Save file from url with curl PHP

I need to save an image file from a url using CURL and save it to a folder on my server. I've been battling with this code to no avail. Ideally I'd like to grab the image and save it as "photo1" or something. Help!

function GetImageFromUrl($link)
{
     
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_POST, 0);
    curl_setopt($ch,CURLOPT_URL,$link);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}
    
$sourcecode = GetImageFromUrl($iticon);
$savefile = fopen(' /img/uploads/' . $iconfilename, 'w');
fwrite($savefile, $sourcecode);
fclose($savefile);

try this:

function grab_image($url,$saveto){
    $ch = curl_init ($url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    $raw=curl_exec($ch);
    curl_close ($ch);
    if(file_exists($saveto)){
        unlink($saveto);
    }
    $fp = fopen($saveto,'x');
    fwrite($fp, $raw);
    fclose($fp);
}

and ensure that in php.ini allow_url_fopen is enable
