php批量下载图片,网上找的代码,不好使
function project_statistics(){ echo "11111"; $url = "http://www.xxx.com:81/upload/image"; $content=file_get_contents($url); $reg="/<img src="/static/imghw/default1.png" data-src="'.basename($url).'" class="lazy" .*?src=\"(.*?)\".*? alt="php批量下载图片,网上找的代码,不好使" >/"; preg_match_all($reg,$content,$matches); $path = '../download/img'; if(!file_exists($path)){ mkdir($path, 0777); } function downImage($url,$filename="") { if($url=="") return false; if($filename=="") { $ext=strrchr($url,"."); if($ext!=".gif" && $ext!=".jpg" && $ext!=".png" && $ext!="jpeg") return false; $filename=date("YmdHis").$ext; } ob_start(); //make file that output from url goes to buffer readfile($url); //file_get_contents($url); 这个方法不行的!!!只能用readfile $img = ob_get_contents(); ob_end_clean(); $fp=@fopen($filename, "a");//append fwrite($fp,$img); fclose($fp); return $filename; } for($i = 0;$i < count($matches[1]);$i ++){ /*explode $url_arr[$i] = explode('/', $matches[1][$i]); $last = count($url_arr[$i])-1; */ //strrchr $filename = strrchr($matches[1][$i], '/'); downImage($matches[1][$i],$path.$filename); //downImage($matches[1][$i],$path.'/'.$url_arr[$i][$last]); } }
求教 ,谢谢。 就是想把上传到服务器上的图片,都下载本地。这个还需要改
回复讨论(解决方案)
你给出的代码是采集目标网页上所有的图片标签,并下载之。。
你如果想下载上传到服务器上的图片,那你可以尝试通过上述代码中的downImage函数,把服务器上图片的url地址传入下载之。
能给例子否? 呵呵
有?片url??
循?所有url,然後使用file_get_contents下?就可以了。
例如:
$url = "http://www.abc.com/1.jpg';
$c = file_get_contents($url);
file_put_contents(basename($url), $c, true);
照你的写法做了,刷新浏览器, 是空白。 是不是还要配合什么函数才能下载下来? 谢谢
另外还有个疑问,如果多个图片的话 ,它是把所有的地址都放到一下类似迅雷的下载列表吗?
我写的是
$url = "http://www.hrb.com:81/upload/image/1.jpg";
$c = file_get_contents($url);
file_put_contents(basename($url), $c, true);
die();
附上真实图片地址:
?行後,在本地同?目??找到1.jpg的。
$url = "https://ss0.bdstatic.com/5a21bjqh_Q23odCf/static/superplus/img/logo_white_ee663702.png";$c = file_get_contents($url);file_put_contents(basename($url), $c, true); echo '<img src="/static/imghw/default1.png" data-src="'.basename($url).'" class="lazy" .basename($url).'" alt="php批量下载图片,网上找的代码,不好使" >';
有点糊涂了,本地同级目录,我本机没有upload/image目录啊
这个怎么找, 它的运行会自动在客户端的 C盘 或D盘下建个文件夹,然后把1.jpg放里面?

就是你那?php的目?。?php文件同一?的。
看到文件了, 感觉有点像移动文件。移动到另外一个目录下, 能下载到我电脑上吗? 如果这些图片在网络的服务器上
比如下载到桌面, 是不是 改个参数就行了?
比如下载到桌面, 是不是 改个参数就行了?
用哪台??行??php,就只能?取到哪台?。
如果你本?就是服?器,apache也?有?限放到你桌面的。除非你?置桌面文件??apache用?可?。
然後file_put_contents那?,把路??入
file_put_contents('/桌面/'.basename($url), $c, true);
也就是说 批量下载图片、批量下载文件这样的功能, 使用上边的这些方法不太好了,是吧?
应该把整个文件夹压缩,然后给个压缩包的地址,让用户下载。 是这样吗?
如果是??客?端用?,?然zip比?好啦。
多谢

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.
