Which array function?

[deko]

I have a file containing only UNIX timestamps that I pull into an array with
file($myarray)

1157950336
1157950334
1157949470
1157948606
1157947742
1157946878
1157946014

I need to get a count of timestamps that fall between specific times - those
that are less than 24-hours old, those that are between 24-hours old and 30-days
old, and so forth.

I thought about using array_filter and a function like this:

function getlast24h($vis its24h)
{
return ($visits24h TIMEAGO24H);
}

$last24h_array = array_filter($m yarray, "getlast24h ");

where TIMEAGO24H is a constant representing a timestamp of time() - 24hours

but then I cannot get any additional time segments (such as last 30days, last 3
months, etc) - since $myarray will have had those timestamps filtered out.

I need to start with the smallest section (24-hours) rather than the largest,
otherwise I could filter downward.

Is there a function that will do this? Any examples would be helpful...

Thanks in advance.

array_filter() doesn't modify its argument, since it is passed by value
not reference. Therefore $myarray won't have the timestamps removed, and
can be used again.

Re: Which array function?

Pass the array to a function

set a variable = to now - 24hrs.

Loop through the array and either build a new array of the values or
add one to a counter if the value falls in the required range

return either the counter or the new array.

This way you will not destroy the original array.

Thanks, that helped. Seems like these functions want constants. I was had
trouble with a variable.

Here's what I ended up with:

function getbaz_current( $var)
{
return ($var <= MAXDAILY);
}

function getbaz_new($var )
{
return ($var < TIMEAGO30D && $var >= MAXDAILY);
}

$baz_current = array_filter($c ounter_array, "getbaz_current ");
$baz_new = array_filter($c ounter_array, "getbaz_new ");
