循环中的数组，并按组显示数据 - Array in loop and show data by groups

Array in loop and show data by groups

本文关键字：显示数据数组循环 | 更新日期: 2023-09-27

我尝试按组在循环中显示数据，实际上我有一个包含许多元素的数组，需要在4、5等的组中显示

我举了一个例子：

$array_values=array(
  "2","3","5","2","3","5","2","3","5","2","3","5","2","3","5","2","3",
  "5","2","3","5","2","3","5","2","3","5","2","3","5"
);
$c=0;
foreah($array_values as $array_value) {
  print $array_value
  if($c%3) {
    print "<br><br>";
  }
  $c++;   
}

正如你在例子中看到的，在这种情况下，我想放"<br>"，循环中的每个3个元素，在其他情况下可以是每个4个或更多的元素，我尝试了这个，但没有得到好的结果，在某些情况下显示良好，在其他情况下显示所有糟糕的

我不知道该怎么做，感谢的帮助

与所有解决方案一样，有多种方法可以做到这一点。

您可以使用array_slice从数组中一次获取值3。

for ($c = 0; $c < count($array_values); $c+=3)     {
    print(implode(array_slice($array_values, $c, 3)));
    print "<br><br>";
}

您还可以使用array_chunk将阵列分解为3位段：

foreach (array_chunk($array_values, 3) as $row) {
    print(implode($row));
    print "<br><br>";
}

您需要检查$c%3的余数是否为0。但如果你想在另一种情况下增加另一个长度，你就必须加上它。但这应该让你开始。

$array_values=array("2","3","5","2","3","5","2","3","5","2","3","5","2","3","5","2","3","5","2","3","5","2","3","5","2","3","5","2","3","5");
$c=1;
foreach($array_values as $array_value)
{
    print $array_value;
    if($c%3 === 0)
    {
        print "<br><br>";
    }
    $c++;   
}

运行时，我会得到以下输出：
