PHP выбор оператора из MySql в Excel. Форматирование даты в ГГГГММДД

Question

Примечание: в базе данных MySql "dob" - это varchar, и в этом формате: мм / дд / гггг

Дата рождения, Дата вступления в силу Cvrg и Дата истечения срока действия Cvrg должны быть изменены с мм / дд / гггг на ггггммдд, когда они поступают в Excel. Пожалуйста, смотрите код ниже:

Answer 1

Учитывая дату в определенном формате, обычно вы можете просто выполнить быстрое преобразование, используя date и strtotime следующим образом:

// convert old date string to YYYYmmdd format
$date = date('Ymd', strtotime($old_date_string));

Answer 2

вы можете использовать функцию mysql date_format вроде

DATE_FORMAT(dob,'%Y%m%d') AS 'Date of Birth',

дает 20100118 на сегодня

edit: поскольку dob is varchar, вы должны проверить его в foreach и просто использоватьстроковые функции или ответ cballou будет работать для вас

foreach ( $row as $key => $value )
   {
    if ( ( !isset($value) ) OR ( $value == "" ) )
    {
     $value = "\t";
    } 
    else 
    {
 if($key == 'Date of Birth') {
    $exploded_value = explode("/",$value);
    $value = $value[2].$value[0].$value[1];
    // or according to cballou's answer
    //$value = date('Ymd',strtotime($value));
 }
     $value = str_replace('"', '""', $value);
    $value = '="' . $value . '"' . "\t";
 //        ^
 //        Added an equal sign
    }
    $line .= $value;
   }
