August 8, 2017Large Loops
I would strongly advise against sending 20K emails yourself, you are bound to hit the limite pretty soon and it will just crush your domain name's email deliverability, sending everything to people's junk mail folders. When your spam score becomes problematic it can be extremely difficult to bring it back to an acceptable level. You should rather use some hosted service like mailgun , where the 20k emails will cost you about 5$. It is not free but really there is no magic trick to send this kind of volume reliably. Keeping mailgun as an example, you can send up to 1K messages per API call, so you should slice your addresses array into chunks of 1000 so you would only have a 20 occurrence loop, which shouldn't take too much time.

In PHP you define/declare an array by just
$oldSchool = array();
$newSchool = []; // use this one!
You can add new elements to it by simply using [] next to the array as:
$array[] = 'new element';
count($array); // returns the lenght of the array
You can easily iterate an array using a foreach loop:
foreach($array as $key => $value) {
echo sprintf('key: %s, value: %s',$key, $value) . PHP_EOL;
}

PHP doesn't have a concept of arrays. It has ordered maps which it calls arrays. They have no finite size. You can't have a fixed size array unless you use the SplFixedArray class
To create PHP's "array" you can use the following syntax.
$myArray = [];
To add elements you use keys. This will map one value to another.
$myArray['myKey'] = 'My string';
You can also use numerical keys or append a new value to the map.
$myArray[42] = 'My string of 42';
$myArray[] = 'Appended value'; // the key will be generated by PHP and will be the next available numerical value
