str(MessageInterface $message) X-Ref |
Returns the string representation of an HTTP message. param: MessageInterface $message Message to convert to a string. return: string |
uri_for($uri) X-Ref |
Returns a UriInterface for the given value. This function accepts a string or UriInterface and returns a UriInterface for the given value. If the value is already a UriInterface, it is returned as-is. param: string|UriInterface $uri return: UriInterface |
stream_for($resource = '', array $options = []) X-Ref |
Create a new stream based on the input type. Options is an associative array that can contain the following keys: - metadata: Array of custom metadata. - size: Size of the stream. This method accepts the following `$resource` types: - `Psr\Http\Message\StreamInterface`: Returns the value as-is. - `string`: Creates a stream object that uses the given string as the contents. - `resource`: Creates a stream object that wraps the given PHP stream resource. - `Iterator`: If the provided value implements `Iterator`, then a read-only stream object will be created that wraps the given iterable. Each time the stream is read from, data from the iterator will fill a buffer and will be continuously called until the buffer is equal to the requested read size. Subsequent read calls will first read from the buffer and then call `next` on the underlying iterator until it is exhausted. - `object` with `__toString()`: If the object has the `__toString()` method, the object will be cast to a string and then a stream will be returned that uses the string value. - `NULL`: When `null` is passed, an empty stream object is returned. - `callable` When a callable is passed, a read-only stream object will be created that invokes the given callable. The callable is invoked with the number of suggested bytes to read. The callable can return any number of bytes, but MUST return `false` when there is no more data to return. The stream object that wraps the callable will invoke the callable until the number of requested bytes are available. Any additional bytes will be buffered and used in subsequent reads. param: resource|string|int|float|bool|StreamInterface|callable|\Iterator|null $resource Entity body data param: array $options Additional options return: StreamInterface |
parse_header($header) X-Ref |
Parse an array of header values containing ";" separated data into an array of associative arrays representing the header key value pair data of the header. When a parameter does not contain a value, but just contains a key, this function will inject a key with a '' string value. param: string|array $header Header to parse into components. return: array Returns the parsed header values. |
normalize_header($header) X-Ref |
Converts an array of header values that may contain comma separated headers into an array of headers with no comma separated values. param: string|array $header Header to normalize. return: array Returns the normalized header field values. |
modify_request(RequestInterface $request, array $changes) X-Ref |
Clone and modify a request with the given changes. This method is useful for reducing the number of clones needed to mutate a message. The changes can be one of: - method: (string) Changes the HTTP method. - set_headers: (array) Sets the given headers. - remove_headers: (array) Remove the given headers. - body: (mixed) Sets the given body. - uri: (UriInterface) Set the URI. - query: (string) Set the query string value of the URI. - version: (string) Set the protocol version. param: RequestInterface $request Request to clone and modify. param: array $changes Changes to apply. return: RequestInterface |
rewind_body(MessageInterface $message) X-Ref |
Attempts to rewind a message body and throws an exception on failure. The body of the message will only be rewound if a call to `tell()` returns a value other than `0`. param: MessageInterface $message Message to rewind |
try_fopen($filename, $mode) X-Ref |
Safely opens a PHP stream resource using a filename. When fopen fails, PHP normally raises a warning. This function adds an error handler that checks for errors and throws an exception instead. param: string $filename File to open param: string $mode Mode used to open the file return: resource |
copy_to_string(StreamInterface $stream, $maxLen = -1) X-Ref |
Copy the contents of a stream into a string until the given number of bytes have been read. param: StreamInterface $stream Stream to read param: int $maxLen Maximum number of bytes to read. Pass -1 return: string |
copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1) X-Ref |
Copy the contents of a stream into another stream until the given number of bytes have been read. param: StreamInterface $source Stream to read from param: StreamInterface $dest Stream to write to param: int $maxLen Maximum number of bytes to read. Pass -1 |
hash(StreamInterface $stream, $algo, $rawOutput = false) X-Ref |
Calculate a hash of a stream. This method reads the entire stream to calculate a rolling hash, based on PHP's `hash_init` functions. param: StreamInterface $stream Stream to calculate the hash for param: string $algo Hash algorithm (e.g. md5, crc32, etc) param: bool $rawOutput Whether or not to use raw output return: string Returns the hash of the stream |
readline(StreamInterface $stream, $maxLength = null) X-Ref |
Read a line from the stream up to the maximum allowed buffer length. param: StreamInterface $stream Stream to read from param: int|null $maxLength Maximum buffer length return: string |
parse_request($message) X-Ref |
Parses a request message string into a request object. param: string $message Request message string. return: Request |
parse_response($message) X-Ref |
Parses a response message string into a response object. param: string $message Response message string. return: Response |
parse_query($str, $urlEncoding = true) X-Ref |
Parse a query string into an associative array. If multiple values are found for the same key, the value of that key value pair will become an array. This function does not parse nested PHP style arrays into an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into `['foo[a]' => '1', 'foo[b]' => '2'])`. param: string $str Query string to parse param: int|bool $urlEncoding How the query string is encoded return: array |
build_query(array $params, $encoding = PHP_QUERY_RFC3986) X-Ref |
Build a query string from an array of key value pairs. This function can use the return value of `parse_query()` to build a query string. This function does not modify the provided keys when an array is encountered (like `http_build_query()` would). param: array $params Query string parameters. param: int|false $encoding Set to false to not encode, PHP_QUERY_RFC3986 return: string |
mimetype_from_filename($filename) X-Ref |
Determines the mimetype of a file by looking at its extension. param: string $filename return: string|null |
mimetype_from_extension($extension) X-Ref |
Maps a file extensions to a mimetype. param: $extension string The file extension. return: string|null |
_parse_message($message) X-Ref |
Parses an HTTP message into an associative array. The array contains the "start-line" key containing the start line of the message, "headers" key containing an associative array of header array values, and a "body" key containing the body of the message. param: string $message HTTP request or response to parse. return: array |
_parse_request_uri($path, array $headers) X-Ref |
Constructs a URI for an HTTP request message. param: string $path Path from the start-line param: array $headers Array of headers (each value an array). return: string |
get_message_body_summary(MessageInterface $message, $truncateAt = 120) X-Ref |
Get a short summary of the message body. Will return `null` if the response is not printable. param: MessageInterface $message The message to get the body summary param: int $truncateAt The maximum allowed size of the summary return: string|null |
_caseless_remove($keys, array $data) X-Ref |
Remove the items given by the keys, case insensitively from the data. param: iterable<string> $keys return: array |
