Php属于特定季度

Question

I'm sorry i'm currently having a problem on this section. My Date format is Y-m-d

$date1 = '2016-03-1';
$date2 = '2016-07-1';
$date3 = '2016-10-1';
$date4 = '2016-12-1';

if today is 2016-8-12 it should fall at $date3 since it the next period. i tried using the if conditions but it only falls at first condition. Can you enlighten me on this?

My code is somewhat like this

$today = date("2016-07-29");
if(strtotime($date1) < strtotime($today)){
        $next_accrual_date = $date1;
        $date_condition = 'condition 1';
    }else
    if(strtotime($date2) <   strtotime($today)){
        $next_accrual_date = $date2;
        $date_condition = 'condition 2';
    }else
    if(strtotime($date3) <  strtotime($today)){
        $next_accrual_date = $date3;
        $date_condition = 'condition 3';
    }else
    if(strtotime($date4) <  strtotime($today)){
        $next_accrual_date = $date4;
        $date_condition = 'condition 4';
    }
echo $next_accrual_date." falls to ".$date_condition;

One way to do this is

<?php
$dates = array();
$dates[] = '2016-03-1';
$dates[] = '2016-07-1';
$dates[] = '2016-10-1';
$dates[] = '2016-12-1';

usort($dates, "cmp");

function cmp($a, $b){ 
    return strcmp($a, $b); 
}

foreach($dates as $date){
  if($date > "2016-08-12"){
    echo $date;
    break;
  } 
}

//print_r($dates);

?>
