PHP比较两个日期数组并检查匹配

已采纳

I want have two arrays with date objects which I want to compare. The first array contains todays date and the next five days:

$today = date('Y-m-d');
$fiveDays = [];
for($i=0; $i <= 5; $i++){
    $today = date('Y-m-d', strtotime('+1 day', strtotime($today)));
    $fiveDays[] = date('Y-m-d', strtotime($today));
}

which gives the result:

0: "2018-09-14"
1: "2018-09-15"
2: "2018-09-16"
3: "2018-09-17"
4: "2018-09-18"
5: "2018-09-19"

the other array can contain multiple objects:

[{
   days: (4) ["2018-09-13", "2018-09-14", "2018-09-15", "2018-09-16"]
   duration: 4
   end: "2018-09-16"
   name: "vacation blabla"
   start: "2018-09-13"
},
{
   days: (5) ["2018-09-20", "2018-09-21", "2018-09-22", "2018-09-23", "2018-09-24"]
   duration: 5
   end: "2018-09-24"
   name: "vacation blabla"
   start: "2018-09-20"
}]

Now I want to check if one of the days/dates of the first array will or is in the vacations_array. How can I achieve that?

EDIT

When a match is found, the second array(with the vacation-periods) where the match is true, must be assigned to a $vacation-array

    You can do it this way too:

    $result_array = array();
    $found = false;
    for($i=0; $i<count($vacation_array); $i++) {
      $found = false;
      for($j=0; $j<count($vacation_array[$i]['days']); $j++) {
        if(in_array($vacation_array[$i]['days'][$j], $array_1) && !$found) {
          $result_array[] = $vacation_array[$i];
          $found = true;
        }
      }
    }
    print_r($result_array);

    it's a bit simple but it may fit your needs:

    $event1 = ['days'=>["2018-09-13", "2018-09-14", "2018-09-15", "2018-09-16"]];
    $event2 = ['days'=>["2018-09-20", "2018-09-21", "2018-09-22", "2018-09-23", "2018-09-24"]];
    
    function checkEvents($ev1, $ev2){
        foreach($ev1 AS $day){
           if(in_array($day, $ev2)){
              return $day." is found in both events
    ";
           }
        }
        return "no match found
    ";
    }
    
    echo checkEvents($event1['days'], $event2['days']);

    use array_intersect()

    Basically you do this within a loop for array 2:

    $array_of_same_elements = array_intersect($array_1, $array_2[$i]['days']);
    

    $array_of_same_elements will now contain the dates you are looking for.

    A nice description of this is found here: https://www.w3schools.com/php/func_array_intersect.asp
