I have a for each loop that loops through a set of dates. How can I get the max value of $key_date
?
$i=0;
foreach ($data as $key_date => $value_price)
{
if($key_date>=$start_date && $key_date<=$end_date)
{
if (empty($temp[$i])) {
$temp[$i]=array($key_date(float)$value_price['price']);
}
else {
array_push($temp[$i], (float)$value_price['price']);
}
$i++;
}
}
Right now i get all the key_dates and value_prices based on the start and end date.How can I get only the price based on the latest date (max date). So instead of doing
array_push($temp[$i], (float)$value_price['settlement_price']);
I should be able to do array_push latest date between the $start_date and $end_date and its correspnding price

To get the maximum key in an array you can use:
$max_key = max(array_keys($array));
You can look here for more details:
