从MYSQL查询到Google图表

Question

Let me start by saying, i'm not sure how to ask the right question on this, but here goes...

I have a database of amounts that all have times attached to them. for example four rows would look like:

2  | 1000 | 2012-11-01 12:09:09
2  | 800  | 2012-11-01 12:10:21
10 | 900  | 2012-11-01 12:11:36
10 | 750  | 2012-11-01 12:12:46

The first column is the user. I am wanting to out put this to a google line graph, but really struggling on how to set-up the query.

The end result in the javascript array needs to looks like:

data.addColumn('string', 'Date');
data.addColumn('number', 'User 2');
data.addColumn('number', 'User 10');

data.addRows([
    ['12:09', 1000, null],
    ['12:10', 800, null],
    ['12:11', 800, 900],
    ['12:12', 800, 750]
]);

Any help or steers more than welcome on this. I'm thinking a few php loop, but a little stuck...

Put this at top of Your document:

<?php

$dsn = 'mysql:dbname=myDbName;host=127.0.0.1';
$user = 'dbUserName';
$password = 'dbPassword';

$pdo = new PDO($dsn, $user, $name);

$result = $pdo->query('select * from YourAmountsTableName');
foreach ($result as $row) {

$rows[] = "['{$row['time']}',{$row['ammount']},{$row['yourThirdValue']}]";

}
$rowsString = implode(',',$rows);
?>

Now In Your HTML document, or Your Javascript, echo the $rowsString in the place for rows:

data.addRows([<?php echo $rowsString; ?>]);

adjust the code given for names, passwords ect. I have not tested the code, so please check if no quotes are missing or other misspellings. As for the Google Chart, https://developers.google.com/chart/interactive/docs/examples?hl=pl have great examples
