remove_channel
-- Removes
an existing channel from ReachRSS (unsubscribes ReachRSS from an existing
RSS/RDF feed)
Description
boolean remove_channel ( string channel_url )
This function removes the specified channel from ReachRSS. The channel will no longer be monitored and any cached items / images will be deleted. Removing a channel is the same as "unsubscribing from an RSS feed" (many RSS readers use this terminology). remove_channel() automatically calls save_data() upon successful removal of the channel.
remove_channel() returns true on success, false on failure (if there was a problem saving the data file). If the specified channel never existed, remove_channel() will return true without actually doing anything.
Example 1. remove_channel() example
$ReachRSS = new ReachRSS();
$ReachRSS->Startup();
$ReachRSS->add_channel("http://www.comicalert.com/public/popular24.xml");
$ReachRSS->remove_channel("http://www.comicalert.com/public/popular24.xml");
This example will subscribe ReachRSS to the "most popular comics" feed at Comic Alert! and then immediatly remove it.
