PHP: Display associative array with proper index

Question

I've done a basic SQL query and then a WHILE loop in PHP to loop through them. I've roughly built what I want but the output isn't 100%

I'm close but not close enough. Any guidance on my actual output vs. desired?

All code snippets below.

I have got close with the following but it creates a new entry for each record rather than grouping them

$a["name"]["contacts"][] = array("name"=>$row["contact"],"address"=>$row["address_1"],"phone"=>array("type"=>$row["type"],"number"=>$row["number"]));

NOTES

A query can return one or many rows (contacts). Each contact could have multiple phone numbers against them (or just one). Hopefully this is obvious from the data below. I can't do this in SQL as I can only perform very simple SQL statements and no functions.

DATA FOR BELOW

Contact | Address_1 | Type              | Number
-------------------------------------------------
Barry   |           | Home Mobile Phone | 666
Barry   |           | Home Phone        | 888
Joanne  |           | Home Mobile Phone | 987654
Joanne  |           | Home Phone        | 123456

PHP

$res = RNCPHP\ROQL::query( "SELECT * FROM resource.contact_emergency WHERE collar = '".$row."'" )->next();
$a = Array();

while($row = $res->next()) {
    $a[$row["contact"]]["address"] = $row["address_1"]; 
    $a[$row["contact"]]["phone"][] = array("type"=>$row["type"],"number"=>$row["number"]);
}

Answer 1

Simply add the name to each associative array and then call array_values to convert $a into a simple array:

while($row = $res->next()) {
    $a[$row["contact"]]["name"] = $row["contact"]; 
    $a[$row["contact"]]["address"] = $row["address_1"]; 
    $a[$row["contact"]]["phone"][] = array("type"=>$row["type"],"number"=>$row["number"]);
}

$b['person'] = array_values($a);
