    When upload same files or same name the script replace old file . How to skip new file if already exist.
    // Check if form has been submitted
    if(@$_POST['submit']){
    ini_set("max_execution_time", 0);  // no time-outs!
    ignore_user_abort(true);   // Continue downloading even after user closes the browser.
    // URLS -- One on each line
    $URL = $_POST['url'];
    // Relative path to Save downloaded images
    // Default is "downloads"
    // Make sure that it is writable (chmoded correctly)
    $folder = $_POST['folder'];
    // Check if User has provided a local folder
    if (!$folder || !isset($folder)){
    // Generate error if left blank by user.
    die ("Please specify local folder name");
    }
    // Split all URLS into an array
    $urls = split("\n", $URL);
    // Remove Carriage Returns (useful for Windows-based browsers)
    $urls = str_replace("\r", "", $urls);
    $mh = curl_multi_init();
    foreach ($urls as $i => $url) {
    $path = pathinfo($url);
    $g=$folder . "/" . $path["basename"] ;
    // Check if file already exists on local folder.
    if(file_exists($g)){
    // If exists, delete the file so it always contains the latest update.
    unlink($g) or die("Unable to delete existing '$g'!");
    }
    // Update the user of what's going on
    echo "$i) Downloading: from <b>$url</b> to <a href=\"$g\"><b>$g</b></a><br />";
    if(!is_file($g)){
    $conn[$i]=curl_init($url);
    $fp[$i]=fopen ($g, "w");
    curl_setopt ($conn[$i], CURLOPT_FILE, $fp[$i]);
    curl_setopt ($conn[$i], CURLOPT_HEADER ,0);
    // curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,1000);
    curl_multi_add_handle ($mh,$conn[$i]);
    }
    }
    do {
        if (curl_multi_select($mh, 0.25) == -1) {
            usleep(170);
        }
    
        $n = curl_multi_exec($mh, $active);

    http://php.net/manual/en/function.file-exists.php

    You have this:
    
    if(file_exists($g)){
    // If exists, delete the file so it always contains the latest update.
    unlink($g) or die("Unable to delete existing '$g'!");
    }
    
    Code (php):
    So stop here instead of unlinking.
