Getting the distance between two locations using Google Maps Api (JSON) - php

For finding the first value of routes, you can use below code :-
$json_a['routes'][0]['legs'][0]['distance']['text']
If you want to show all values then use foreach.
For sorting on values
function cmp($a, $b)
{
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
$a = array(3, 2, 5, 6, 1);
usort($a, "cmp");
foreach ($a as $key => $value) {
echo "$key: $value\n";

you should first check if photo key is exist in $resp['results'][$i] array by using isset function in php
for example
if(isset($resp['results'][$i]['photos']) && count($resp['results'][$i]['photos']) > 0)
{
// write your code
}
and also you should use phpenter code here count function to check $resp['results'][$i]['photos'] array has multi entry
so you can write $resp['results'][$i]['photos'][0] without have out of scope error

getting array value from json array PHP

Checking at the structure of the json got from the call, to access the value you want to need to do like this.
$string = file_get_contents("https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&rankby=distance&types=food&key=AIzaSyCpOG91fkAzPTZiFq7G9HbLfbmVyW8Wgyc");
$json_a = json_decode($string, true);
print_r($json_a['results'][0]['name']));
Results is an array, and you want to access to its first element ([0]). From that first element you want to get the property name. And all the properties on the element are set inside an array, so you need to access it by the property name.
You were using the object operator (->) to access elements from an array, that's why it didn't work.

echo print_r(....); is in a way redundant. print_r it self prints result to output in similar way as echo and returns TRUE which is what you are printing.
From documentation:
mixed print_r ( mixed $expression [, bool $return = false ] )
When the return parameter is TRUE, this function will return a string. Otherwise, the return value is TRUE.
Either do not use echo or set the return param to TRUE.
echo print_r($array, true);

How to sort object array by value deep inside array

Use usort for this kind of sorting. It uses Quicksort in the background and takes a user-defined function to compare the array elements:
usort($array, "complicatedArrayComparer");
function complicatedArrayComparer($a,$b)
{
if ($a['field_device_category'] == $b['field_device_category']) {
return 0;
}
return ($a['field_device_category'] < $b['field_device_category']) ? -1 : 1;
}

How to get the Multidimensional array value in foreach loop using php [closed]

If I understood your question correctly, you would like to extract the Hotel Id, Name, and SellingPrice keys from this array, in a loop.
If we assume the above array is stored in a variable called $HotelData, and that the array structure is consistent with the above output in your question, then the following code should allow you to do what you want...
foreach($HotelData['HotelAvailability'] as $hotel) {
$id = $hotel['Hotel']['Id'];
$name = $hotel['Hotel']['Name'];
$price = $hotel['Result']['Room']['SellingPrice']['Currency'] . ' ' . $hotel['Result']['Room']['SellingPrice']['Amount'] ;
echo "$id - $name: $price<br>\n";
}
/* This should output something like
*
* 3027405 - Royal Plaza: INR 1824.26
* 2118726 - Days Inn Deccan Plaza - INR 3192.90
* ...
*/

foreach($data['HotelAvailability'] AS $record) {
echo 'Id: '; echo $record['Hotel']['Id'];
echo '<br />';
echo 'Name: '; echo $record['Hotel']['Name'];
echo '-------------'; echo '<br />';
}
