Answer 1

你可以使用PHP函数explode（），你可以阅读更多here

Answer 2

我使用了正则表达式，首先根据product/拆分字符串然后找到数字。

$jsonArr = json_decode($json, true);

$chars = preg_split('/product\//', $jsonArr['items'][0]['primary_image_url']);
preg_match('/^\d+/', $chars[1], $matches);
print_r($matches);
$chars2 = preg_split('/product\//', $jsonArr['items'][1]['primary_image_url']);
preg_match('/^\d+/', $chars2[1], $matches2);
print_r($matches2);
