PHP：单独的数组用逗号 [英] PHP: Separate array with commas

问题描述

我有这样的code应该从一个阵列后跟一个逗号和空格显示值的列表！不过，我不希望是最后一个有后一个逗号和空格。

例如，我想 TAG1，TAG2，TAG3 而不是 TAG1，TAG2，TAG3，

这是我的code：

 ＆LT; PHP $学期= get_the_terms（$ the_post-＆GT; ID，'posts_tags'）;
                                的foreach（$条款$项）{                                    回声$ term-＆GT;名;回声，
                                ？}＆GT;
 

解决方案

  $输出=阵列（）;
的foreach（$条款$项）{
  $输出[] = $ term-＆GT;名;
}
回声破灭（''，$输出）;
 

I have this code that should display a list of values from an array followed by a comma and space! However I don't want the last one to have a comma and space after it.

So for example I want tag1, tag2, tag3 instead of tag1, tag2, tag3,

This is my code:

<?php $terms = get_the_terms( $the_post->ID, 'posts_tags' );
                                foreach ( $terms as $term ) {

                                    echo $term->name;echo ", ";
                                } ?>

解决方案

$output = array();
foreach($terms as $term){
  $output[] = $term->name;
}
echo implode(', ', $output);
