WordPress 回显数组 [英] WordPress echo out array

问题描述

我有以下代码行: $terms = get_the_terms( $the_post->ID, 'posts_tags' );echo $terms; 这个想法是以标签的格式回显数组，而不是它只返回单词Array?

I have the following line of code: $terms = get_the_terms( $the_post->ID, 'posts_tags' ); echo $terms; The idea is to echo out the array in the format of the tags but instead it just returns the word Array?

我该怎么做?标签应如下所示:'tag1, tag2, tag3'

How do I do this? The tags should be presented like this: 'tag1, tag2, tag3'

推荐答案

try

foreach($terms as $term){
    echo $term;
}

您可能想添加一些东西来分隔它们，例如 $echo "," 或其他东西，但您明白了
你也可以用这个

you might want to add something to separate them, like a $echo "," or something, but you get the idea
You can also use this

$termsString = implode (',' , $terms);
echo $termsString;

根据要求:

条款确实是一个数组，例如，请参阅@ProdigySim 对其外观的回答.您确实可以使用 var_dump 或 print_r 出于调试目的打印它们，但这在生产环境中对您没有帮助.

The terms is indeed an array, see for instance @ProdigySim 's answer for how it looks. You could indeed print them for debuggin purposes with var_dump or print_r, but that would not help you in a production environment.

假设它不是一个关联数组，你可以像这样找到第一个标签:

Assuming that it is not an associative array, you could find the first tag like this:

echo $terms[0]

其他都喜欢

echo $terms[1]

一直到最后一个 (count($terms)-1).
foreach 按顺序打印每一个.第二个，正如您在 手册 中找到的那样，只制作其中的一个字符串.

Right up until the last one (count($terms)-1).
The foreach prints each of these in order. The second, as you can find in the manual just makes one string of them.

最后，正如您在评论中所问的那样:只需粘贴即可.

In the end, as you asked in the comments: Just paste this.

$terms = get_the_terms( $the_post->ID, 'posts_tags' ); 
$termsString = implode (',' , $terms);
echo $termsString;
