Add a 'break' in my php code

Question

Recently I am using php to deal with a xml file.

But I don't know how to add a 'break' in my code.

The link is : http://babystory.diandian.com/rss

I want to use php to get the article named '[x]快乐王子'.But "foreach()" give me the last article named '[1]狼和七只小山羊'.

I want to add a break in "foreach()" so that I can get the article I want.

Here is my php code:

<?php
$xml = simplexml_load_file("http://babystory.diandian.com/rss");

foreach($xml->children() as $child){}

foreach($child->children() as $child2)

foreach($child2->children() as $child3)
{
  $element = $child3->getName();
  if($element=='title')
  {
    echo "<h1>" . $child3 . "</h1>";
  }

  if($element=='description')
  {
    echo $child3;
  }
}
?>

Could you help me to edit my code.Thank you very much.

Simple use break statement. If you want break 2 cycles, use break 2; — designerrr

When I run you code, I get all three stories -- not just one. And what are you trying to accomplish exactly? Do you want to exit parsing once you hit that story? — Authman Apatira

I want to get one story from the xml.If you open the xml,you can see there are three <item> elements.I want to get the first one not the last one.But now I don't know how to achieve it. — CashLee李秉骏

If you need to get the first item from your feed you don't need any foreach loops at all.

$xml = simplexml_load_file("http://babystory.diandian.com/rss");
$item = (array)$xml->channel->item[0]; // the article [x]快乐王子 array

Now $item is array of the first article information. So $item['title'] is [x]快乐王子, $item['link'] is http://babystory.diandian.com/post/2012-01-15/14770976, etc.

Try this inside your last foreach....

i.e. .....

foreach($child2->children() as $child3){
   if($child3->getName() == "title" && $child3 == "THE TITLE I WANT"){
       $saveItem = $child3;
       break 3;
   }
}
echo $saveItem;
