Break a Foreach Loop - El Forum - 09-09-2009

I have a loop coming down from an RSS reader and basically I want to break the loop once it has reached a certain number of entries. How do I do this with PHP?
Code:
<?php foreach ($rss as $item):?>
<li><a >get_link(); ?>"><?php echo $item->get_title(); ?></a></li>
<?php endforeach; ?>I have something along the lines of...
Code:
<?php
$limit = 8;
for($constrict = 1; $constrict <= 10; $constrict++)
if($limit > 8)
{

Code:
if($limit > 8)
{
break;

Thanks, but I'm having trouble applying the break to the foreach loop.

I don't understand how to break the loop after eight entries.

I think you should fix your query so that $items is only as big as you need. It's detrimental to get 100 rows if you are only going to show 8 of them
Code:
$this->db->limit(8);@noxie: not have your coffee yet? lol $limit is not being updated anywhere, i think you mean
Code:
if($constrict >= 8)
{
break;
}As for the second example another(better?) way would be :
Code:
<?php
$limit = 8;
for($constrict = 1; $constrict <= $limit; $constrict++)

I'm using SimplePie to read RSS feeds off the New Scientist website but I can't find the variable to limit the number of feeds displayed, the documentation only helps if your using multiple feeds.

ok, it's pretty easy
Code:
<?php $limit = 8; ?>
<?php foreach ($rss as $item):?>
<?php $counter++; ?>
<li><a >get_link(); ?>"><?php echo $item->get_title(); ?></a></li>
<?php if($counter >= $limit) break; ?>
<?php endforeach; ?>i think.... i don't use the alternative foreach syntax

No, I genuinely did not understand how one could not get 'break' to work.

First of all, where do you get the $css array? Could you show how it, print_r().
The best solution would probably be to render $rss right from starters. But you could use this as simple fix until you do.
Code:
$rss_temp = array_chunk($rss ,8 ,TRUE);
$rss_chunk = $rss_temp[0];
