  $result = mysql_query($query) or die('cannot get results!');
  while($row = mysql_fetch_assoc($result)) {
  		$events[$row['event_date']][] = $row;
}

 

Hi. I'm brand new to PHP and I don't quite understand what the line

$events[$row['event_date']][] = $row;

does.

 

Thanks a lot.

The bracket notation refers to arrays

http://php.net/manual/en/language.types.array.php

 

Here's some example code

<?php

$array['test'][0] = 'foobar';

$key = 'test';

echo $array[$key][0];
// Outputs foobar

// Adds a new entry on to the end of the array
$array[$key][] = 'kasbah';

print_r($array);
/* Outputs
Array
(
    [test] => Array
        (
            [0] => foobar
            [1] => kasbah
        )

)
*/
?>

... I don't quite understand what the line

$events[$row['event_date']][] = $row;

does.

 

Specifically, it creates an events array where the key is the event date and the value is another array containing the event data eg

Array
(
    [2012-06-16] => Array
        (
            [event_id] => 1
            [event_date] => 2012-06-16
            [event] => Rock Festival
            [venue] => Chester
        )

    [2012-06-23] => Array
        (
            [event_id] => 2
            [event_date] => 2012-06-23
            [event] => Beerfest
            [venue] => Stoke-on-Trent
        )

)
