A php function for reading remote files

A function for reading remote files, which is very useful! Function urlfopen ($ url, $ limit = 0, $ post = '', $ cookie ='', $ bysocket = FALSE, $ ip = '', $ timeout = 15, $ block = TRUE, $ encodetype = 'urlencode '){ $ Return = ''; $ Matches = parse_url ($ url ); $ Host = $ matches ['host']; $ Path = $ matches ['path']? $ Matches ['path']. (isset ($ matches ['query'])? '? '. $ Matches ['query']: ''):'/'; $ Port =!
