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。
