Help me with a php post to google geolocation API

Hi,

I need help with a simple task of building a PHP webpage that run a post request on the google geolocation API as seen on https://developers.google.com/maps/documentation/geolocation/overview

and prints the result fields on the page using echo.

prerequisite: you must have a google api key to test it on your side as I will not disclose mine.

my data for testing the project is:

sample data

{
"wifiAccessPoints": [
{
"macAddress": "04:bd:88:4d:66:e0",
"signalStrength": -43,
"signalToNoiseRatio": 0
},
{
"macAddress": "44:48:c1:a6:f3:d0",
"signalStrength": -55,
"signalToNoiseRatio": 0
}
]
}
