parse json data from google maps html call to mysql database using php

I want to add the locality name from a google maps html call(below) to a specific php variable so that I can 1) store it in a mysql database and 2) display it as part of an echo statement (echo $locality).,-118.35220470764159&sensor=false

I have decoded the json data via: json_decode($data,true); statement.

Given the complexity of the multivariable array structure, I'd like to dive down and pull out a specific value if it exists. An example to help explain.

Here is the json data abreviated to save space:

"results" : [


"address_components" : [


"long_name" : "2917-2981",

"short_name" : "2917-2981",

"types" : [ "street_number" ]


"long_name" : "Runyon Canyon Rd",

"short_name" : "Runyon Canyon Rd",

"types" : [ "route" ]



"long_name" : "Hollywood Hills",

"short_name" : "Hollywood Hills",

"types" : [ "neighborhood", "political" ]



"long_name" : "Los Angeles",

"short_name" : "Los Angeles",

"types" : [ "locality", "political" ]



my code:


$data = @file_get_contents($url);

$phpresult = json_decode($data,true);


var_dump($phpresult) displays:

array(2) { ["results"]=> array(8) { [0]=> array(4) { ["address_components"]=> array(8) { [0]=> array(3) { ["long_name"]=> string(9) "2917-2981" ["short_name"]=> string(9) "2917-2981" ["types"]=> array(1) { [0]=> string(13) "street_number" } } [1]=> array(3) { ["long_name"]=> string(16) "Runyon Canyon Rd" ["short_name"]=> string(16) "Runyon Canyon Rd" ["types"]=> array(1) { [0]=> string(5) "route" } } [2]=> array(3) { ["long_name"]=> string(15) "Hollywood Hills" ["short_name"]=> string(15) "Hollywood Hills" ["types"]=> array(2) { [0]=> string(12) "neighborhood" [1]=> string(9) "political" } } [3]=> array(3) { ["long_name"]=> string(11) "Los Angeles" ["short_name"]=> string(11) "Los Angeles" ["types"]=> array(2) { [0]=> string(8) "locality" [1]=> string(9) "political" }...<

I'd like to store the value "Los Angeles" in variable $locality by searching/parsing/? the array for the condition "type = locality".

I do not want find the information by using the code:

echo $phpresult['results'][0]['address_components'][3]['long_name'];

because that assumes the variable is always 1) in the same location within the array and 2) that it exists.

Any help would be really appreciated. I haven't found an answer and have probably read (but not totally understood) every post relating to the subject.

Thanks in advance for your help.


Answer Source
foreach($phpresult['results'][0]['address_components'] as $location)
    if(in_array("locality" , $location['types']))
        $locality[] = $location['long_name'];


The array of each location has 3 keys: long_name , short_name and types. Types is an array , so , if there's a value of "locality" in that types array get the long_name of that location and store it.

EDIT: This function will store all the long_names of location which has a locality type, not just the first one. In order to get only the first location's long_name ,add "break" after the $locality[] = ....
