Hi, TR Shaw
I would next try curl as php-extension.
If that is working well, and you need it definitely with file() I'd use
Wireshark to check which request is sent to the remote machine.

That's a good idea, but
date('d',strtotime('last day of this month'));
gives me the number of days in *this* month, but not the next, or previous,
month.
I need the result to be whatever date was selected -- something like:
$number_days = date('d',strtotime('last day of April, 2014'));
But that doesn't work.
Sure it does, though you may have some issues when using
punctuation, unnecessary words, or using capital letters for anything
other than proper names. What version of PHP are you using? I get
the correct answers for all of the following phrases:
"last day of April 2014"
"last day of this month"
"last day of next month"
"last day of last month"
"third Saturday March 2012"
Or you can even be excruciatingly redundant:
echo date('d',strtotime('last day of this
month',strtotime('next month')));
echo date('d',strtotime('last day of this
month',strtotime('February 2018')));
echo date('d',strtotime('second Monday',strtotime('September 2012')));
I must admit I'm still at a loss why people would want a function to
tell them the amount of days in a month. That amount is pretty much
fixed (except for february, but that's also mathematically easy to fix).
So a simple function like:
function getAmountOfDaysInAMonth($month, $year) {
$days = array(31, (($year%4==0 and ($year%100 > 0 or $year%400==0))
? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
return $days[$month+1];
}
Would work just fine. Unless of course you want to count the amount of
days during the changing of calendars (ie during the change of the
julian calendar to the gregorian), or in different calendars altogether.
Why (ab)use the datetime library for such a very simple thing? In the
last case, I would indeed use DateTime, simply because it's not an easy
answer.

Good question, but I think the problem here is that there are tons of these small functions, and you got to make a choice on what to implement and what not.

[PHP] looking for an array sorting function.. just not sure which one.. and how yet
Hi Everyone
I am newbie enough with the terminology around PHP arrays that I am slow to
wrap my head around what I know is in the docs (what i am reading)... but just
can't identify yet.
I think it will be faster if someone can translate for me in terms of my
question:
I make an array by building up its members form the results of a db call, like
so:
foreach ($query->result() as $row) {
$arr_cTree[$row->cID] = array($row->cPcID, $row->cL, $row->cName,
$row->cSeg, $row->cSort);
}
I have that array's members' values displaying on an HTML page fine by making
recursive function calls to grab the children of each parent member found..
but the order those array members are displayed on the page is not what I want
(it seems to be displaying according to the order the rows are found in the
db). To remedy, I want to sort on the last value in the array which is the
value of each array member. (If I said that right.) IOW, I want to sort my
$arr_cTree array by the decimal values stored in $row->cSort ($arr_cTree[[4]),
before I then display on the page.
Can someone point me to the array sorting function you think is suited to this
job.. and perhaps give me an example in pseudo code if that helps make it more
clear in this case.
Thanks!

The best option is to sort it in the query. But if for whatever reason
you sort it in the query for use one way and then need it sorted
differently later, then most likely execute another query with the new
sorting. If having tried that, and that's not what works, then use
array_multisort(). Pay attention to example #3 on php.net as this is
what you want.

Actually, you may construct your array as follows to make sorting with
ksort():
foreach ($query->result() as $row) {
$arr_cTree[$row->cSort] = array[$row->cID, $row->cPcID, $row->cL,
$row->cName, $row->cSeg, $row->cSort);
}
However you do it, look at constructing your array the way you need it
to easily sort, display etc.

I like that -- here's a small variation.
function numberDaysMonth($month, $year)
{
// Leap year is definded as a year that is evenly divisible by four
// AND (year NOT evenly divisible by 100 OR year IS evenly divisible by
400)
$feb = ($year%4 == 0 && ($year%100 != 0 || $year%400 == 0) ) ? 29 : 28;
$days = array(0, 31, $feb, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
return $days[$month];
}
