How do i display RSS feeds in my php page?

LJackson · 10-15-2008, 03:39 PM

Hi All,

I have suscribed to some rss feeds and can view in windows live mail but how do i get my website to display the rss feeds?

here is one of the feeds url

http://ax.phobos.apple.com.edgesuite...15427%26url%3D

i know very little about rss,

i will also be calling these feeds from a database, so depending on which page is loaded the relivant feed is shown.

many thanks
Luke

LJackson · 10-15-2008, 05:34 PM

hi thanks for your reply, unfortunatly that link looks way to complex. plus i dont know how to get the xml file?

i dont know anything about rss, so please make everything as basic as possible

thanks

This is the simplest example I could come up with:

PHP Code:


			
<?php  
// rss page for Testing -  
$feed_url = "http://ax.phobos.apple.com.edgesuite.net/WebObjects/MZStore.woa/wpa/MRSS/topsongs/sf=143444/limit=25/rss.xml?partnerId=2003&TD_PARAM=http%3A%2F%2Fclkuk.tradedoubler.com%2Fclick%3Fp%3D23708%26a%3D1515427%26url%3D";

// INITIATE CURL. 
$curl = curl_init(); 

// CURL SETTINGS. 
curl_setopt($curl, CURLOPT_URL,"$feed_url"); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 0); 

// GRAB THE XML FILE. 
$xmlTwitter = curl_exec($curl); 

curl_close($curl); 

// SET UP XML OBJECT.
// Use either one of these, depending on revision of PHP.
// Comment-out the line you are not using.
//$xml = new SimpleXMLElement($xmlTwitter);
$xml = simplexml_load_string($xmlTwitter); 

// How many items to display 
$count = 10; 

// How many characters from each item 
// 0 (zero) will show them all. 
$char = 200; 

foreach ($xml->channel->item as $item) { 
if($char == 0){ 
$newstring = $item->description; 
} 
else{ 
$newstring = substr($item->description, 0, $char); 
} 
if($count > 0){ 
//in case they have non-closed italics or bold, etc ... 
echo"</i></b></u></a>\n"; 
echo" 
<div style='font-family:arial; font-size:.8em;'>  
<b>{$item->title}</b><br />
$newstring ... <a href='{$item->guid}'>read more</a> 
<br /><br /> 
</div> 
";  
} 
$count--; 
}  
?>

We of course are not sure of what XML tags you are interested in.

ok i quickly typed this up for you...simple enough .. ok

call your file rss.php or what ever you want

PHP Code:


			
<?php
header('Content-type: text/xml'); //change file type to XML
include("the database!");  //get config
?>
<rss version="2.0">
<channel>
    <title>Feed Name</title>
    <description>Feed Descriptiondescription>
    <link>http://yoursite.com</link>
<?
$result = mysql_query("SELECT * FROM entries ORDER BY id DESC"); //get the information
while($row = mysql_fetch_assoc($result)){ //repeat the info
?>
<item>
     <title><?=$row['title']; //echo the title
?></title>
     <description><?=$row[short]; //echo the content
?></description>
     <author>SiteName submissions@yoursite.com</author>
     <link>http://yoursite.com/index.php?id=<?=$row['id']; //another link to the article
?></link>
     <guid>http://yoursite.com/#<?=$row[id];// Quick Link
?></guid>
</item>
<?
} //end the while
?>
</channel>
</rss>

Be sure to change all your variables and upon checking it with W3C Feed Validator it is valid.
Now you have to edit your .htaccess file =P
Please add the code below so that instead of rss.php you could use news.xml or something else.

Code:

RewriteEngine On
RewriteRule ^(.*).xml$ rss.php

RunnerJP ...

I think they are looking for an RSS "Reader", not "Feeder".
But I like your feed example and may play with that one myself ... thanks for posting.

runnerjp · 10-15-2008, 07:29 PM

woops sorry miss understood

... thanks i do some erros in my codeing as you know by all my posts but sometimes i hit it right haha

Firstly Thanks Mate for doing this, what i dont understand is the xml file. where is it? how do i get it, is it a physical file that i should have or is it something that is pulled out of the rss feed? sorry for being dumb but i dont understand any of this rss stuff (but i will

)

your above code im getting an error:
Fatal error: Call to undefined function curl_init() in C:\wamp\www\Affiliate\rss.php on line 14

Neither do i mate

think i had better use them all until i get a feel for what im doing

thanks for you help so far much appreciated
Luke

LJackson · 10-15-2008, 10:16 PM

thanks for your code runnerjp but apparently its not what im looking for, i wouldnt have known if mlseim hadnt said

but thanks for trying to help i appreciate it.

mlseim · 10-16-2008, 03:22 AM

Your server (or webhost) must not have PHP CURL installed or enabled.

A web site that provides RSS feeds use their database to create an XML file.
The URL you gave us in the first post is a URL to their XML file. The XML file
is a specific set of tags that define XML.

An RSS reader opens that XML file and reads the fields (or tags) you're interested
in knowing. Once you read the tags, they can be displayed on your web page.

You might ask ... "why would a web site give out information for people to use on their own web site?" The answer is, with RSS, there are usually links back to the source.
So, it gives them links to their site, and some added traffic.

Here's an RSS feed I use to generate a little weather thing on a web page:
http://www.catpin.com/weather

Use Google to search more about RSS feeds.

About your script failing ... contact your web host about PHP CURL.

LJackson · 10-16-2008, 01:35 PM

ok i now understand the xml bit

thanks.

the curl error - might that be caused by the fact im on the local host at the moment?

cheers
Luke

mlseim · 10-16-2008, 02:48 PM

Luke ...

That might be it ... upload to a webhost and the CURL would work.
Most hosts now have CURL enabled.

More about XML ...

LJackson · 10-16-2008, 03:03 PM

my host does not support Curl damn One.com

are there any other ways around it?

mlseim · 10-16-2008, 05:01 PM

See if this works on your server ....

PHP Code:


			
<?php  
// rss page for Testing -  
$feed_url = "http://ax.phobos.apple.com.edgesuite.net/WebObjects/MZStore.woa/wpa/MRSS/topsongs/sf=143444/limit=25/rss.xml?partnerId=2003&TD_PARAM=http%3A%2F%2Fclkuk.tradedoubler.com%2Fclick%3Fp%3D23708%26a%3D1515427%26url%3D";

$xml = simplexml_load_file($feed_url);

// How many items to display 
$count = 10; 

// How many characters from each item 
// 0 (zero) will show them all. 
$char = 200; 

foreach ($xml->channel->item as $item) { 
if($char == 0){ 
$newstring = $item->description; 
} 
else{ 
$newstring = substr($item->description, 0, $char); 
} 
if($count > 0){ 
//in case they have non-closed italics or bold, etc ... 
echo"</i></b></u></a>\n"; 
echo" 
<div style='font-family:arial; font-size:.8em;'>  
<b>{$item->title}</b><br />
$newstring ... <a href='{$item->guid}'>read more</a> 
<br /><br /> 
</div> 
";  
} 
$count--; 
}


?>
