This is hideous, can anyone think of a more novel approach?
What I have is an array of values and timestamps:
17 15:31
16 15:32
27 15:33
14 15:34
11 15:35
now for a day I should have 1440 entries but there could be spotty
results, no data from say 11:59 -> 13:00.
What I need is to sum the values for each hour interval.
Because the results could be spotty I figured I would need to use a
lookup table so that I could zero out any empty hours (this is going
to be graphed)
So I have this:
loop through the set above and do
$hour = explode(":", $row[0]);
$comp[] = $hour[0] . "||" . $row[1];
$c00 = $c01 = $c02 = $c03 = $c04 .... = 0;
for ($a = 0; $a < sizeof($comp); ++ $a) {
list($h,$c) = explode("||", $comp[$a]);
switch ($h) {
case 00: $c00 += $c; break;
case 01: $c01+= $c; break;
case 02: $c02 += $c; break;
case 03: $c03 += $c; break;
case 04: $c04 += $c; break;
.....
}
}
Works but wow is it ugly..
Thoughts?

Where is the data coming from? I would presume an SQL database? If so, you
could use a group by with a substring to get the counts you need. MySQL happily
allows this to be done on date and datetime fields.

I am actually doing that already on the data coming in:
SELECT COUNT(signature) AS count,
SUBSTRING(CONVERT_TZ(timestamp,'+00:00','-03:00'),12,5) AS time..
as I am doing a minute breakdown as well. The query isn't cheap; about
half a second, so I was hoping to do my hourly consolidation in code
as I already have the data, instead of performing a second query.

I may be misinterpreting what you're asking, but what about something like
this:
$times = array(
17 => '15:31',
16 => '15:32',
27 => '15:33',
14 => '15:34',
11 => '15:35',
27 => '16:33',
14 => '17:34',
11 => '11:35',
11 => '11:36',
);
$sums = array_fill(0, 24, 0);
foreach ($times as $value => $time) {
$sums[substr($time, 0, 2)] += (integer)$value;
}
print_r($sums);
This produces:
/usr/bin/php /Volumes/Dev/Sites/playground/play4.php
Array
(
[0] => 0
[1] => 0
[2] => 0
[3] => 0
[4] => 0
[5] => 0
[6] => 0
[7] => 0
[8] => 0
[9] => 0
[10] => 0
[11] => 11
[12] => 0
[13] => 0
[14] => 0
[15] => 33
[16] => 27
[17] => 14
[18] => 0
[19] => 0
[20] => 0
[21] => 0
[22] => 0
[23] => 0
)
Process finished with exit code 0

The school I work with wants to set up PHP and MySQL hosting for about
10,000 students.
I see that in 5.4, PHP safe-mode is being removed. How is it supposed
to be done if not safe-mode?
Are all the hosting providers using suExec and running PHP as CGI or
FastCGI? If I'm trying to do this the right way, what way is that?
Anyone got link or pointers on what I need to learn?
