Make PHP array from numerical data in MySQL table and multiply it - php

Question

Good day,
I'm a noob at PHP and MySQl. Looking to be pointed in the right direction.
I have a MySql table with 5 columns. Each column represents a specific set of data. All numerical.
I want to write PHP code which takes each value in a single column and puts it into an array that I can then modify.
I don't know how to get each column as a separate array. Should I get an array of all the rows and then do something extra to separate each of the 5 numbers in each row into 5 separate arrays?
**
require_once 'login.php';
echo $db;
$conn = mysqli_connect($hn,$un,$pw,$db);
if (!$conn) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
$query = "SELECT xox FROM tablex WHERE id = '1'";
$result = $conn->query($query);
if(!$result) die ("Database access failed: " . $conn->error);
$rows = mysqli_fetch_row($result);
while($rows){
echo $rows['index'];
}
echo $rows[0];
?>

Answer 1

$statement = **yourDatabaseConnection**->query('SELECT column1 FROM table');
$datas = $statement->fetch();
$datas will be an array of your column1 datas

Answer 2

Try reviewing the php documentation, here is a good place to start...php:mysql_fetch_row
Take a look at the example below, if is not what you looking for, please edit your question and provide the approach you are taking (your code) so that we have a better understanding where you are having issues.
<?php
$result = mysql_query("SELECT id,email FROM people WHERE id = '42'");
if (!$result) {
echo 'Could not run query: ' . mysql_error();
exit;
}
$row = mysql_fetch_row($result);
echo $row[0]; // 42
echo $row[1]; // the email value
?>
