limiting displayed items

Hi 1st question from me for the board

Trying to limit the number of items displayed from an XML feed

using simplexml:

$xml = simplexml_load_file('feed.xml');    
	foreach ($xml->channel->item as $item)

PHP:

I have tried:

$item = array_slice($xml->item, 0, 3);

PHP:

which gives an error

and

$count = 1; 
	for ($x = 0; $x < $count; $x++);

PHP:

Which shows the last result from the feed.

Any ideas where I am going wrong - ideally I just want display the 1st item, but am looking for something that could display 1, 2, 3 items etc...

Help muchos appreciated.

 

A little crude but you could simple add a counter and if() statement to break out of the loop depending on the counter value

$cnt = 0;
for($items as $item){
// your code

// some condition
if(++$cnt == 1) break;

}

Cheers mrmonster , I tried your suggestion, code looks like:

	<?php    
	$cnt = 0;
	for($items as $item)
	{
	$xml = simplexml_load_file('feed.xml');    
	foreach ($xml->channel->item as $item);
	if(++$cnt == 1) break;
	}
	
	{
	echo " ";   
  	echo " ";  
	}    
	?>

PHP:

Unfortunately it did not work - is there a problem with the syntax here - i am still learning with PHP and am a relative noob

 

Do you mean this?

<?php    
	$cnt = 0;
	$xml = simplexml_load_file('feed.xml');    
	foreach ($xml->channel->item as $item){
		if(++$cnt == 1){
			break;
		}
	}
?>

PHP:

 

Your logic doesn't seem right here, you have a loop within a loop and both of them are creating $item.

This might make it a little simpler, it will loop max_items number of times and exit, assuming your $xml object is valid.

$cnt = 0;
$max_items = 1;
$xml = simplexml_load_file('feed.xml');    
foreach ($xml->channel->item as $item){

	// insert code to process your $item here

	if(++$cnt == $max_items) break;
}

k+ to you mrmonster

That last snippet fixxed it.

Working now - DANKE!
