Foreach 循环从结果中剥离所有数据

Question

在下面的代码中，我创建了一个电子邮件黑名单，我想删除这些电子邮件，但是当我使用if(stripos($row->guestEmail, $b))运行时，我得到一个空数组

如果我删除stripos并使用基本的 if 语句运行if($row->guestEmail)它会显示所有数据，包括不在$blacklist中的电子邮件地址。

为什么每个黑名单都会剥离所有数据？

$guests = [];
$emails = [];
$blacklist = ['@booking.com', 'N/A', '[e-mail]', '[e-mail]'];
$date = date('Y-m-d');
foreach ($results->data as $row) {
$emails[] = $row->guestEmail;
foreach ($blacklist as $b) {
if (stripos($row->guestEmail, $b) !== false && date('Y-m-d', strtotime($row->endDate)) == $date) {
$guests[] = array(
'FirstName' => $row->guestFirstName,
'LastName' => $row->guestLastName,
'email' => $row->guestEmail,
'country' => $row->guestCountry,
'check-in_date' => $row->startDate,
'check-out_date' => $row->endDate,
);
}
}
}

Answer 1

$guests = [];
$emails = [];
$blacklist = ['@booking.com', 'N/A', '[e-mail]', '[e-mail]'];
$date = date('Y-m-d');
foreach ($results->data as $row) {
$emails[] = $row->guestEmail;
//check for all blacklist flags
$blackListed = false;
foreach ($blacklist as $b) {
if (stripos($row->guestEmail, $b) !== false) {
$blackListed = true;
break;
}
}
//if all pass and date is good, we're good
if (!$blackListed && date('Y-m-d', strtotime($row->endDate)) == $date) {
$guests[] = array(
'FirstName' => $row->guestFirstName,
'LastName' => $row->guestLastName,
'email' => $row->guestEmail,
'country' => $row->guestCountry,
'check-in_date' => $row->startDate,
'check-out_date' => $row->endDate,
);
}
}

Answer 2

试试这个：

$guests = [];
$emails = [];
$blacklist = ['@booking.com', 'N/A', '[e-mail]', '[e-mail]'];
$date = date('Y-m-d');
foreach ($results->data as $row) {
$emails[] = $row->guestEmail;
foreach ($blacklist as $b) {
if (stripos($row->guestEmail, $b) === false && date('Y-m-d', strtotime($row->endDate)) == $date) {
$guests[] = array(
'FirstName' => $row->guestFirstName,
'LastName' => $row->guestLastName,
'email' => $row->guestEmail,
'country' => $row->guestCountry,
'check-in_date' => $row->startDate,
'check-out_date' => $row->endDate,
);
}
}
}

问题出在

stripos($row->guestEmail, $b) !== false 

这种情况与您需要的相反。
