PHP数组和foreach帮助

Question

我需要一些帮助，数组和foreach循环，

我有一个数组，它是从数据库返回的数据，基本上是与之相关联的标题和图像的列表，它看起来有点像这样，

Array

<p>Bang has been working on developing Selectamark's range of product brands, which include the UK's leading asset tracking and labelling system Selectamark, and second generation forensic marking system, SelectaDNA.

<p>Chris Garratt, Marketing Director at Bang Marketing Ltd explained "Selectamark adopted a well planned, coordinated and consistent strategy in 2008, and the results speak for themselves.</p>

正如你可以看到contentTitle变化，每次但有时是返回相同的内容标题，我正在寻找一种方法来添加返回的数据之间的鸿沟，如果内容标题价值变化？

这可能吗？如何？我真的在这里挣扎。

感谢

Answer 1

如您遍历，你可以有一个临时变量来储存最后显示的标题

$lastTitle=''; 
foreach ($array as $record) 
{ 
    if ($lastTitle != $record['contentTitle']) 
    echo '<hr>'; 

    $lastTitle = $record['contentTitle'); 

    // display content from record 

} 

Answer 2

如果我理解正确的话，你希望每次contentTitle是显示分频器不同于它在上次迭代中的价值。
你在这里做一种画廊，是吗？ 如果是这样，我会这样想：

$lastTitle = ''; 
foreach($yourArray as $value) 
{ 
    if(!$lastTitle || $lastTitle != $value['contentTitle']) 
    { 
     echo '<h2>' . $value['contentTitle'] . '</h2><hr />'; // Display divider 
     // Do some other stuff 
    } 

    $lastTitle = $value['contentTitle']; 
    // Display image or whatever you want to do 
}
