Php Foreach：为指定行数添加换行符（段落）的正确方法

我在mysql数据库中有一堆随机的句子，我可以用下面的代码将它们提取出来并显示出来，但是，我在下一个过程中遇到了难题

如何为每X行添加nl或封装在标记中？选定的行已经限制为14行（任意），我的目标是将这14行每3或4行添加一个换行符（也是任意的），这样它们看起来更流畅

    <?php 
include $_SERVER['DOCUMENT_ROOT'] . '/dbConnect.php';
$q = $dbc->query("SELECT DISTINCT sentence FROM sentences ORDER BY rand() LIMIT 14");

    while($r = $q->fetch_array(MYSQLI_ASSOC)):
    foreach($r as $value) {
$value = str_replace('$keyword', '<b>replaced keyword</b>', $value);
echo $value." ";  
    }

    endwhile;

?>

但是，我希望它能做更多类似的事情，而不会创建一个低效的3块相同的代码，限制为3、2、4或类似的代码

This is a complete sentence that I'm outputting to the page.
This is a complete sentence that I'm outputting to the page.
This is a complete sentence that I'm outputting to the page.

This is a complete sentence that I'm outputting to the page.
This is a complete sentence that I'm outputting to the page.

This is a complete sentence that I'm outputting to the page.
This is a complete sentence that I'm outputting to the page.
This is a complete sentence that I'm outputting to the page.
This is a complete sentence that I'm outputting to the page.

我想这就是你想要的：

<?php 
include $_SERVER['DOCUMENT_ROOT'] . '/dbConnect.php';
$i=0; $j=0;
$seq=array(3, 2, 4);
$q = $dbc->query("SELECT DISTINCT sentence FROM sentences ORDER BY rand() LIMIT 14");

    while($r = $q->fetch_array(MYSQLI_ASSOC)):
    foreach($r as $value) {
         $value = str_replace('$keyword', '<b>replaced keyword</b>', $value);
         echo $value."<br>";
         if($i==$seq[$j])
         {
             echo "<br>";
             $j++;
             $i=0;
             if($j==count($seq)) $j=0;
          } else {
             $i++;
          }
    }
    endwhile;
?>

希望有帮助

以下是我对你的问题的看法：

$numberOfSentencesPerParagraph = 4; // specify
$totalNumberOfSentences = 14; // or use a count function to calculate the number of returned MySQL records // or make this equal to a new variable you will introduce in your SQL query (after `LIMIT`)
while($r = $q->fetch_array(MYSQLI_ASSOC)):
    $theCounter = 1;
    foreach($r as $value) {
        $value = str_replace('$keyword', '<b>replaced keyword</b>', $value);
        echo $value." ";  
        $theCounter++;
        if(($theCounter % $numberOfSentencesPerParagraph) == 0){
            echo "<br>";
        }
    }
endwhile;

$numberOfSentencesPerParagraph=4；//具体说明
$TotalNumberOfSequences=14；//或者使用count函数计算返回的MySQL记录数//或者使其等于将在SQL查询中引入的新变量（在“LIMIT”之后）
而（$r=$q->fetch_数组（MYSQLI_ASSOC））：
$theCounter=1；
foreach（$r为$value）{
$value=str_replace（“$keyword”，“replaced keyword”，“$value”）；
回声$value.“；
$theCounter++；
如果（$theCounter%$NumberOfSentenceSperparGraph）==0）{
回声“
”；
}
}
结束时；

它只是运行一个“计数器”，当它的值是变量的倍数时，它就会发出一个换行符

$numberOfSentencesPerParagraph = 4; // specify
$totalNumberOfSentences = 14; // or use a count function to calculate the number of returned MySQL records // or make this equal to a new variable you will introduce in your SQL query (after `LIMIT`)
while($r = $q->fetch_array(MYSQLI_ASSOC)):
    $theCounter = 1;
    foreach($r as $value) {
        $value = str_replace('$keyword', '<b>replaced keyword</b>', $value);
        echo $value." ";  
        $theCounter++;
        if(($theCounter % $numberOfSentencesPerParagraph) == 0){
            echo "<br>";
        }
    }
endwhile;
