如何在php中指向api的url中间有变量？

Question

我想添加一个$ var [5],它包含字符串值到以下url的{subscription_reference}部分.

$url5 = $api_entry_point ."/subscription/{subscription_reference}/credentials";

它需要像这样..

$url5 = $api_entry_point ."/subscription/0997f4ea6b6ca709/credentials";

我尝试了不同的方法,但都出了问题.那些都是

$url5 = $api_entry_point ."/subscription/'.$var[5].'/credentials";

$url5 = $api_entry_point ."/subscription/$var[5]/credentials";

Answer 1

试试这个 :

$url5 = $api_entry_point."/subscription/".$var[5]."/credentials";
