Download files in batches

//File download
$host = $config['DB_HOST'];
$port = $config['DB_PORT'];
$user = $config['DB_USER'];
$pwd = $ config['DB_PWD'];
$conn = @ mysql_connect($host.":".$port, $user, $pwd) or die("{'status':0,'msg':'Database connection error' }");
if($dbc $conn)){
}else{
echo("Could not connect to mysql");
}
$sql = "SELECT link FROM `frame` where cid=1";
$result = mysql_query($sql);
while($row = mysql_fetch_assoc($result)){
$imagesURL = $row['link'];
file_put_contents(basename($imagesURL), file_get_contents($imagesURL));

$i++;

}

The above has introduced the batch downloading of files, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
