PHP: Separate array with commas
提问by Cameron
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.
我有这段代码应该显示一个数组中的值列表，后跟一个逗号和空格！但是我不希望最后一个后面有逗号和空格。
So for example I want tag1, tag2, tag3instead of tag1, tag2, tag3,
所以例如我想要tag1, tag2, tag3而不是tag1, tag2, tag3,
This is my code:
这是我的代码：
<?php $terms = get_the_terms( $the_post->ID, 'posts_tags' );
foreach ( $terms as $term ) {
echo $term->name;echo ", ";
} ?>

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