如何跳过foreach循环中的第一个实例并将其限制为8？

Question

I was wondering if anyone could give me a hand with this... Basically I am trying to modernize the news system of my site but I can't seem to limit the amount of posts showing in the foreach loop that is on my blog part of the site. I need to skip the first instance as it is already promoted at the top of the page. I've tried various google searches but im getting results for C++ Perl and python, what is really irritating. I just need a simple PHP solution. I'll pop my code below and see if anyone can help. Thanks for any help in-advance. And please remember to leave your responses as an answer so I can mark them up if they helped ;)

<div class="view22 full" style="margin-top:0;">
    <h3>Recent News and Announcements</h3>
    <?php foreach ($articles as $article) { 
?>
        <div class="ah7_ clearfix">
            <p class="date"><?php echo date('F j', $article['article_timestamp']); ?>, <?php echo date('Y', $article['article_timestamp']); ?></p>
            <h3><a href="<?php echo $url.'/newsroom/'.$article['article_id']; ?>"><?php echo $article['article_title']; ?></a></h3>
        </div>
    <?php 
    }
?>
</div>

Answer 1

I assume that the $articles array has keys starting with 0. How about modifying the loop like this:

foreach ($articles as $key => $article) 

and checking if $key is 0 at the beginning?

if($key == 0)
   continue;

If the array keys are different: Create a new variable $i, set it to 0 and increase the value by 1 in every foreach loop iteration.

$i = 0;
foreach ($articles as  $article) {
   $i++;
   if($i == 1)
      continue;
   elseif($i > 8)
      break;

   //the other code goes here
}

In case it is based on a SQL query, using "limit" might help to reduce load!

Answer 2

To remove the first instance you can manually unset the item ($articles[0]) after making a copy of it or printing it as a featured news.

To limit the number of post you can use the mysql LIMIT Clause;

Or you can do something like this

foreach($articles as $key => $article){
    if($key===0)
        continue;
    if($key===8)
        break;
    echo $article;// or_do_whatever_youwant_with($article);
}

Answer 3

There are a few things you can do:

1. If you $articles is an array of array, having continous indexes, use a for loop instead of foreach and do something like

    for ($i = 1; $i < 8 : $i++ ) { // and access it like $articles[$i]['some_index'] ... } 

2. If it is not then you can use an external counter Say

     $counter = -1; foreach ( $articles as $article) { $counter++; if (!$counter) continue; if ($counter > 7 ) break; ...// your code // } 

3. You can change your Mysql query to give you only the desired data, using LIMIT and OFFSET
