Put XML string (node value) in server text file and retrieve and echo it again (PHP) -

Put XML string (node value) in server text file and retrieve and echo it again (PHP) -

This is my problem. I'm trying to get a value from the XML url (from last.fm api) Example For, the biography of an artist

I already know that I can do this just like (for Adele):

     This return:  
  Adele Laurie Blue Adkins, (born on May 5, 1988) is a Grammy Award-winning English & lt; A href = "http: //www.last.fm/tag/singer-songwriter" class = "bbcode_tag" rel = "tag" & gt; Singer-songwriter & lt; / A & gt; Enfield, its first album from North London, & lt; A title = "Adele-19" href = "http://www.last.fm/music/Adele/19" class = "bbcode_album" & gt; 19 & lt; / A>, was released in January 2008 and entered the UK Albums Chart # 1. This album has received platinum authentication four times in the UK and has sold 5,500,000 copies worldwide. The album included a hugely popular song & lt; A title = "Following Adele & pavements" href = "http://www.last.fm/music/Adele/_/Chasing+Pavements" class = "bbcode_track" & gt; Chasing down & lt; / A & gt; Edelley earned two Grammy Awards in February 2009 for Best New Artist and Best Female Pop Vocal Performance.    Now I would like to keep that result in a text file and store it in a folder on my website, for example: "http://mysite.com/artistdescriptions/adele Txt ".  
 I've already tried:  
  & lt ;? Php $ file_path = $ _SERVER ['DOCUMENT_ROOT']. '/ Artist name / adele.txt'; $ Xml = Simple XMLload_file ("http://ws.audioscrobbler.com/2.0/?method=artist.getinfo&artist=adele&ipi_key=b25b959554ed76058ac220b7b2e0a026"); $ Info = $ xml- & gt; Artist- & gt; Bio- & gt; Summary; File_put_contents ($ file_path, $ info); $ File_contents = file_get_contents ($ file_path); If (! $ File_contents)! {$ Data = unserialize ($ file_contents); $ Data echo; }? & Gt;    But it did not work unfortunately. Any help will be very much appreciated!  
 "post-text" itemprop = "text">  The echo call magic method __toString (), but is not serial, and the sequential permission is not allowed in the simple expression, so it is to throw exceptions.  
  $ info = $ xml- & gt; Artist- & gt; Bio & gt; Summary-> __ toString ();

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is

    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.
