html form to REST URL to JSON to PHP

Hello Experts

I'm using a simple html form

<form method="post" action="myform.php">
<input type="submit" value="Submit">
<input type="text" name="varX">
</form>

At this moment this form outputs varX to myform.php

But i need varX to first go through a REST URL that produces a JSON

URL: http://some_external_site.com/?var=varX

This url outputs this JSON

{
 "var1": "success",
 "var2": "varX",
 "var3": false
}

I want var1, var2, var3 put into var's in myform.php so i can use it for other stuff.

I do not know how to begin with this.
But you guys do ?

Kind Regards

PHP can convert the responses to JSON without a third party processor. See reference.

What I don't understand is how you go from varX (one field) to var1, var2, var3 (three fields). Can you elaborate?

Hello xmediaman
The rest url is an api that returns those 3 vars in a json file when called with varX . See the url i mentioned.
this url is at an external site and is already operational

It sounds like you need myform.php to accept varx, then send it to the REST URL and process the returned JSON object. Unfortunately this is beyond my experience, but if this explanation is accurate, it might help Ray and other experts to present a solution to you.
