将数组存储到php中的变量中

Question

我在WordPress中运行以下SQL查询。

$mylink = $wpdb->get_results("SELECT `object_id` FROM `wp_term_relationships` WHERE `term_taxonomy_id` = (SELECT `term_id` FROM `wp_terms` WHERE `slug` LIKE 'jabong')");

显示值来自数组。

foreach($mylink as $key => $row) {
echo $row->object_id."<br>";
}

我得到了以下输出。 109957109834109952109964109670

我想将此值存储为String 109957,109834,109952,109964,109670。 所以请帮助我如何将这个值存储在字符串中。

Answer 1

$string = "";foreach($mylink as $key => $row) { $sting.=$row->object_id.",
"; }

$string = substr($string,0,-1);
