Insert date check into function - php

Question

I have this function that loads an array from a table called 'customer' it works fine, but I also want it to check if the customer has expired and if so display an error
So I have code below that to check if the id_expiry_date is over, but I'm having difficulty working out where to put it in the function. Tried a few things, but just seems to break. Please assist.
function customer_load_by_id($id)
{
$dbh = dbh_get();
$id = array();
$sql = 'select c.* ' .
'from customer c ' .
'where c.cust_id = (select max(cust_id) from customer where id = ?)';
$stmt = $dbh->prepare($sql);
$stmt->execute(array($id));
$r = $stmt->fetch();
if (!is_bool($r)) {
$fields = id_get_fields();
foreach ($fields as $field) {
$n = $field['name'];
$id[$n] = $r[$n];
}
}
dbh_free($dbh);
$exp_date = "$id_expiry_date";
$todays_date = date("Y-m-d");
$today = strtotime($todays_date);
$expiration_date = strtotime($exp_date);
if ($expiration_date > $today) {
//continue happily
} else
{
//don't continue
}
return $id;
}
// One of the fields in the array above is id_expiry_date

I do not really get how you SQL schema is but, using Pomm, I would write the following code:
<?php
use PommProject\Foundation\Pomm;
$loader = require __DIR__ . '/vendor/autoload.php'; //<- setup autoloading
$pomm = new Pomm(…); // <- connection params go there
$sql = <<<"SQL"
select
c.*,
c.expiry_date < now() as is_expired
from customer c
where c.cust_id = (select max(cust_id) from customer where id = $*)
SQL;
$result = $pomm
->getDefaultSession()
->getQueryManager()
->query($sql, [$id])
->current() // <- Take the first row if exist
;
if ($result) {
if ($result['is_expired']) { //<- 'is_expired' is converted as boolean
echo "expired";
} else {
echo "not expired";
}
} else {
echo "no result";
}
