Answer 1

l'idée de base

<?php 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_HEADER, 0); 
    curl_setopt($ch, CURLOPT_VERBOSE, 0); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)"); 
    curl_setopt($ch, CURLOPT_URL, _VIRUS_SCAN_URL); 
    curl_setopt($ch, CURLOPT_POST, true); 
    // same as <input type="file" name="file_box"> 
    $post = array(
     "file_box"=>"@/path/to/myfile.jpg", 
     "username"=>"foobar", 
     "password"=>"secret", 
     "submit"=>"submit" 
    ); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post); 
    $response = curl_exec($ch); 
?>

<?php

    if ($_FILES["file"]["error"] > 0) 
    { 
     $error = $_FILES["file"]["error"]; 
     echo "{error: '". $error ."', msg: ''}"; 
    } 
    else

     $fields = array(
