Php implements batch download of images to local instances (anti-leech can be used)

For images without anti-Leech protection

The code is as follows:

Copy code

/* * For images without anti-Leech protection * $ Url Image address * $ Filename image storage address * Return the path and name of the downloaded image, and the image size. */ Function GrabImage ($ url, $ filepath, $ filename = ""){ If ($ url = "") return false;   $ Ext = strrchr ($ url ,"."); If ($ filename = ""){ If ($ ext! = ". Gif" & $ ext! = ". Jpg" & $ ext! = ". Png") return false; $ Filename = date ("YmdHis "); }   Ob_start (); Readfile ($ url ); $ Img = ob_get_contents (); Ob_end_clean (); $ Size = strlen ($ img); // Image size   ! Is_dir (getcwd (). $ filepath )? Mkdir (getcwd (). $ filepath): null; // Generate a folder   $ Fp2 = fopen (getcwd (). $ filepath. $ filename. $ ext, ""); Fwrite ($ fp2, $ img ); Fclose ($ fp2 );   Return array ($ filepath. $ filename. $ ext, $ size ); }

Images with anti-Leech protection
 

The code is as follows:

Copy code

/* * Images with anti-Leech protection * $ Url Image address * $ Filename image storage address * Return the path and name of the downloaded image, and the image size. * $ Fromurl: source URL. You can enter the source image URL to crack anti-Leech protection. */ Function GrabImage2 ($ url, $ filepath, $ filename = "", $ fromurl ){ If ($ url = "") return false;   $ Ext = strrchr ($ url ,"."); If ($ filename = ""){ If ($ ext! = ". Gif" & $ ext! = ". Jpg" & $ ext! = ". Png") return false; $ Filename = date ("YmdHis ");  }   ! Is_dir (getcwd (). $ filepath )? Mkdir (getcwd (). $ filepath): null; // Generate a folder   $ Re = $ this-> curlg ($ url, $ fromurl ); $ Size = file_put_contents (getcwd (). $ filepath. $ filename. $ ext, $ re); // return size   Return array ($ filepath. $ filename. $ ext, $ size ); }

Batch collection code:

The code is as follows:

Copy code

/** * Batch download of images */ Public function downimg (){ $ Keep = $ this-> _ get ("keep"); // 1 get from cache 2 delete cache/recache $ Id = $ this-> _ get ("id "); $ Id = $ id? $ Id: 0; $ Nextid = $ id + 1; If ($ keep! = 1 ){ $ Data = M ('cjlist')-> where ("status = 1")-> select (); S ("keepcjdata", $ data, 3600 ); } Else { $ Data = S ("keepcjdata "); } $ Endid = count ($ data ); // Echo $ id; // Echo $ endid; If ($ endid = $ id ){ Exit ('All images have been downloaded! '); } // Echo $ endid; $ Data2 ['cover _ imgurl'] = $ this-> imgdown2 ($ data [$ id] ['cover _ imgurl']); // Echo $ data [$ id] ['thum _ url']; $ Data2 ['thum _ url'] = $ this-> imgdown2 ($ data [$ id] ['thum _ url'], 'thum _'); // medium-sized image type $ Data2 ['id'] = $ data [$ id] ['id']; If (! $ Data2 ['thum _ url'] |! $ Data2 ['cover _ imgurl']) { $ Data2 ['status'] =-1; } Else { $ Data2 ['status'] = 2; } $ Res = M ('cjlist')-> save ($ data2 ); // $ This-> echosql (); If ($ res ){ Echo 'download completion ID :'. $ data2 ['id']. "go to the next ID to download <script> window. location. href = '". U ('index/downimg '). "/keep/1/id /". $ nextid. "'</script> "; } Else { Echo 'failed to save. Refresh again. <Script> window. location. reload () </script> '; } // Dump ($ data2 ); // Dump ($ data );   }

You can also generate thumbnails.

The code is as follows:

Copy code

/* * Image Collection saves local generation of thumbnails  * **/   Public function imgdown ($ picurl = 'http: // response '){ $ Mulu = "/". date ("YmdH", time ())."/"; $ Reimg = $ this-> GrabImage2 ($ picurl, $ mulu, time (), $ fromurl ); // $ Img = file_get_contents ($ picurl ); // Echo file_put_contents('222.jpg ', $ img ); // Exit; // $ Reimg = "/20140529/1401333398 .jpg "; // Dump ($ reimg ); // Exit; If ($ reimg [1] <= 0 ){ Exit ("failed to download image ");  } $ Reimg = $ reimg [0]; Import ('org. Util. Image '); $ Image = new Image (); $ Imgurl = getcwd (). $ reimg; $ Ext = strrchr ($ imgurl ,"."); $ Thum_name = $ Image-> thumb ($ imgurl, "thum _". time (). $ ext, '', '000000', '000000 '); Rename (getcwd (). "/". $ thum_name, getcwd (). $ mulu. $ thum_name); // move to the folder $ Imginfo = $ Image-> getImageInfo (getcwd (). $ mulu. $ thum_name ); // Dump ($ imginfo ); $ Imgarr ['cover _ url'] = $ reimg; $ Imgarr ['thum _ url'] = $ mulu. $ thum_name; $ Imgarr ['thum _ W'] = $ imginfo ['width']; $ Imgarr ['thum _ H'] = $ imginfo ['height']; Return $ imgarr;  }
