Свойство Тип Описание
$URL_BASE
$avgElapsed integer Reset to zero after each call to statusUpdate() Highest value it should ever reach is $this->avgPeriod
$avgPeriod
$buff
$conn
$connectFailuresMax Config type vars - override in subclass if desired
$connectTimeout
$count
$enqueueSpent float Total number of seconds (fractional) spent in the enqueueStatus() calls (i.e. the customized function that handles each received tweet).
$enqueueTimeMS float Simply: enqueueSpent divided by statusCount Note: by default, calculated fresh for past 60 seconds, every 60 seconds.
$fdrPool
$filterChanged State vars
$filterCheckCount integer By default it is called every 5 seconds, so if doing statusUpdates every 60 seconds and then resetting it, this will usually be 12.
$filterCheckMin
$filterCheckSpent float Total number of seconds (fractional) spent in the checkFilterPredicates() calls
$filterCheckTimeMS float Like $enqueueTimeMS but for the checkFilterPredicates() function.
$filterUpdMin
$followIds @see http://dev.twitter.com/pages/streaming_api_methods#count
$format

Открытые методы

Метод Описание
__construct ( string $username, string $password, string $method = Phirehose::METHOD_SAMPLE, string $format = self::FORMAT_JSON, $lang = FALSE ) Create a new Phirehose object attached to the appropriate twitter stream method.
consume ( boolean $reconnect = TRUE ) Connects to the stream API and consumes the stream. Each status update in the stream will cause a call to the handleStatus() method.
enqueueStatus ( string $status ) This is the one and only method that must be implemented additionally. As per the streaming API documentation, statuses should NOT be processed within the same process that is performing collection
getFollow ( ) : array Returns an array of followed Twitter userIds (integers)
getLang ( ) Returns the ISO 639-1 code formatted language string of the current setting. (http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes).
getLastErrorMsg ( ) : string Returns the last error message (TCP or HTTP) that occured with the streaming API or client. State is cleared upon successful reconnect
getLastErrorNo ( ) : string Returns the last error number that occured with the streaming API or client. Numbers correspond to either the fsockopen() error states (in the case of TCP errors) or HTTP error codes from Twitter (in the case of HTTP errors).
getLocations ( ) : array Returns an array of 4 element arrays that denote the monitored location bounding boxes for tweets using the Geotagging API.
getTrack ( ) : array Returns an array of keywords being tracked
heartbeat ( ) : null Reports a periodic heartbeat. Keep execution time minimal.
setCount ( integer $count ) Sets the number of previous statuses to stream before transitioning to the live stream. Applies only to firehose and filter + track methods. This is generally used internally and should not be needed by client applications.
setFollow ( array $userIds ) Returns public statuses from or in reply to a set of users. Mentions ("Hello @user!") and implicit replies ("@user Hello!" created without pressing the reply button) are not matched. It is up to you to find the integer IDs of each twitter user.
setHostPort ( $port ) : void Set host port
setLang ( string $lang ) Restricts tweets to the given language, given by an ISO 639-1 code (http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes).
setLocations ( array $boundingBoxes ) Specifies a set of bounding boxes to track as an array of 4 element lon/lat pairs denoting , . Only tweets that are both created using the Geotagging API and are placed from within a tracked bounding box will be included in the stream. The user's location field is not used to filter tweets. Bounding boxes are logical ORs and must be less than or equal to 1 degree per side. A locations parameter may be combined with track parameters, but note that all terms are logically ORd.
setLocationsByCircle ( $locations ) Convenience method that sets location bounding boxes by an array of lon/lat/radius sets, rather than manually specified bounding boxes. Each array element should contain 3 element subarray containing a latitude, longitude and radius. Radius is specified in kilometers and is approximate (as boxes are square).
setSecureHostPort ( integer $port ) : void Set secure host port
setTrack ( array $trackWords ) Specifies keywords to track. Track keywords are case-insensitive logical ORs. Terms are exact-matched, ignoring punctuation. Phrases, keywords with spaces, are not supported. Queries are subject to Track Limitations.

Защищенные методы

Метод Описание
checkFilterPredicates ( ) Method called as frequently as practical (every 5+ seconds) that is responsible for checking if filter predicates (ie: track words or follow IDs) have changed. If they have, they should be set using the setTrack() and setFollow() methods respectively within the overridden implementation.
connect ( ) Connects to the stream URL using the configured method.
disconnect ( ) Performs forcible disconnect from stream (if connected) and cleanup.
getAuthorizationHeader ( $url, $requestParams )
log ( $message, String $level = 'notice' ) Basic log function that outputs logging to the standard error_log() handler. This should generally be overridden to suit the application environment.
statusUpdate ( ) Called every $this->avgPeriod (default=60) seconds, and this default implementation calculates some rates, logs them, and resets the counters.

Приватные методы

Метод Описание
reconnect ( ) Reconnects as quickly as possible. Should be called whenever a reconnect is required rather that connect/disconnect to preserve streams reconnect state

Описание методов

__construct() публичный Метод

Methods are: METHOD_FIREHOSE, METHOD_RETWEET, METHOD_SAMPLE, METHOD_FILTER, METHOD_LINKS, METHOD_USER, METHOD_SITE. Note: the method might cause the use of a different endpoint URL. Formats are: FORMAT_JSON, FORMAT_XML
См. также: Phirehose::METHOD_SAMPLE
См. также: Phirehose::FORMAT_JSON
public __construct ( string $username, string $password, string $method = Phirehose::METHOD_SAMPLE, string $format = self::FORMAT_JSON, $lang = FALSE )
$username string Any twitter username. When using oAuth, this is the 'oauth_token'.
$password string Any twitter password. When using oAuth this is you oAuth secret.
$method string
$format string

checkFilterPredicates() защищенный Метод

Note that even if predicates are changed every 5 seconds, an actual reconnect will not happen more frequently than every 2 minutes (as per Twitter Streaming API documentation). Note also that this method is called upon every connect attempt, so if your predicates are causing connection errors, they should be checked here and corrected. This should be implemented/overridden in any subclass implementing the FILTER method.
См. также: setTrack()
См. также: setFollow()
См. также: Phirehose::METHOD_FILTER
protected checkFilterPredicates ( )

connect() защищенный Метод

Connects to the stream URL using the configured method.
protected connect ( )

consume() публичный Метод

Note: in normal use this function does not return. If you pass $reconnect as false, it will still not return in normal use: it will only return if the remote side (Twitter) close the socket. (Or the socket dies for some other external reason.)
См. также: handleStatus()
public consume ( boolean $reconnect = TRUE )
$reconnect boolean Reconnects as per recommended

disconnect() защищенный Метод

Performs forcible disconnect from stream (if connected) and cleanup.
protected disconnect ( )

enqueueStatus() абстрактный публичный Метод

This is the one and only method that must be implemented additionally. As per the streaming API documentation, statuses should NOT be processed within the same process that is performing collection
abstract public enqueueStatus ( string $status )
$status string

getAuthorizationHeader() защищенный Метод

protected getAuthorizationHeader ( $url, $requestParams )

getFollow() публичный Метод

Returns an array of followed Twitter userIds (integers)

Returns the ISO 639-1 code formatted language string of the current setting. (http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes).
public getLang ( )

getLastErrorMsg() публичный Метод

Returns the last error message (TCP or HTTP) that occured with the streaming API or client. State is cleared upon successful reconnect
public getLastErrorMsg ( ) : string
Результат string

getLastErrorNo() публичный Метод

См. также: error_log()
protected log ( $message, String $level = 'notice' )
$level String 'error', 'info', 'notice'. Defaults to 'notice', so you should set this parameter on the more important error messages. 'info' is used for problems that the class should be able to recover from automatically. 'error' is for exceptional conditions that may need human intervention. (For instance, emailing them to a system administrator may make sense.)
