下面是從url下載文件的腳本。我想要的是多鏈接,如應該有三個或更多的輸入url框,其中用戶放置鏈接,腳本下載所有文件。我不想按一個按鈕,並出現另一個url框;那不是我想要的,我已經嘗試過了。或多重鏈接;這樣的事情,我們可以把鏈接在每一行:需要幫助才能使此捲曲腳本多鏈接
<?php
class Download {
const URL_MAX_LENGTH=2000;
// clean url
protected function cleanUrl($url){
if (isset($url)){
if (!empty($url)){
if(strlen($url)< self::URL_MAX_LENGTH){
return strip_tags($url);
}
}
}
}
//is url
protected function isUrl($url){
$url=$this->cleanUrl($url);
if (isset($url)){
if (filter_var($url, FILTER_VALIDATE_URL, FILTER_FLAG_PATH_REQUIRED)){
return $url;
}
}
}
//return extension
protected function returnExtension($url){
if ($this->isUrl($url)){
$end = end(preg_split("/[.]+/", $url));
