Re: [chiPHPug-discuss] A PHP Array question

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.

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];
}

And yes, that is a bastardized way of doing it, but I've tried to move away
from associative arrays and more into classes lately
