使用PHP将网页上的文件上传到服务器

Question

I have a php code which uploads my photos to a server. The code works fine for local files, but it is not working for files from Web. Below is my code for uploading local files

<?php

    $filepath="@/home/path/to/my/file.png";
    $serverurl ="https://cxdetails.com/upload.php";
    $ch=curl_init();
    curl_setopt($ch,CURLOPT_HEADER,0);
    curl_setopt($ch,CURLOPT_VERBOSE,0);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch,CURLOPT_URL, $serverurl);
    curl_setopt($ch,CURLOPT_POST,true);
    $post=array("file"=>$filepath);
    curl_setopt($ch,CURLOPT_POSTFIELDS,$post);
    $response=curl_exec($ch);
    echo $response;

?>

but it is not working if I change the $filepath to " http://www.howtocheck.zu/path/sarah.png ". Am not sure why this is not working. Please help me out on this.

Thanks in advance.
