morrisjohnny Posted March 4, 2007 Share Posted March 4, 2007 I've started to learn PHP and i've been improving my knowledge. I'm currently trying to create An RSS reader using PHP. I have tried searching the forums but i can't search for 'PHP RSS reader' as PHP and RSS are below for words.I'm using the current code below i found online but it shows the full page. I only want to retire the title and the link. <?phpset_time_limit(0);$file = "http://newsrss.bbc.co.uk/rss/sportonline_uk_edition/motorsport/formula_one/rss.xml";$rss_channel = array();$currently_writing = "";$main = "";$item_counter = 0;function startElement($parser, $name, $attrs) { global $rss_channel, $currently_writing, $main; switch($name) { case "RSS": case "RDF:RDF": case "ITEMS": $currently_writing = ""; break; case "CHANNEL": $main = "CHANNEL"; break; case "IMAGE": $main = "IMAGE"; $rss_channel["IMAGE"] = array(); break; case "ITEM": $main = "ITEMS"; break; default: $currently_writing = $name; break; }}function endElement($parser, $name) { global $rss_channel, $currently_writing, $item_counter; $currently_writing = ""; if ($name == "ITEM") { $item_counter++; }}function characterData($parser, $data) { global $rss_channel, $currently_writing, $main, $item_counter; if ($currently_writing != "") { switch($main) { case "CHANNEL": if (isset($rss_channel[$currently_writing])) { $rss_channel[$currently_writing] .= $data; } else { $rss_channel[$currently_writing] = $data; } break; case "IMAGE": if (isset($rss_channel[$main][$currently_writing])) { $rss_channel[$main][$currently_writing] .= $data; } else { $rss_channel[$main][$currently_writing] = $data; } break; case "ITEMS": if (isset($rss_channel[$main][$item_counter][$currently_writing])) { $rss_channel[$main][$item_counter][$currently_writing] .= $data; } else { //print ("rss_channel[$main][$item_counter][$currently_writing] = $data<br>"); $rss_channel[$main][$item_counter][$currently_writing] = $data; } break; } }}$xml_parser = xml_parser_create();xml_set_element_handler($xml_parser, "startElement", "endElement");xml_set_character_data_handler($xml_parser, "characterData");if (!($fp = fopen($file, "r"))) { die("could not open XML input");}while ($data = fread($fp, 4096)) { if (!xml_parse($xml_parser, $data, feof($fp))) { die(sprintf("XML error: %s at line %d", xml_error_string(xml_get_error_code($xml_parser)), xml_get_current_line_number($xml_parser))); }}xml_parser_free($xml_parser);// output as HTMLprint ("<html><head><title>PHP RSS Reader</title></head><body>");if (isset($rss_channel["IMAGE"])) { print ("<a href=\"" . $rss_channel["LINK"] .

"</i><br><br>");if (isset($rss_channel["ITEMS"])) { if (count($rss_channel["ITEMS"]) > 0) { for($i = 0;$i < count($rss_channel["ITEMS"]);$i++) { print ("\n<table width=\"100%\" border=\"1\"><tr><td width=\"100%\"><a href=\"" . $rss_channel["ITEMS"][$i]["LINK"] .

"</i>"); print ("</td></tr></table><br>"); } } else { print ("<b>There are no articles in this feed.</b>"); }}print ("</body></html>");?> I want to display a maxium of three titles and hyperlinks but i would like it layout out like this <table><tr><td><a href='exteral_link_1'>Item1</a></td></tr><tr><td><a href='exteral_link_2'>Item2</a></td></tr><tr><td><a href='exteral_link_3'>Item3</a></td></tr></table> Link to comment Share on other sites More sharing options...
boen_robot Posted March 4, 2007 Share Posted March 4, 2007 I can't help saying it, so I'll just say it. Use XSLT for that. It's a lot easier to read and tweak, and the best part is it can run in conjuction with any S3L, including PHP.Look at this post. You can see how little the PHP code is. Of course, the XSLT is big, but it's written in declarive fashion and in pure markup. There are only a few tweaks needed to make this work with RSS 2.0 and a few more to make it the layout you want.The small tweaks for RSS are the line: <xsl:when test="*[name()=$pagedElement]"> that you must replace with: <xsl:when test="channel/*[name()=$pagedElement]"> and also change <xsl:for-each select="*[name()=$pagedElement and position()>=1+ $startPoint and position()<=$startPoint + $recordsPerPage]"> with: <xsl:for-each select="channel/*[name()=$pagedElement and position()>=1+ $startPoint and position()<=$startPoint + $recordsPerPage]"> As for your layout... try it and then search through the XSLT. It won't be long until you understand the process. Link to comment Share on other sites More sharing options...
Anders Moen Posted March 4, 2007 Share Posted March 4, 2007 I got a code for reading RSS in a PHP file today: <?// We make a new object$obj = new db();//Så kaller vi opp funksjonene våre$obj->koble_til();$obj->skrivut();$obj->steng_db();// CONNECTclass db{//Noen variablervar $hostname = "localhost";var $username = "your_username";var $password = "your_password";var $usertable = "your_table";var $dbName = "your_database_name";var $result;function koble_til(){// Connecting ...mysql_connect($this->hostname,$this->username,$this->password) || die(mysql_error());@mysql_select_db($this->dbName) || die("Unable to select database");}function query($query){$data = array();$this->result = mysql_query($query);if(mysql_num_rows($this->result) != 0){ while($d = mysql_fetch_object($this->result)){ $data[] = $d; } return $data;}return null;}function skrivut(){$result = $this->query("SELECT * FROM $this->usertable ORDER BY id");if (!is_null($result)){ $now = date('d.m-Y@H:i:s', time()); $rss = <<<RSS <rss version="2.0"> <channel>\n <title>Anders Moen :: News</title> <description>Anders Moen's RSS feed</description> <lastBuildDate>$now</lastBuildDate> <link>http://andersmoen.hotserv.dk/new/</link>RSS; foreach($result as $r){ $date = date('d/m/Y@H:i:s', $r->timestamp); $rss .=<<<RSS <item> <title>$r->title</title> <pubDate>$r->date</pubDate> <description>$r->content</description> <link>http://andersmoen.hotserv.dk/new/?page=view&id=$r->id</link> </item>RSS; } $rss .="</channel></rss>";header('Content-type:text/xml');print $rss;}}function steng_db(){mysql_free_result($this->result);mysql_close();}}?> Some of the explanations here is in Norwegian since I got it on a Norwegian forum today.Well, wanna see it?

boen_robot Posted March 4, 2007 Share Posted March 4, 2007 That's not an RSS reader! It's MySQL to RSS generator. There's quite a difference. Link to comment Share on other sites More sharing options...

Mr_CHISOL Posted March 6, 2007 Share Posted March 6, 2007 You could use SimpleXML (http://php.net/manual/en/ref.simplexml.php) to extract the information from the structure.How exactly to do this is hard to tell without the complete structure (as it the part you gave us doesn't seam to be "alone", if it is so you need to add a root element).Here's an example using the info you gave (with a "unknown root", you don't need to know it's name using SimpleXML as this): <?php$xml = new SimpleXML( $structure ); // Can parse a string or open a file, see the manualecho '<a href="'.$xml->link.'" target="_blank">'.$xml->title.'</a>';?> to get the three first you can use a for-loop: <?php$xml = new SimpleXML( $structure ); // Can parse a string or open a file, see the manualfor ($i = 0; $i < 3; $++) { echo '<a href="'.$xml->post[$i]->link.'" target="_blank">'.$xml->post[$i]->title.'</a>';}?> This will work if the structure looks something like this (But it'snt hard to adapt to another structure) <root> <post> <title>...</title> <description>...</description> <link>...</link> </post> <post> <title>...</title> <description>...</description> <link>...</link> </post> <post>.....</root> Hope that helped.Good Luck and Don't Panic!

Nakor Posted March 6, 2007 Share Posted March 6, 2007 Well if all that you want is a working PHP RSS Reader/Parser then you should have just searched on Google. Here are 2.http://www.phpfreaks.com/script/view/703.phphttp://lastrss.oslab.net/However, you should know that if you simply use these and don't even read through them and attempt to understand them then you are not learning anything and you will not increase your skill at coding PHP.
