I would like to scrape the information of the product with PHP like description, title, price, quantity etc with a use of the url of the product in the amazon website or with the use on the ISBN.
How should I do it? Is there any example of code for me?
Thanks!

With PHP you can get the job done by opening the url with a file_get_contents() and by using a preg_match() with regex.
Then, taking a random article page and browsing its html code, for example https://www.amazon.com/Learning-PHP-MySQL-JavaScript-jQuery/dp/1491978910/
By inspecting the code we can see the price is in a specific <span>:
<span class="a-size-medium a-color-price header-price">
$35.00
</span>
Then we can do something like:
$link = 'https://www.amazon.com/Learning-PHP-MySQL-JavaScript-jQuery/dp/1491978910/';
$page_content = file_get_contents($link);
if(preg_match('/<span class=\"a-size-medium a-color-price header-price\">(.*?)<\/span>/i',
$page_content, $matches)) {
$price = trim($matches[1]);
} else {
echo "Price not found.";
$price = 0;
}
Then you have here enough basis to repeat the operation to get all the other informations you need to fetch.
Notice that it's not the best relevent way to do this as it assumes the HTML patterns are always the same from an article to another. The best relevant way is to use their API if possible.
