Combine 2 place request to get postal code - php

Question

I would like to combine two place-api calls in one to get further information about listings.
Example:
My first script request provides Name and Address from the API. However, the Placesearch API does not provide the postal code or other information I need.
My current script shows me this:
name;adress,lnt,lng,place_id
but I need more information for each listing, like the postal code, which not included here.
How can I include a 2nd API call for each place_id and display the postal code?
$apikey = 'KEY';
$url = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=51.374,10.1495&rankby=distance&name=keyword&language=de&key=$apikey";
$json = file_get_contents($url);
$obj = json_decode($json, true);
for($i=0; $i<count($obj['results']); $i++) {
echo "" . $obj['results'][$i]['name'] . ";" . $obj['results'][$i]['vicinity'] . ";" . $obj['results'][$i]['geometry']['location']['lat'] . ";" . $obj['results'][$i]['geometry']['location']['lng'] . ";" . $obj['results'][$i]['place_id'] . DISPLaY POSTCODE "<BR>";
};
I know, I need to run this query for each place_id:
https://maps.googleapis.com/maps/api/place/details/json?placeid=$place_id=name,rating,formatted_phone_number&key=YOUR_API_KEY
But how can I combine it together with the first results? I need:
Name;Adress;Postcode;LAT;LNG;
Update:
1st request:
$apikey = 'KEY';
$url = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=51.374,10.1495&rankby=distance&name=keyword&language=de&key=$apikey";
$json = file_get_contents($url);
$obj = json_decode($json, true);
for($i=0; $i<count($obj['results']); $i++) {
echo "" . $obj['results'][$i]['name'] . ";" . $obj['results'][$i]['vicinity'] . ";" . $obj['results'][$i]['geometry']['location']['lat'] . ";" . $obj['results'][$i]['geometry']['location']['lng'] . ";" . $obj['results'][$i]['place_id'] . DISPLaY POSTCODE "<BR>";
};
this is one ex response from the first request, the ChIJidzOXaLBpEcRxEKHcEN9fuo is the place id which i have to request the details:
Flinsberger Sportplatz;Heilbad Heiligenstadt;51.3163051;10.1929773;ChIJidzOXaLBpEcRxEKHcEN9fuo
this is api call shows the neede details, which i need and can access:
https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJidzOXaLBpEcRxEKHcEN9fuo=name,rating,formatted_phone_number&key=YOUR_API_KEY
i need to include the 2nd request in the 1st, to get for ex. the postalcode for the specific item, which is my problem i dont know.
and the result should be:
name,adress,postalcode, ... , ... ,...

Answer 1

Following the comments, I came up with this. Note that I do not have an API key myself to test, the the idea is there. You might have to adjust the reference to $obj2 based on the result of the json_decode function for the second query (the one in the loop).
<?php
$apikey = 'KEY';
$url1 = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=51.374,10.1495&rankby=distance&name=keyword&language=de&key=$apikey";
$json1 = file_get_contents($url1);
$obj1 = json_decode($json1, true);
for( $i = 0; $i < count($obj1['results']); $i++)
{
$place_id = $obj1['results'][$i]['place_id'];
$url2 = "https://maps.googleapis.com/maps/api/place/details/output?json&key=" .$apikey . "&placeid=" . $place_id . "&fields=address_component"
$json2 = file_get_contents($url2);
$obj2 = json_decode($json2, true);
echo "" . $obj1['results'][$i]['name'] . ";" . $obj1['results'][$i]['vicinity'] . ";" . $obj1['results'][$i]['geometry']['location']['lat'] . ";" . $obj1['results'][$i]['geometry']['location']['lng'] . ";" . $obj1['results'][$i]['place_id'] . $obj2['result']['address_components']['postal_code'] . "<br>";
};
?>
The idea is you get the information you want form $obj1 and $obj2 based on the results of the 2 queries.
