RSS feed

[runeveryday]

$feed=file_get_contents('URL');

$rss=new  SimpleXmlElement($feed);

foreach($rss->channel->item as $entry)

{echo "<p><a href='$entry->link' title='$entry->title'>" . $entry->title . "</a></p>";} 

who can tell me what the $rss->channel->item mean.

in php,i found state a class's format is

 

class classname{...;}

when refer the content of the class,the format is

$variablename=new classname, $variablename->the content of the class,however,in the above example,i found there is now state channel in SimpleXmlElement($feed);why?

i am a beginner of php and expect some can explain these details.

 

thank you!

The simplexml class will hold the properties of the xml document, no matter what it looks like (as long as it's proper xml). Channel and item is a result of the structure of RSS.

thanks for you response!what a pity,

i can't understand that.maybe i know XML and RSS not much.are there some articles can help me understand these.would you mind giving me some tips.

Exactly what is it that you don't understand? The structure of xml and rss or objects and classes? That's kind of two very different things

$rss is an object. channel could be a function of the object. item could be a variable of the object. Fairly simple if you understand OOP.
