请使用PHP

Answer 1

这将根据您的JSON进行。

echo ['results'][0]['title']['rendered']; //Title
echo ['results'][0]['content']['rendered']; //Content

Answer 2

你有一个多维数组，所以你要从中获取数据。

$arr = WpApi::posts();
$arr['results'][0]['content']['rendered'] //this is your content string
$arr['results'][0]['title']['rendered'] // this is your title string

如何从此var_dump提供的JSON数据数组中提取值
