PHP multi-image Upload value

PHP multi-image Upload has a multi-image upload problem. Three image upload functions are specified in the INPUT file. after you have done this, you will find that the upload is successful and you can change the name automatically, and 3 cannot be renamed automatically. how can I change the name?

$ Uploaddir = "uploadfiles/"; // Set the file storage directory to include/$ type = array ("jpg", "gif", "bmp", "jpeg ", "png"); // set the type of the file to be uploaded $ patch = "uploadfiles/"; // path of the program // Obtain the file extension function fileext ($ filename) {return substr (strrchr ($ filename ,'. '), 1);} // Obtain the file extension function fileext2 ($ filename2) {return substr (strrchr ($ filename2 ,'. '), 1);} // get the file extension function fileext3 ($ filename3) {return substr (strrchr ($ filename3 ,'. '), 1 );} // Function random ($ length) {$ hash = 'Java-'; $ chars = 'callback'; $ max = strlen ($ chars)-1; mt_srand (double) microtime () * 1000000); for ($ I = 0; $ I <$ length; $ I ++) {$ hash. = $ chars [mt_rand (0, $ max)];} return $ hash ;} $ a = strtolower (fileext ($ _ FILES ['img1'] ['name']); $ B = strtolower (fileext2 ($ _ FILES ['img2'] ['name']); $ c = strtolower (f Ileext3 ($ _ FILES ['img3'] ['name']); // you can determine the file type if (!

?? Yes ??, No ?? Yes $ filename [0], $ filename [1], $ filename [2]; and ?? Yes $ filename [0], $ filename2 [0], $ filename3 [0]

Do {$ filename [0] = random (10); // Set the random number length $ name = implode (". ", $ filename); // $ name1 = $ name. ". mcncc "; $ uploadfile = $ uploaddir. $ name; $ filename [1] = random (10); // Set the random number length $ name2 = implode (". ", $ filename2); // $ name1 = $ name. ". mcncc "; $ uploadfile2 = $ uploaddir. $ name2; $ filename [2] = random (10); // Set the random number length $ name3 = implode (". ", $ filename3); // $ name1 = $ name. ". mcncc "; $ uploadfile3 = $ uploaddir. $ name3 ;}
