Multiple records with GET and PDO - php

Question

Trying to figure out how to do this on multiple records. I am trying things out, looking at reference but not understanding how to get it working, firstly here Here is my code that works:
My href link in loop.
city
My PHP
if (isset($_GET['city'])) {
$city = $_GET['city'];
$stmt = $db->prepare("SELECT * from table WHERE city = ? ");
$stmt->execute(array($city));
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) : //loop starts
} else { //html content }
The above simply pulls city records that are being called via a URL variable in my first loop. What If wanted to repeat this multiple times with different URL Variables to generate different results from the database. So instead of just getting one record like my above code I want to get 2 more, here is a below example of what I mean.
Example Href links in a loop with the URL variables city, name country:
city
name
country
Example of PHP which is not working, but getting these URL variables and passing them through to mysql by SELECT, hopefully you get what I mean):
if (isset($_GET['city'], $_GET['name'], $_GET['country'])) {
$city = $_GET['city'];
$name = $_GET['name'];
$country = $_GET['country'];
$stmt = $db->prepare("SELECT * from table WHERE city = ? OR name = ? OR country = ?");
$stmt->execute(array($city, $name, $country));
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) : //loop starts
} else { //html content }
Any advice on how to achieve this would be appreciated, also if there is an easier way to do this or my current code is not up to scratch, please let me know. Thanks!

Answer 1

if (isset($_GET['city'])||isset($_GET['name'])||isset($_GET['country'])) {
echo $city= $_GET['city'];
echo $name=$_GET['name'];
echo $country $_GET['country'];
}

I think you're looking to put the url's into an array so that you can use them later? If so, you could do something like this:
if (isset($_GET['city'], $_GET['name'], $_GET['country'])) {
$city = $_GET['city'];
$name = $_GET['name'];
$country = $_GET['country'];
//added:
$url_array = array();
$stmt = $db->prepare("SELECT * from table WHERE city = ? OR name = ? OR country = ?");
$stmt->execute(array($city, $name, $country));
//$row changed to $rows
while($rows = $stmt->fetch(PDO::FETCH_ASSOC)) : //loop starts
//foreach added
foreach($rows as $row){
$url_array[] = $row;
}
} else { //html content }
I hope that helps?
