 Error_handler (); // Set the name of the saved Image. if not set, a unique file name $ this-> save_name = $ save_name? $ Save_name: md5 (mt_rand (), uniqid (); // you can specify the path for saving the image. if not, use the year, month, or day format for Directory Storage $ this-> save_dir = $ save_dir? Self: ROOT_PATH. $ save_dir: self: ROOT_PATH. date ('Y/m/D'); // create a folder @ $ this-> create_dir ($ this-> save_dir ); // Set the Directory + complete Image path $ this-> save_fullpath = $ this-> save_dir. '/'. $ this-> save_name;} // Compatible with PHP4 public function image ($ save_name) {$ this->__ construct ($ save_name);} public function stream2Image () {// binary data stream $ data = file_get_contents ('php: // input ')? File_get_contents ('php: // input'): gzuncompress ($ GLOBALS ['http _ RAW_POST_DATA ']); // if (! Empty ($ data) {// create and write data streams, and then save the file if (@ $ fp = fopen ($ this-> save_fullpath, 'W + ')) {fwrite ($ fp, $ data); fclose ($ fp); $ baseurl = "http ://". $ _ SERVER ["SERVER_NAME"]. ":". $ _ SERVER ["SERVER_PORT"]. dirname ($ _ SERVER ["SCRIPT_NAME"]). '/'. $ this-> save_name; if ($ this-> getimageInfo ($ baseurl) {echo $ baseurl;} else {echo (self: NOT_CORRECT_TYPE );}} else {} else {// not received Data stream echo (self: NO_STREAM_DATA) ;}/ *** create a folder * @ param String $ dirName folder pathname */public function create_dir ($ dirName, $ recursive = 1, $ mode = 0777 ){! Is_dir ($ dirName) & mkdir ($ dirName, $ mode, $ recursive);}/*** get image information, returns the image width, height, type, size, and image mine type * @ param String $ imageName image name */public function getimageInfo ($ imageName = '') {$ imageInfo = getimagesize ($ imageName); if ($ imageInfo! = False) {$ imageType = strtolower (substr (image_type_to_extension ($ imageInfo [2]), 1); $ imageSize = filesize ($ imageInfo ); return $ info = array ('width' => $ imageInfo [0], 'height' => $ imageInfo [1], 'type' => $ imageType, 'size' => $ imageSize, 'Mine '=> $ imageInfo ['Mine']);} else {// invalid image return false ;}} /* private function error_handler ($ a, $ B) {echo $ a, $ B;} */}?>
