Answer 1

<?php
$tag="jan,feb,mar,apr,may";
$tags = explode(',', $tag); //Explode tags into an array
foreach($tags as $vals)//Loop through tags
{
    ?>
    <a href="xyz.php?tag=<?php echo $vals; ?>"><?php echo $vals; ?></a>
    <?php //Echo onto page
}
?>

Answer 2

就这样做：

<?php
$tag='jan,feb,mar,apr,may';
foreach(explode(',', $tag) as $val){
echo '<a href="xyz.php?tag='.$val.'">'.$val.'</a><br>'; 
}
?>

Answer 3

您可以使用explode将它们放入数组中。

$tag = "jan,feb,mar,apr,may,jun,jul"; //etc

$months = explode(",", $tag);

爆炸功能会将$months设置为如下所示：

$months = [
    'jan',
    'feb',
    'mar',
    'apr',
    'may',
    'jun',
    'jul'
];

然后，您可以使用foreach循环播放您已创建的新阵列。

foreach($months as $month) {
    echo "<a href='xyz.php?tag=$month'>$month</a><br>";
}

Answer 4

您可以简单地用逗号分隔字符串以获得数月的数组。

现在，遍历数组并打印几个月的链接。

<?php
$tag="jan,feb,mar,apr,may";
$tags = explode(',', $tag);
if (! empty($tags)) {
  foreach ($tags as $tag) {
  ?>
  <a href="xyz.php?tag=<?php echo $tag;?>"><?php echo $tag;?></a>   
  <?php
  }
}
?>

Answer 5

foreach (explode(",", $tag) as $month) { //split by comma
echo '<a href="xyz.php?tag=' . $month . "</a>\n"; //just echo it
}

Answer 6

一种“功能性”方法，利用explode()，array_map()和implode()：

$tags="jan,feb,mar,apr,may";
echo implode("\n",array_map(function($tag) {
    return "<a href=\"xyz.php?tag=$tag\">$tag</a>";
}, explode(',',$tags)))

或者，在array_reduce()的帮助下，无需额外拨打implode：

$tags="jan,feb,mar,apr,may";
echo array_reduce(explode(',',$tags), function($acc, $tag) {
    return $acc."<a href=\"xyz.php?tag=$tag\">$tag</a>\n";
}, '')

当然，如果你已经有数组格式的标签，那么你可以跳过explode。
