PHPXRef 0.7.1 : WordPress Trunk (Updated Daily) : Detail view of SimplePie.php

SimplePie

The SimplePie class contains feed level data and options

To use SimplePie, create the SimplePie object with no parameters. You can
then set configuration options using the provided methods. After setting
them, you must initialise the feed using $feed->init(). At that point the
object's methods and properties will be available to you.

Previously, it was possible to pass in the feed URL along with cache
options directly into the constructor. This has been removed as of 1.3 as
it caused a lot of confusion.

__toString() X-Ref

Used for converting object to a string

__destruct() X-Ref

Remove items that link back to this before destroying this object

force_feed($enable = false) X-Ref

Force the given data/URL to be treated as a feed

This tells SimplePie to ignore the content-type provided by the server.
Be careful when using this option, as it will also disable autodiscovery.

param: bool $enable Force the given data/URL to be treated as a feed

set_feed_url($url) X-Ref

Set the URL of the feed you want to parse

This allows you to enter the URL of the feed you want to parse, or the
website you want to try to use auto-discovery on. This takes priority
over any set raw data.

You can set multiple feeds to mash together by passing an array instead
of a string for the $url. Remember that with each additional feed comes
additional processing and resources.

param: string|array $url This is the URL (or array of URLs) that you want to parse.

set_file(&$file) X-Ref

Set an instance of {@see \SimplePie\File} to use as a feed

param: \SimplePie\File &$file
return: bool True on success, false on failure

set_raw_data($data) X-Ref

Set the raw XML data to parse

Allows you to use a string of RSS/Atom data instead of a remote feed.

If you have a feed available as a string in PHP, you can tell SimplePie
to parse that data string instead of a remote feed. Any set feed URL
takes precedence.

param: string $data RSS or Atom data as a string.

set_timeout($timeout = 10) X-Ref

Set the default timeout for fetching remote feeds

This allows you to change the maximum time the feed's server to respond
and send the feed back.

param: int $timeout The maximum number of seconds to spend waiting to retrieve a feed.

set_curl_options(array $curl_options = []) X-Ref

Set custom curl options

This allows you to change default curl options

param: array $curl_options Curl options to add to default settings

force_fsockopen($enable = false) X-Ref

Force SimplePie to use fsockopen() instead of cURL

param: bool $enable Force fsockopen() to be used

enable_cache($enable = true) X-Ref

Enable/disable caching in SimplePie.

This option allows you to disable caching all-together in SimplePie.
However, disabling the cache can lead to longer load times.

param: bool $enable Enable caching

set_cache(CacheInterface $cache) X-Ref

Set a PSR-16 implementation as cache

param: CacheInterface $psr16cache The PSR-16 cache implementation
return: void

force_cache_fallback($enable = false) X-Ref

SimplePie to continue to fall back to expired cache, if enabled, when
feed is unavailable.

This tells SimplePie to ignore any file errors and fall back to cache
instead. This only works if caching is enabled and cached content
still exists.

param: bool $enable Force use of cache on fail.

set_cache_duration($seconds = 3600) X-Ref

Set the length of time (in seconds) that the contents of a feed will be
cached

param: int $seconds The feed content cache duration

set_autodiscovery_cache_duration($seconds = 604800) X-Ref

Set the length of time (in seconds) that the autodiscovered feed URL will
be cached

param: int $seconds The autodiscovered feed URL cache duration.

set_cache_location($location = './cache') X-Ref

Set the file system location where the cached files should be stored

param: string $location The file system location.

get_cache_filename($url) X-Ref

Return the filename (i.e. hash, without path and without extension) of the file to cache a given URL.

param: string $url The URL of the feed to be cached.
return: string A filename (i.e. hash, without path and without extension).

enable_order_by_date($enable = true) X-Ref

Set whether feed items should be sorted into reverse chronological order

param: bool $enable Sort as reverse chronological order.

set_input_encoding($encoding = false) X-Ref

Set the character encoding used to parse the feed

This overrides the encoding reported by the feed, however it will fall
back to the normal encoding detection if the override fails

param: string $encoding Character encoding

set_autodiscovery_level($level = self::LOCATOR_ALL) X-Ref

Set how much feed autodiscovery to do

param: int $level Feed Autodiscovery Level (level can be a combination of the above constants, see bitwise OR operator)

get_registry() X-Ref

No description

strip_attributes($attribs = '') X-Ref

set_output_encoding($encoding = 'UTF-8') X-Ref

Set the output encoding

Allows you to override SimplePie's output to match that of your webpage.
This is useful for times when your webpages are not being served as
UTF-8. This setting will be obeyed by {@see handle_content_type()}, and
is similar to {@see set_input_encoding()}.

It should be noted, however, that not all character encodings can support
all characters. If your page is being served as ISO-8859-1 and you try
to display a Japanese feed, you'll likely see garbled characters.
Because of this, it is highly recommended to ensure that your webpages
are served as UTF-8.

The number of supported character encodings depends on whether your web
host supports {@link http://php.net/mbstring mbstring},
{@link http://php.net/iconv iconv}, or both. See
{@link http://simplepie.org/wiki/faq/Supported_Character_Encodings} for
more information.

param: string $encoding

set_image_handler($page = false, $qs = 'i') X-Ref

Set the handler to enable the display of cached images.

param: string $page Web-accessible path to the handler_image.php file.
param: string $qs The query string that the value should be passed to.

set_item_limit($limit = 0) X-Ref

Set the limit for items returned per-feed with multifeeds

param: integer $limit The maximum number of items to return.

enable_exceptions($enable = true) X-Ref

Enable throwing exceptions

param: boolean $enable Should we throw exceptions, or use the old-style error property?

init() X-Ref

Initialize the feed object

This is what makes everything happen. Period. This is where all of the
configuration options get processed, feeds are fetched, cached, and
parsed, and all of that other good stuff.

return: boolean True if successful, false otherwise

fetch_data(&$cache) X-Ref

Fetch the data via \SimplePie\File

If the data is already cached, attempt to fetch it from there instead
param: Base|DataCache|false $cache Cache handler, or false to not load from the cache
return: array|true Returns true if the data was loaded from the cache, or an array of HTTP headers and sniffed type

error() X-Ref

Get the error message for the occurred error

return: string|array Error message, or array of messages for multifeeds

status_code() X-Ref

Get the last HTTP status code

return: int Status code

get_raw_data() X-Ref

Get the raw XML

This is the same as the old `$feed->enable_xml_dump(true)`, but returns
the data instead of printing it.

return: string|boolean Raw XML data, false if the cache is used

get_encoding() X-Ref

Get the character encoding used for output

return: string

handle_content_type($mime = 'text/html') X-Ref

Send the content-type header with correct encoding

This method ensures that the SimplePie-enabled page is being served with
the correct {@link http://www.iana.org/assignments/media-types/ mime-type}
and character encoding HTTP headers (character encoding determined by the
{@see set_output_encoding} config option).

This won't work properly if any content or whitespace has already been
sent to the browser, because it relies on PHP's
{@link http://php.net/header header()} function, and these are the
circumstances under which the function works.

Because it's setting these settings for the entire page (as is the nature
of HTTP headers), this should only be used once per page (again, at the
top).

param: string $mime MIME type to serve the page as

get_type() X-Ref

Get the type of the feed

This returns a \SimplePie\SimplePie::TYPE_* constant, which can be tested against
using {@link http://php.net/language.operators.bitwise bitwise operators}

return: int \SimplePie\SimplePie::TYPE_* constant

subscribe_url($permanent = false) X-Ref

Get the URL for the feed

When the 'permanent' mode is enabled, returns the original feed URL,
except in the case of an `HTTP 301 Moved Permanently` status response,
in which case the location of the first redirection is returned.

When the 'permanent' mode is disabled (default),
may or may not be different from the URL passed to {@see set_feed_url()},
depending on whether auto-discovery was used, and whether there were
any redirects along the way.

param: bool $permanent Permanent mode to return only the original URL or the first redirection
return: string|null

get_feed_tags($namespace, $tag) X-Ref

Get data for an feed-level element

This method allows you to get access to ANY element/attribute that is a
sub-element of the opening feed tag.

The return value is an indexed array of elements matching the given
namespace and tag name. Each element has `attribs`, `data` and `child`
subkeys. For `attribs` and `child`, these contain namespace subkeys.
`attribs` then has one level of associative name => value data (where
`value` is a string) after the namespace. `child` has tag-indexed keys
after the namespace, each member of which is an indexed array matching
this same format.

For example:
<pre>
// This is probably a bad example because we already support
// <media:content> natively, but it shows you how to parse through
// the nodes.
$group = $item->get_item_tags(\SimplePie\SimplePie::NAMESPACE_MEDIARSS, 'group');
$content = $group[0]['child'][\SimplePie\SimplePie::NAMESPACE_MEDIARSS]['content'];
$file = $content[0]['attribs']['']['url'];
echo $file;
</pre>
