PHP multi array search and assign value to variable - php

Question

I have searched the forums up and down, tested as much as I can and still cannot find an answer to this problem. I need to assign a value to the following variables:
$custID = contactId;
$custFieldCityID = [customFieldValues][x][customFieldId]
$custFieldCity = [customFieldValues][x][value][x]
$custFieldStateID = [customFieldValues][x][customFieldId]
$custFieldState = [customFieldValues][x][value][x]
The order of the customFieldValues always changes (city can be in position 2, next array is in position 0, etc) and the customFieldId value is always different.
Here is the array I am getting (cannot be changed):
Array
(
[contactId] => V
[name] => Mrs Mder
[email] => xxx#verizon.net
[customFieldValues] => Array
(
[0] => Array
(
[customFieldId] => I
[name] => city
[value] => Array
(
[0] => Fairfax
)
[values] => Array
(
[0] => Fairfax
)
[type] => text
[fieldType] => text
[valueType] => string
)
[1] => Array
(
[customFieldId] => 8
[name] => postal_code
[value] => Array
(
[0] => 22032
)
[values] => Array
(
[0] => 22032
)
[type] => text
[fieldType] => text
[valueType] => string
)
[2] => Array
(
[customFieldId] => M
[name] => state
[value] => Array
(
[0] => VA
)
[values] => Array
(
[0] => VA
)
[type] => text
[fieldType] => text
[valueType] => string
)
[3] => Array
(
[customFieldId] => V
[name] => street
[value] => Array
(
[0] => 123 Holden Street
)
[values] => Array
(
[0] => 123 Holden Street
)
[type] => text
[fieldType] => text
[valueType] => string
)
[4] => Array
(
[customFieldId] => s
[name] => phone
[value] => Array
(
[0] => [phone]
)
[values] => Array
(
[0] => [phone]
)
[type] => text
[fieldType] => text
[valueType] => phone
)
)
)
So far I have tried this:
foreach($returncustdata as $row) {
foreach($row as $k) {
$fieldID= $k['customFieldValues']['customFieldId'];
$fieldname = $k['customFieldValues']['name'];
$fieldvalue = $k['customFieldValues']['value'][0];
}
}

You can index your customFieldValues by name for simpler access:
Use array_column with 2nd argument null and 3rd argument name to index that array by name field making it associative array.
To get first element from array no matter of it's key you can use current(). If it's always in 0th position, then no need for this.
$myArray['customFieldValues'] = array_column($myArray['customFieldValues'], null, 'name');
$custID = $myArray['contactId'];
$custFieldCityID = $myArray['customFieldValues']['city']['customFieldId'];
$custFieldCity = current($myArray['customFieldValues']['city']['value']);
$custFieldStateID = $myArray['customFieldValues']['state']['customFieldId'];
$custFieldState = current($myArray['customFieldValues']['state']['value']);
