Php loop foreach behave strange and prints out wrong html - php

Question

I am trying to prepare email html and I have 2 groups of customers-
1 group just will receive email
2 group will receive same email + voucher inside..
I have prepared a short code just to illustrate the problem. Here it is:
$voucher='<div>VOUCHER IMAGE COMES HERE</div>';//only group for voucher must see it
$mail_description='Here comes my mail text';
$voucherarray=array("mail1#gmail.com","mail3#gmail.com");
$mailaray=array("mail1#gmail.com","mail2#gmail.com");
$html='';
foreach($mailaray as $email){
$html.='<div>'.$mail_description.'</div>';
if(in_array($email, $voucherarray)){
$html.=$voucher;
echo $email.'is for voucher';
}else{ $email.'is not for voucher';}
$html.='<table><tr><td>here is some other text</td></tr></table>
<div clss="footer"></div>';
mail($email,'subject',$html);
}
echo $html.'<br />';
this code prints out:
mail1#gmail.comis for voucher
Here comes my mail text
VOUCHER IMAGE COMES HERE
Here comes my mail text
here is some other text
Here comes my mail text
VOUCHER IMAGE COMES HERE
Here comes my mail text
here is some other text
What is wrong with it and why it prints out VOUCHER IMAGE COMES HERE for both mails as only one is for voucher?
Also it sends same mail to all groups users

Answer 1

Your need to separate between the html you send in the mail and the output you want to see for the job that sends the mail. second thing you need to empty the mail body variable after each iteration, you don't want every client to receive the mail content of the previous clients.
$voucher='<div>VOUCHER IMAGE COMES HERE</div>';//only group for voucher must see it
$mail_description='Here comes my mail text';
$voucherarray=array("mail1#gmail.com","mail3#gmail.com");
$mailaray=array("mail1#gmail.com","mail2#gmail.com");
$html='';
foreach($mailaray as $email){
$mailHtml = '';
$mailHtml.='<div>'.$mail_description.'</div>';
if(in_array($email, $voucherarray)){
$mailHtml.=$voucher;
echo $email.'is for voucher<br>';
}else{
echo $email.'is not for voucher<br>';
}
$mailHtml.='<table><tr><td>here is some other text</td></tr></table><div clss="footer"></div>';
mail($email,'subject',$mailHtml);
$html .= '<br>' . $mailHtml;
}
echo $html.'<br />';
