寫一個函數，擷取一篇文章内容中的全部圖檔，并下載下傳

function download_images($article_url = '', $image_path = 'tmp'){

    // 擷取文章類容
    $content = file_get_contents($article_url);

    // 利用正規表達式得到圖檔連結
    $reg_tag = '/<img.*?\"([^\"]*(jpg|bmp|jpeg|gif|png)).*?>/';
    $ret = preg_match_all($reg_tag, $content, $match_result); 
    $pic_url_array = array_unique($match_result1[1]);

    // 建立路徑
    $dir = getcwd() . DIRECTORY_SEPARATOR .$image_path;
    mkdir(iconv("UTF-8", "GBK", $dir), 0777, true);

    foreach($pic_url_array as $pic_url){
        // 擷取檔案資訊
        $ch = curl_init($pic_url);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_NOBODY, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE );
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE );
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $fileInfo = curl_exec($ch);
        $httpinfo = curl_getinfo($ch);
        curl_close($ch);

        // 擷取圖檔檔案字尾
        $ext = strrchr($pic_url, '.');
        $filename = $dir . '/' . uniqid() . $ext; 

        // 儲存圖檔資訊到檔案
        $local_file = fopen($filename, 'w');
        if(false !== $local_file){
            if( false !== fwrite($local_file, $filecontent) ){
            fclose($local_file);
            }
        }
    }

}
