php pagination should start from 1 not 0 - php

Question

This is my function to download and paginate data from xml file.
<?php
function get_feed_posts($link) {
if(!isset($_GET['page'])) {
$_GET['page'] = 0;
}
$startPage = $_GET['page'];
$perPage = 13;
$currentRecord = 0;
$xml = new SimpleXMLElement($link, 0, true);
foreach($xml->results->result as $item) {
$currentRecord += 1;
if($currentRecord > ($startPage * $perPage) && $currentRecord < ($startPage * $perPage + $perPage)) {
?>
<li><a class="go-to" href="<?php echo $item->click_url;?>" title="<?php echo $item->name;?>">Go to store</a></li>
<?php
}
}
for ($i = 0; $i <= ($currentRecord / $perPage); $i++) {
$n=$i+1;
echo("<a href='?page=".$n."'>".$n."</a>");
}
} ?>
This code works great. But I want to have my pages starting from ?page=1, now this code starts from ?page=0

Answer 1

What about this?
<?php
function get_feed_posts($link) {
if(!isset($_GET['page'])) {
$_GET['page'] = 1; // changed this line
}
$startPage = ($_GET['page'] < 1) ? 0 : $_GET['page'] - 1; // changed this line
$perPage = 13;
$currentRecord = 0;
$xml = new SimpleXMLElement($link, 0, true);
foreach($xml->results->result as $item) {
$currentRecord += 1;
if($currentRecord > ($startPage * $perPage) && $currentRecord < ($startPage * $perPage + $perPage)) {
?>
<li><a class="go-to" href="<?php echo $item->click_url;?>" title="<?php echo $item->name;?>">Go to store</a></li>
<?php
}
}
for ($i = 0; $i <= ($currentRecord / $perPage); $i++) {
$n=$i+1;
echo("<a href='?page=".$n."'>".$n."</a>");
}
} ?>
Notice that any x in ?page=x smaller than 1 will be treated as 0, but you could do better (throw an error? redirect to ?page=1?).
