How Can I Save Images from URLs to My Server Using cURL in PHP?

Saving Files from URLs with CURL in PHP

In a bid to store an image from a specified URL onto a directory on a server, understanding how to utilize CURL in PHP is vital. Below are possible steps to achieve this:

Original Code:

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);

Improved Solution:

To enhance the functionality of the provided code, an alternative method is recommended:

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);
}

Additional Recommendation:

In your php.ini file, ensure that allow_url_fopen is set to enabled. This setting is crucial for enabling external URL access.
