* **Lightweight, SOLID design** -
+  Provides a thin abstraction that is [*just good enough*](https://en.wikipedia.org/wiki/Principle_of_good_enough)
+  and does not get in your way.
+  Custom filters require trivial effort.
+* **Good test coverage** -
+  Comes with an automated tests suite and is regularly tested in the *real world*

+
+## Usage
+
+This lightweight library consists only of a few simple functions.
+All functions reside under the `Clue\StreamFilter` namespace.
+
+The below examples refer to all functions with their fully-qualified names like this:
+
+```php
+Clue\StreamFilter\append(…);
+```
+
+As of PHP 5.6+ you can also import each required function into your code like this:
+
+```php
+use function Clue\StreamFilter\append;
+
+append(…);
+```
+
+Alternatively, you can also use an import statement similar to this:
+
+```php
+use Clue\StreamFilter as Filter;
+
+Filter\append(…);
+```
+
+### append()
+
+The `append(resource<stream> $stream, callable $callback, int $read_write = STREAM_FILTER_ALL): resource<stream filter>` function can be used to
+append a filter callback to the given stream.
+
+Each stream can have a list of filters attached.
+This function appends a filter to the end of this list.
+
+If the given filter can not be added, it throws an `Exception`.
+
+The `$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.
+> As an alternative, consider calling `stream_select()` on the unfiltered stream and
+> then pass the unfiltered data through the [`fun()`](#fun) function.
+
+### prepend()
+
+The `prepend(resource<stream> $stream, callable $callback, int $read_write = STREAM_FILTER_ALL): resource<stream filter>` function can be used to
+prepend a filter callback to the given stream.
+
+Each stream can have a list of filters attached.
+This function prepends a filter to the start of this list.
+
+If the given filter can not be added, it throws an `Exception`.
+
+```php
+$filter = Clue\StreamFilter\prepend($stream, function ($chunk) {
+    // will be called each time you read or write a $chunk to/from the stream
+    return $chunk;
+});
+```
+
+This function returns a filter resource which can be passed to [`remove()`](#remove).
+
+Except for the position in the list of filters, this function behaves exactly
+like the [`append()`](#append) function.
+For more details about its behavior, see also the [`append()`](#append) function.
+
+### fun()
+
+The `fun(string $filter, mixed $parameters = null): callable` function can be used to
+create a filter function which uses the given built-in `$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! :)
+
+### remove()
+
+The `remove(resource<stream filter> $filter): bool` function can be used to
+remove a filter previously added via [`append()`](#append) or [`prepend()`](#prepend).
+
+```php
+$filter = Clue\StreamFilter\append($stream, function () {
+    // …
+});
+Clue\StreamFilter\remove($filter);
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org/).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This project follows [SemVer](https://semver.org/).
+This will install the latest supported version:
+
+```bash
+$ composer require clue/stream-filter:^1.7
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 8+ and
+HHVM.
+It's *highly recommended to use the latest supported PHP version* for this project.
+Older PHP versions may suffer from a number of inconsistencies documented above.
+
+## Tests

+/**
+ * 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! :)

+Symfony Deprecation Contracts
+=============================
+
+A generic function and convention to trigger deprecation notices.
+
+This package provides a single global function named `trigger_deprecation()` that triggers silenced deprecation notices.
+
+By using a custom PHP error handler such as the one provided by the Symfony ErrorHandler component,
+the triggered deprecations can be caught and logged for later discovery, both on dev and prod environments.
+
+The function requires at least 3 arguments:
+ - the name of the Composer package that is triggering the deprecation
+ - the version of the package that introduced the deprecation
+ - the message of the deprecation
+ - more arguments can be provided: they will be inserted in the message using `printf()` formatting
+
+Example:
+```php
+trigger_deprecation('symfony/blockchain', '8.9', 'Using "%s" is deprecated, use "%s" instead.', 'bitcoin', 'fabcoin');
+```
+
+This will generate the following message:
+`Since symfony/blockchain 8.9: Using "bitcoin" is deprecated, use "fabcoin" instead.`
+
+While not recommended, the deprecation notices can be completely ignored by declaring an empty
+`function trigger_deprecation() {}` in your application.
