如何在PHP中回显WordPress标签

Question

在我的PHP中，我想将每个wordpress-post标记附加到URL的末尾。但它似乎返回了一个数组，并且不起作用。我所有的WordPress帖子每个只有一个标签。

<?php
$tags = get_the_tags();
$html= file_get_contents('https://www.trade-ideas.com/ticky/ticky.html?symbol=')**.'$tags'**;
$start = strpos($html,'<div class="span3 height-325"');
$end =  strpos($html,'<!-- /span -->',$start);
$data= substr($html,$start,$end-$start);
echo "$data" ;
?>

感谢所有我设法做到的

<?php
$post_tags = get_the_tags();
if ( $post_tags ) {
$tags = $post_tags[0]->name; 
}   
$html= file_get_contents('https://www.trade-ideas.com/ticky/ticky.html?symbol='. "$tags");
$start = strpos($html,'<div class="span3 height-325"');
$end =  strpos($html,'<!-- /span -->',$start);
$data= substr($html,$start,$end-$start);
echo "$data" ;
