PHP: Email Parsing - Multiple Recipients - php

Question

I am piping email that get's sent to my server to a PHP script. The script parses the email so I can assign variables.
My problem is once in awhile somebody will include my email address to an email that's getting sent to multiple recipients and my script will only get the first one. I need it to find my email address then assign it to a variable.
Here is what the email array looks like: http://pastebin.com/0gdQsBYd
Using the example above I would need to get the 4th recipient: my_user_email#mydomain.com
Here is the code I am using to get the "To -> name" and "To -> address"
# Get the name and email of the recipient
$toName = $results['To'][0]['name'];
$toEmail = $results['To'][0]['address'];
I assume I need to do a foreach($results['To'] as $to) then a preg_match but I am not good with regular expressions to find the email I want.
Some help is appreciated. Thank you.

Answer 1

Instead of usin preg_match inside foreach loop you can use strstr like below
Supposing you are looking for my_user_email#mydomain.com use following code
foreach($results['To'] as $to)
{
// gets value occuring before the #, if you change the 3 rd parameter to false returns domain name
$user = strstr($to, '#', true) ;
if($user == 'my_user_email')
{
//your action code goes here
}
}
example:
<?php
$email = 'name#example.com';
$domain = strstr($email, '#');
echo $domain; // prints #example.com
$user = strstr($email, '#', true); // As of PHP 5.3.0
echo $user; // prints name
?>

Actually, you do not need to use a regexp at all. Instead you can use a PHP for statement that loops through your array of To addresses.
$count = count($root['To']);
for ($i=0; $i < $count; $i++) {
//Do something with your To array here using $root['To'][$i]['address']
}
