Hey there, PHP-folks! I have an array question, and I was hoping someone here could point me in the right direction. So I¹ve got this array, see... $arToday[0][³title²] = ³Patty Duke² $arToday[0][³starttime²] = 12:00:00 $arToday[1][³title²] = ³Sesame Street² $arToday[1][³starttime²] = 12:30:00 ... ... Etc. Is there an easy way for me to ³query² this array to snag the index of the record whose starttime variable is current? Thereby selecting the name of the program that may be airing ³now²? Thanks so much for your help! If there¹s some other list I should be posting questions to instead of this one, let me know. Steve |

off the top of my head, I dont know of any other way than traversing the
array.. something like:
$aln=count($arToday);
$rec=0;
$found=0;
$title='';
$currenttime=[however you want to construct this];
while($rec<$aln){
if( $arToday[$rec]['starttime']==$currenttime ){
$found=$rec;
$title=$arToday[$rec]['title'];
$rec=$aln; // skip rest of loop
}
$rec++;
}
that was just typed without testing, so beware typos ;-)..
there _may be_ some better multi-dimensional array index function built
in to PHP but it would, in essence do the same as above..

Thanks, Jason.
If traversing the array is the best way to go, then I suppose that'll be
fine. I appreciate the code example!

If you really want it on one line, you could use a regex on print_r with output set to true. Otherwise, I'd suggest creating a Record class and using that. 2008/11/14 Steve Gadlin <sg...@wc...> > Hey there, PHP-folks! > > I have an array question, and I was hoping someone here could point me in > the right direction. > > So I¹ve got this array, see... > > $arToday[0][³title²] = ³Patty Duke² > $arToday[0][³starttime²] = 12:00:00 > $arToday[1][³title²] = ³Sesame Street² > $arToday[1][³starttime²] = 12:30:00 > ... > ... > Etc. > > Is there an easy way for me to ³query² this array to snag the index of the > record whose starttime variable is current?

ok, here's how i'd do it in practice:
Assuming the < and > operators work on the timestamp given
for($c = count($arToday)-1; $c >= 0; $c--){
if($arToday[$c]['starttime'] < $time) return $c
}

And change my < to a <=
I guess thsi just shows I should proofread my stuff before I post it here.
The reason I assume < and > operators work on the timestamp is because if
times are shown like so:
04:30:15
Then string comparison will work
if it's
4:30:15, then it won't.

If you reorganized the array into something like this:
$arToday['titles'][0] = 'Patty Duke'
$arToday['titles'][1] = 'Sesame Street'
$arToday['starttime'][0] = 12:00:00
$arToday['starttime'][1] = 12:30:00
You can just look through the starttimes without having to worry about the titles. When you find a starttime that you need, just pull up the title with the same index. Here's some pseudocode to demonstrate.
$count = count($arToday['starttime']);
$interesting_time;
for($i = 0; $i < $count; $i++)
{
//Do whatever test you want to on $arToday['starttime'][$i] to determine if it's the right time.
...
//If the current start time is a time you're interested in, take note of this. (You'll probably do this in a conditional.)
$interesting_time = $i;
//Or, if you want to keep note of multiple times. (Say, if more than one show is on at the same time.)
$interesting_time[] = $i
}
//If you picked one time:
echo $arToday['title'][$interesting_time];
//If you picked multiple times:
foreach($interesting_time as $value)
{
echo $arToday['title'][$value];
}

Or if it is imperative that the array have the same structure it has now...
$arToday[0]['title'] = 'Patty Duke';
$arToday[0]['starttime'] = 12:00:00;
$arToday[1]['title'] = 'Sesame Street';
$arToday[1]['starttime'] = 12:30:00;
$count = count($arToday);
$interesting_time;
for($i = 0; $i < $count; $i++)
{
//Test $arToday[$i]['starttime'] to see if it's important.
...
//Picking out the interesting indexes is the same as last time.
//If you only want one time:
$interesting_time = $i;
//Or for multiple times:
$interesting_time[] =$i;
}
//Single.
echo $arToday[$interesting_time]['title'];
//Multiple.
foreach($interesting_time as $value)
{
echo $arToday[$value]['title];
}
No matter which way you choose to construct your array, keep in mind that you will have to handle $interesting_time differently depending on whether you want a single interesting time or multiple times. foreach() will fail if the variable you pass it isn't an array, and it is a little sloppy to make an array containing a single value via the $foo[] = 'bar' method.

And yes, that is a bastardized way of doing it, but I've tried to move away

Just catching up on email and... First off, it really should be in a database that you search and sort. Using PHP to do that is almost always a sign of a bad architectural decision... You might even toss the data into sqlite just to have sane way to search/sort it. That said, if the array is "small" iterating through is fine But if the array is big, you could probably use some kind of http://php.net/usort on the array and then a binary search on the time frame in question to find the answer quicker than an iteration.
