Unable to grab content traversing multiple pages

Question

I've written a script in php to scrape the titles and its links from a webpage. The webpage displays it's content traversing multiple pages. My below script can parse the titles and links from it's landing page.

How can I rectify my existing script to get data from multiple pages, as in upto 10 pages?

This is my attempt so far:

<?php
include "simple_html_dom.php";
$link = "https://stackoverflow.com/questions/tagged/web-scraping?page=2";
function get_content($url)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $htmlContent = curl_exec($ch);
    curl_close($ch);
    $dom = new simple_html_dom();
    $dom->load($htmlContent);
    foreach($dom->find('.question-summary') as $file){
        $itemTitle = $file->find('.question-hyperlink', 0)->innertext;
        $itemLink = $file->find('.question-hyperlink', 0)->href;
        echo "{$itemTitle},{$itemLink}<br>";
    }
}
get_content($link);
?>

The site increments it's pages like ?page=2,?page=3 e.t.c.

This is how I got success (coping with Nima's suggestion).

<?php
include "simple_html_dom.php";
$link = "https://stackoverflow.com/questions/tagged/web-scraping?page="; 

function get_content($url)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $htmlContent = curl_exec($ch);
        curl_close($ch);
        $dom = new simple_html_dom();
        $dom->load($htmlContent);
        foreach($dom->find('.question-summary') as $file){
            $itemTitle = $file->find('.question-hyperlink', 0)->innertext;
            $itemLink = $file->find('.question-hyperlink', 0)->href;
            echo "{$itemTitle},{$itemLink}<br>";
        }
    }
for($i = 1; $i<10; $i++){
        get_content($link.$i);
    }
?>
