php code to send email using find function in forloop - php

Question

I have startdate and end date in my table like below.
startdate = 2016-01-01
Enddate = 2016-06-20
Now i want to send email automatically before 1 month from end date.
everything is working fine...email is also sending..
But my problem is i want to send email to multiple users if there are 2 rows match in table with my conditions then email is gone to both the users.
But my code only send email to only single users..not all users.
I want email is gone to all users one by one.
public function certificateExpired()
{
$this->autoRender = False;
$this->loadModel('Certificate');
$data = $this->Certificate->find("all", array(
'recursive' => -1, // should be used with joins
'fields' => array('User.*', 'Certificate.*'),
'joins' => array(
array(
'table' => 'users',
'alias' => 'User',
'type' => 'LEFT',
'conditions' => array('User.id = Certificate.user_id')
)
),
'conditions' => array('Certificate.is_expirable' => 1,'Certificate.status' => 1)
));
foreach ($data as $row) {
$currentdate = date("Y-m-d");
$date = $row['Certificate']['end_date'];
$newdate = strtotime($date .' -1 months');
$enddate = date('Y-m-d', $newdate);
if ($currentdate >= $enddate) {
//For sending email
$data['email'] = $row['User']['email'];
$data['name'] = $row['User']['name'];
$data['document_name'] = $row['Certificate']['name'];
$data['templateid'] = 19;
$send_mail = $this->EmailFunctions->certificateExpiredTemplate($data);
if ($send_mail) {
$this->redirect(array('controller' => 'Dashboards', 'action' => 'shipperDashboard'));
}
}
}
}

foreach ($data as $row) {
$currentdate = date("Y-m-d");
$date = $row['Certificate']['end_date'];
$newdate = strtotime($date .' -1 months');
$enddate = date('Y-m-d', $newdate);
if ($currentdate >= $enddate) {
//For sending email
$data['email'] = $row['User']['email'];
$data['name'] = $row['User']['name'];
$data['document_name'] = $row['Certificate']['name'];
$data['templateid'] = 19;
$send_mail = $this->EmailFunctions->certificateExpiredTemplate($data);
}
}
$this->redirect(array('controller' => 'Dashboards', 'action' => 'shipperDashboard'));
Change the foreach loop as above.
