php 获取压缩包名

参考链接: https://segmentfault.com/q/1010000000721799

通过curl方式获取压缩包名:

function getFile($url, $save_dir = '', &$filename = '', $type = 0) {  

    if (trim($url) == '') {
        return false;
    }
    if (trim($save_dir) == '') {
        $save_dir = './';
    }
    if (0 !== strrpos($save_dir, '/')) {
        $save_dir.= '/';
    }
    //创建保存目录
    if (!file_exists($save_dir) && !mkdir($save_dir, 0777, true)) {
        return false;
    }
    //获取远程文件所采用的方法
    if ($type) {
        $ch = curl_init();
        $timeout = 5;
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);  

        curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);

        $tmpInfo = curl_exec($ch);
        list($headers, $body) = explode("\r\n\r\n", $tmpInfo, 2);

        // echo $headers;

        $header_array = explode("\n", $headers);

        // print_r($header_array);

        foreach($header_array as $header_value) {

            $header_pieces = explode(':', $header_value);
            if(count($header_pieces) > 1) {

                  for ($i=0; $i <(count($header_pieces)/2) ; $i++) {
                      $headersArr[$header_pieces[$i*2]] = trim($header_pieces[2*$i+1]);
                  }

            }
        }

        // print_r($headersArr);

        $file_name = $headersArr['Content-Disposition'];

        // echo $file_name;

        $filename = exec("echo '$file_name' | awk -F \"=\" '/filename/{print $2}'",$output,$ret);

        // echo $filename;

        // print_r($output);
        // $file_type = $headersArr['Content-Type'];
        $content = $body;

        // echo $file_name."<br>";
        // print_r($headers);

        // $content = curl_exec($ch);
        curl_close($ch);
    } else {
        ob_start();
        readfile($url);
        $content = ob_get_contents();
        ob_end_clean();
    }  

    // print_r($_SERVER);

    //echo $content;
    $size = strlen($content);
    //文件大小
    $fp2 = @fopen($save_dir . $filename, 'a');
    fwrite($fp2, $content);
    fclose($fp2);
    unset($content, $url);
    return array(
        'file_name' => $filename,
        'save_path' => $save_dir . $filename,
        'file_size' => $size
    );  

}

2、curl -O -d "key=val" url 这样返回的内容就保存为同名文件了。
