Later found a php bulk download picture file

If I now find that the image on a Web site is stored in the 1001–1999 directory is stored in the 1 (the number of different). jpg images, and now I decided to use the PHP method to download the image directly to the local style

Fake piece start address: http://image.xxx.com/img/1001/1.jpg
At this point I put 1001 places in the variable $id,1.jpg to the variable $num.jpg, save the file name is $id_$num.jpg
First make sure to create a folder named IMG and writable under this file execution directory

The code is as follows

Copy Code

$id = Isset ($_get[' id ") && intval ($_get[' id ') && $_get[' id ']>1000? $_get[' ID ']: 1001; $num = isset ($_get[' num ')) && intval ($_get[' num ')? $_get[' num ']: 1; $url = "http://image.xxx.com/img/{$id}/{$num}.jpg"; $array =get_headers ($url, 1); By returning 200 and 400来 the judgment is to increase the $id or $num if (Preg_match ('/200/', $array [0])) { $new _url= "? id={$id}&num=". ($num + 1); Ob_start (); ReadFile ($url); $img = Ob_get_contents (); Ob_end_clean (); $filename = "./img/{$id}_{$num}.jpg"; $f =fopen ($filename, ' a '); Fwrite ($f, $img); Fclose ($f); }else{ $new _url= "? id=". ($id + 1). " &num=1 "; } if ($id > 1999) exit (' complete '); Displays the current status echo $url, '-', $array [0], ';
