How to download images from url in xml value using php?

Question

I have to download images from url in an xml code and save it to a folder. Is there a way that I can do that? And, if I updated one of the picture, and I want to download it again, what should I do so that images that I download only the one that get updated (only the newest version is downloaded), if an image is not updated it won't be downloaded again. Thank you for your help! the xml example is this:

<item>
<g:main_image_url>https://www.dropbox.com/s/3tsncqxysqdyz1v/whitebag.jpg?dl=0</g:main_image_url>
</item>
<item>
<g:main_image_url>https://www.dropbox.com/s/vwks0iatjut2om4/whiteblackbag.jpg?dl=0</g:main_image_url>
</item>

this is the complete xml or some part of xml?

Try this, It will help you

$imageLink = "GET URL LINK FROM XML";
$random = mt_rand();
$filename = $random . ".jpg";
$path = "/images/";
file_put_contents(getcwd() . $path . $filename, file_get_contents($imageLink));

Get the $imageLink from XML using various string functions...
Happy Coding :-)

I've solved the code. I'll be running the php script with windows task scheduler, in order to update the image file that I have downloaded. In the 2nd download and so on, I only want to download images that are new. How can I do that? Am I going to use imagesize as the if condition or the image's name?

I've come up with the answer, and the code is like this

<?php
ini_set('max_execution_time', 300);
$doc = simplexml_load_file('xml_file.xml');
foreach ( $doc->xpath("//item") as $item )  {
    $name = $item->productname;
    $url = $item->thumbnail_url;
    $img = 'path/to/file/'.$name.'.png';
    file_put_contents($img, file_get_contents($url));    
}

?>
