使用引号将php变量格式化为php字符串

Question

I've tried multiple ways to format this http string, like escaping the " that are present in "user" and the user's name, but the API I'm connecting to will not work with anything but %22, so:

https://url.com/search/search?p=[{"user":"abc123"}]

has to be formatted like this:

curl_setopt($ch, CURLOPT_URL, 'https://url.com/search/search?p=[{%22user%22:%22abc123%22}]');

into this:

I need to replace %22abc123%22 with the actual user from a PHP variable, so the code looks like this:

[{%22user%22:%22 $phpVariable %22}]');

and is still enclosed in the %22, but I cannot figure out how to get the variable into the string without causing the string to give me an error. How do I do this (very simple) task?

Answer 1

I'm not sure why this is, as I generally enclose things in single quotes, but when I enclosed the string in double quotes, it worked as it normally would, so my string is:

curl_setopt($ch, CURLOPT_URL, "https://url.com/search/search?p=[{%22user%22:%22$phpVariable%22}]");
