Creating and using a multi-dimensional array from MySQL - php

Question

Here's the line I'm having issues with:
array('jsonrpc' => '2.0', 'id' => 1, 'method' => 'getExchangeAmount', 'params' => array(array('from' => 'BTC', 'to' => 'LTC', 'amount' => '1'),array('from' => 'BTC', 'to' => 'ETH', 'amount' => '1')))
This is the specific part of the line I'm having issues with:
array(array('from' => 'BTC', 'to' => 'LTC', 'amount' => '1'),array('from' => 'BTC', 'to' => 'ETH', 'amount' => '1'))
Basically I'm using this script to compare prices of cryptocurrencies. The problem is that right now I'm having to enter all of them into the script manually.
However, I have a database table (trade_stats) that I'd prefer to get the details from.
Here's its layout:
id incoming outgoing
1 BTC ETH
2 BCH LTC
3 ETH BCH
What I'm wanting to do is pull the rows from my database and use them in the script, but I can't seem to figure out how to create a multi-dimensional array.
Any help or pointers in the right direction would be great.

I hope this helps you
<?php
$conn=new mysqli($dbhost,$dbuser,$dbpass,$dbname);
if (!$conn) {
die("Error Connecting To Database: ".mysqli_connect_error()."<br/>");
}
$sql="
SELECT * FROM trade_stats
";
$result=mysqli_query($conn,$sql);
if (mysqli_num_rows($result) > 0) {
while($row=mysqli_fetch_assoc($result)) {
$from=$row['incoming'];
$to=$row['outgoing'];
//$amount=$row['???'];
$array=array();
array_push($array, array('from' => $from, 'to' => $to, 'amount' => '1'));
print_r($array);
}
}
?>
I didn't set a value for mysqli connect so you can edit it yourself and suit it for your database.
+I don't know which column is for ((amount)) so I set 1 value for it.You can edit it yourself.
If you had any questions or if the code is not working as you wanted tell me I will edit it :)
