I have a date range selected from the Database. For this particular example the date is between the 20th June - 29th June.

I have managed to create an array of those dates, However the date is repeated numerous times.

My array looks like this :

Array
(
 [0] => 2013-06-20
 [1] => 2013-06-20
 [2] => 2013-06-20

)

As you can see from the array, There are 89 instances. Yet this is for only 9 days?

I have a feeling it has something to do with my for loop.

My PHP code is as follows :

$user_availabilty = $this->vendor_model->get_user_availability($this->get_user_id());

        if($user_availabilty)
        {
            foreach($user_availabilty as $user_avail)
            {
                $start = strtotime($user_avail->user_availablity_startdate);
                $end = strtotime($user_avail->user_availablity_enddate);

                $times = array();

                for ($i = $start; $i <= $end; $i += 24 * 3600)
                {
                    for ($j = 9; $j <= 17; $j++)
                    {
                        $times []= date("Y-m-d", $i);
                    }
                }
            }

How do I get just the 9 instances into my array, rather than 89?

array_uniqueで試してください

$times = array_unique($times);

次の行の目的は何ですか?

for ($j = 9; $j <= 17; $j++)

必要なものを取得するには、この行にコメントするだけでよいと思います。

// for ($j = 9; $j <= 17; $j++)

機能を使用してくださいarray_unique。

PHPマニュアルから直接の例。

<?php
  $input = array("a" => "green", "red", "b" => "green", "blue", "red");
  $result = array_unique($input);
  print_r($result);
?>

出力は次のようになります。

Array
(
    [a] => green
    [0] => red
    [1] => blue
)

配列がすべてのユーザーに対して「日」の日付の複数のインスタンスを生成しているため (9 人のユーザーがいます!)、日付範囲を生成するためにユーザーリストをプルする必要はありません。

ユーザープルなしで以下のコードを使用して日付範囲を生成し、比較/チェックのためにこの配列を個別に渡してユーザープルを実行できます。

$start = strtotime($user_avail->user_availablity_startdate);
        $end = strtotime($user_avail->user_availablity_enddate);

        $times = array();

        for ($i = $start; $i <= $end; $i += 24 * 3600)
        {
            for ($j = 9; $j <= 17; $j++)
            {
                $times []= date("Y-m-d", $i);
            }
        }

他の回答で示唆されているように、 array_unique() を使用して修正できますが、ロジックフロー全体を見て、開始日と終了日を生成するためにループ内のループは必要ありません。mysql データベース内の使用可能なユーザーから最小/最大範囲を取得している場合は、それほど問題はありません (MIN() MAX() および DISTINCT を調べてください)。

これを使って

$user_availabilty = $this->vendor_model->get_user_availability($this->get_user_id());

        if($user_availabilty)
        {
            foreach($user_availabilty as $user_avail)
            {
                $start = strtotime($user_avail->user_availablity_startdate);
                $end = strtotime($user_avail->user_availablity_enddate);

                $times = array();

                for ($i = $start; $i <= $end; $i += 24 * 3600)
                {
                    for ($j = 9; $j <= 17; $j++)
                    {
                          if (!in_array(date("Y-m-d", $i),$times)){

                            $times []= date("Y-m-d", $i);
                              }

                    }
                }
            }

これにより、データがその配列に既に存在することを確認し、存在しない場合は配列に追加されます
