Question

i have an array of data from from my database, it looks like this

[0] => Array
    (
        [id] => 40
        [market] => EUR/USD
        [date] => 2012-02-29 12:20:34
        [points] => 42
    )

[1] => Array
    (
        [id] => 41
        [market] => EUR/USD
        [date] => 2012-02-29 13:23:03
        [points] => 11
    )

and it goes on like this till the end of the database query which is something like 200 records. The database has information for a whole month with multiple records for the same day.

Anyway i want to be able to go through the array and take out all the information for a single day (By the why the information coming from the database is already sorted DESC).

How would i do this? I’ve looked at “array_splice” and “array_file” but i’m struggling to put them into this problem.

Thanks.

You can do something like

$output = array();
foreach ($input as $row) {
    $date = substr($row['date'], 0, 10);
    if(!isset($output[$date])) {
        $output[$date] = array();
    }
    $output[$date][] = $row;
}
print_r($output);
