Question

I am using array_chunk but i want to be able to echo something different for the first array in the chunk. Not sure on how to do this and could not find anything. Any help/guidance would be appreciated.

假设我使用：

     foreach (array_chunk($entries, 4) as $row) { 

    if (the array chunk is the first) {回响<div class="cn_page" style="display:block;"> ;}
    else {回响<div class="cn_page"> ;} 

}

完整代码如下：

回响

<div id="cn_preview" class="cn_preview"> ;

foreach($entries as $entry){
回响<div class="cn_content" style="top:5px;">
      <img src="newsslider/images/polaroidphotobar.jpg" alt=""/>
      <h1> .$entry->title. </h1>
      <span class="cn_date"> .$entry->modified. </span>
      <span class="cn_category"></span>
      <p> .$entry->text. </p>
      <a href="" target="_blank" class="cn_more">Read more</a>
      </div> ;     
}
回响</div> ;


回响<div id="cn_list" class="cn_list"> ;

foreach (array_chunk($entries, 4) as $row) { 

if (the array chunk is the first) {回响<div class="cn_page" style="display:block;"> ;}
else {回响<div class="cn_page"> ;}

foreach ($row as $entry) {
$i++;

if ($i == 1){回响<div class="cn_item selected"> ;}
else {回响<div class="cn_item"> ;}

回响<h2> .$entry->title. </h2>
<p> .$entry->text. </p>
</div> ;
回响</div> ; 

}
回响</div> ; 
}
echo <div class="cn_nav">
            <a id="cn_prev" class="cn_prev disabled"></a>
            <a id="cn_next" class="cn_next"></a>
</div>
</div>
</div> ;

那将是：

foreach (array_chunk($entries, 4) as $key => $row) { 
    if ($key == 0) {
        echo  <div class="cn_page" style="display:block;"> ;
    } else {
        echo  <div class="cn_page"> ;
    } 
}
