How to use php to remotely collect images locally

Today, I wrote this function to share it with my friends. you can obtain remote images and save them to your local computer. In fact, you can refer to this function in many php management systems.

Step 1. extract all the regular expressions from the article.

The code is as follows:

$ Message // Article content // regular (this is not yet) $ reg = "/] * src = \" (http :\/\/(. + )\/(. + )\. (jpg | gif | bmp | bnp Paribas) \ "/isU"; // store the extracted img address in the $ img_array variable preg_match_all ($ reg, $ message, $ img_array, PREG_PATTERN_ORDER); // filter duplicate images $ img_array = array_unique ($ img_array [1]);

Step 2. loop through the $ img_array. save the image and replace the position of the article.

The code is as follows:

Foreach ($ img_array as $ img) {// Determine whether the image is on your website if ('XXX. com '! = Get_domain ($ img) {// if this image is not on your server, // read the image file $ Gimg = new GetImage (); $ Gimg-> source = $ img; $ Gimg-> save_to = '. /data/temp/'; $ FILE = $ Gimg-> download (); // move the image to a local location // save it to the album to get the image saved $ img_path = pic_save ($ FILE, 0 ,''); // replace the text path $ message = str_replace ($ img, $ img_path, $ message );}}

... At this time, the image in $ message has been replaced with the local address of your server, and the image is saved to your server.

The code is as follows:

// The following functions and classes are found on the network. // Obtain the domain name function get_domain ($ url) {$ pattern = "/[\ w-] + \ from the url \. (com | net | org | gov | cc | biz | info | cn )(\. (cn | hk) */"; preg_match ($ pattern, $ url, $ matches); if (count ($ matches)> 0) {return $ matches [0];} else {$ rs = parse_url ($ url); $ main_url = $ rs ["host"]; if (! Strcmp (long2ip (sprintf ("% u", ip2long ($ main_url), $ main_url) {return $ main_url;} else {$ arr = explode (". ", $ main_url); $ count = count ($ arr); $ endArr = array (" com "," net "," org "," 3322 "); // condition such as com.cn net.cn if (in_array ($ arr [$ count-2], $ endArr) {$ domain = $ arr [$ count-3]. ". ". $ arr [$ count-2]. ". ". $ arr [$ count-1];} else {$ domain = $ arr [$ count-2]. ". ". $ arr [$ count-1];} return $ domain;} // end if (! Strcmp ...)} // end if (count ...)} // end function // class GetImage {var $ source; var $ save_to; var $ quality; function download ($ method = 'curl') {$ info = @ GetImageSize ($ this-> source); $ mime = $ info ['Mime ']; // What sort of image? $ Type = substr (strrchr ($ mime, '/'), 1); switch ($ type) {case 'jpeg ': $ image_create_func = 'imagecreatefromjpeg '; $ image_save_func = 'imagejpeg '; $ new_image_ext = 'jpg'; // Best Quality: 100 $ quality = isSet ($ this-> quality )? $ This-> quality: 100; break; case 'PNG ': $ image_create_func = 'imagecreatefrompng'; $ image_save_func = 'imagepng '; $ new_image_ext = 'PNG '; // Compression Level: from 0 (no compression) to 9 $ quality = isSet ($ this-> quality )? $ This-> quality: 0; break; case 'bmp ': $ image_create_func = 'imagecreatefrombmp'; $ image_save_func = 'imagebmp '; $ new_image_ext = 'bmp'; break; case 'GIF': $ image_create_func = 'imagecreatefromgif '; $ image_save_func = 'imagegif'; $ new_image_ext = 'GIF'; break; case 'vnd. wap. wbmp ': $ image_create_func = 'imagecreatefromwbmp'; $ image_save_func = 'imagewbmp '; $ new_image_ext = 'bmp'; break; case 'xbm ': $ image_create_func = 'category '; $ image_save_func = 'imagexbm '; $ new_image_ext = 'xbm'; break; default: $ image_create_func = 'hangzhou'; $ image_save_func = 'imagejpeg '; $ new_image_ext = 'jpg ';} if (isSet ($ this-> set_extension) {$ ext = strrchr ($ this-> source ,". "); $ strlen = strlen ($ ext); $ new_name = basename (substr ($ this-> source, 0,-$ strlen )). '. '. $ new_image_ext;} else {$ new_name = basename ($ this-> source);} $ save_to = $ this-> save_to. "/blog_insert_temp _". time (). mt_rand (1, 99 ). ". ". $ new_image_ext; // the output object is the same as the $ _ FILE variable, and the result is the same as the normal image upload process. $ img_info ['name'] = basename ($ this-> source ); $ img_info ['type'] = $ mime; $ img_info ['size'] = 1000; $ img_info ['tmp _ name'] = $ save_to; $ img_info ['error'] = 0; if ($ method = 'curl') {$ save_image = $ this-> LoadImageCURL ($ save_to );} elseif ($ method = 'gd ') {$ img = $ image_create_func ($ this-> source); if (isSet ($ quality )) {$ save_image = $ image_save_func ($ img, $ save_to, $ quality);} else {$ save_image = $ image_save_func ($ img, $ save_to);} return $ img_info ;} function LoadImageCURL ($ save_to) {$ ch = curl_init ($ this-> source); $ fp = fopen ($ save_to, "wb "); // set URL and other appropriate options $ options = array (CURLOPT_FILE => $ fp, CURLOPT_HEADER => 0, CURLOPT_FOLLOWLOCATION => 1, CURLOPT_TIMEOUT => 60 ); // 1 minute timeout (shocould be enough) curl_setopt_array ($ ch, $ options); curl_exec ($ ch); curl_close ($ ch); fclose ($ fp );}}
