Dynamic Array with PHP - php

Question

Post Updated
I would like to create dynamic Array in PHP to provide the same output like static Array below, I have tried to do it with while statement but it doesn't work. Could you please provide me some tips?
I would like to use 2 values from MySQL and save them in to $to variable
so first send_to1 (user account) and then value1 (amount)
<?php
$con=mysqli_connect("localhost","test","test","test");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM users");
$to=Array(
while($row = mysqli_fetch_array($result))
{
$send_to1 => $value1,
$send_to2=> $value2
}
);
mysqli_close($con);
?>

It's as simple as just adding elements to the array:
//Setup blank array
$example = array();
//Create a loop, for example purposes.
foreach(range(0, 99) as $i){
//Create random variable that we'll add to our array
$randVar = mt_rand(1, 90000);
//$i will be our array key/index
$example[$i] = randVar;
}
//var_dump the array so you can see the structure / end result
var_dump($example);
You could also create it like so:
//Create random array key/index
$myRandKey = mt_rand(1, 90000);
//Create random variable value.
$myRandVar = mt_rand(1, 90000);
//Setup an array
$example = array(
$myRandKey => $myRandVar
);
//Another array key that we'll add to our array
$secondKey = 'test';
//Add it
$example[$secondKey] = 'This is just an example!';
//Dump out the array
var_dump($example);
array_push will also work (using mysql_fetch_assoc, like in your example):
$example = array();
while($row = mysql_fetch_assoc($result)){
array_push($example, $row);
}
var_dump($example);
In your particular example (since you added your code):
print_r($new_array[] = $row[]);
should be changed to:
print_r($new_array[] = $row);
In your code, I'd change it to:
$new_array = array();
while($row = mysqli_fetch_array($result)){
$new_array[] = $row;
}
Or, if you want to key your array by a unique column (Primary key, for example):
$new_array = array();
while($row = mysqli_fetch_array($result)){
$new_array[$row['id']] = $row;
}

Look, this is so easy, you just need to pay more attention to the answers you're getting here.
Here is the simplest way you can do it:
$to = array();
$to[] = array($send_to1 => $value1);
$to[] = array($send_to2 => $value2);
while ( $row = mysqli_fetch_array($result) ) {
$to[] = array($row['send_tox' => $row['valuex']);
}
You need to first understand how Arrays and Loops work in PHP, then try to make a dynamic array in a loop.

Actually you almost got it. It's lower A in 'array'
To initialize an empty array:
$to = array();
In your case (you already have some values), you can do:
$to = array(
$send_to1 => $value1,
$send_to2=> $value2
);
In either case, you can later add more elements doing
$to[$someOtherKey] = $someOtherValue;
