Fopen function

The code is as follows:

Function get_file ($ url, $ folder, $ pic_name ){ Set_time_limit (24*60*60); // you can specify the maximum execution time. $ Destination_folder = $ folder? $ Folder. '/': ''; // file download and save Directory $ Newfname = $ destination_folder. $ pic_name; // file PATH $ File = fopen ($ url, 'RB '); If ($ file ){ $ Newf = fopen ($ newfname, 'WB '); If ($ newf ){ While (! Feof ($ file )){ Fwrite ($ newf, fread ($ file, 1024*8), 1024*8 ); } } If ($ file ){ Fclose ($ file ); } If ($ newf ){ Fclose ($ newf ); } } } Get_file ("/img/baidu_logo.gif", "file", "baidu.jpg "); ?>

Php curl function

The code is as follows:

/* * Function: php supports multiple methods to download remote images and save them to a local device. * Parameter: file url, saving file name, used for download * When the name of the saved file is null, the original name of the remote file is used. */ Function getImage ($ url, $ filename = '', $ type = 0 ){ If ($ url = '') {return false ;} If ($ filename = ''){ $ Ext = strrchr ($ url ,'.'); If ($ ext! Using '.gif '& $ ext! Else '.jpg ') {return false ;} $ Filename = time (). $ ext; } // File storage path 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 ); $ Img = curl_exec ($ ch ); Curl_close ($ ch ); } Else { Ob_start (); Readfile ($ url ); $ Img = ob_get_contents (); Ob_end_clean (); } $ Size = strlen ($ img ); // File size $ Fp2 = @ fopen ($ filename, 'A '); Fwrite ($ fp2, $ img ); Fclose ($ fp2 ); Return $ filename; }

To enable the php curl function library

1) remove the file in windows/php. ini; prefix extension = php_curl.dll;/* use echo phpinfo () to view the php. ini path */

2) copy php5/libeay32.dll and ssleay32.dll to the system directory windows/
