Arrays and loops through days - php

Question

I have a problem creating this function. My code is a mess and I'm stuck, so I'd rather not post it. I'd rather ask for a fresh solution.
I have an array (mysql rows), fetched with today's date as a condition. I want to create a new array based on data from the previous array and insert it into the database also by today's date. Limit is 15. So if there are already 10 rows by this date, insert only 5, and continue on the next date, for as long as there are rows from the first array.
I am using php and code igniter.

Answer 1

I don't know how you're fetching the data or how you are generating new data, but something like this;
//loop through days that you want to check/update
//fetch existing data for this day into $data
if( count( $data ) >= 15 ) continue; //skip days that already have 15+
for( $x = 0; $x < 15 - count( $data ); $x++ )
{
//insert one new row here
}
//end days loop

Here is how i did it and it does what i want it to do. Not sure if it is the best way to achieve this functionality. Here i was using a temporary array just for testing. Each element will be a new row for the database. Used 3 as maximum(instead of 15) for testing only.
$subscriptions = Subscription::all(array('conditions' => 'token != "" ', 'order' => 'id asc'));
$startTime = strtotime('2013-08-15');
$temparray = array();
$projects = Project::all(array('conditions' => 'end = "'.date("Y-m-d", $startTime).'" '));
if ($projects){$counter = count($projects);}else{$counter = 0;}
while (list($key, $value) = each($subscriptions))
{
if ($counter == 3)
{
do
{
$startTime = strtotime('+1 day', $startTime);
$projects = Project::all(array('conditions' => 'end = "'.date("Y-m-d", $startTime).'" '));
if (count($projects) < 3)
{
$counter = count($projects);
break;
}
} while ($counter <= 3);
$temparray[] = $value->date . " " . date("Y-m-d", $startTime);
continue;
}
$temparray[] = $value->date . " " . date("Y-m-d", $startTime);
$counter++;
}
