A PHP multi-image upload Class code example

How to use: Save the above code with the file name: more_upload_file.class.php, and include the file when you use it.

Share a PHP implementation of multi-image upload class, the type of file comments detailed features practical and has a certain degree of extensibility, which support GIF, JPG, JPEG, pjpeg, PNG format, multi-image upload function, rare PHP multi-image upload class. A practical PHP multi-image File upload class, which supports GIF, JPG, JPEG, pjpeg, PNG format, multi-image upload function, the class can also limit the type of pictures, upload the size of the image, set the upload directory, some submit judgment and other functions. In addition, the class is not limited to the image upload, you can upload txt/rar and other file types, just need to modify the code. Example, PHP multi-image upload class full function code. Handledate = Date (' m-d-y '); if (!empty (file_name)) {This, file_name = file_name; This, file_error = File_error; This, file_size = file_size; This, file_tmp_name = File_tmp_name; This, file_type = File_type; This, File_type_array = Array ('/', ' image/gif ', ' image/jpg ', ' image/jpeg ', ' image/pjpeg ', ' image/png '); This-File_type_real_array = Array (0.1, ' jpg ' = = 74707370, ' gif ' = = 7173, ' bmp ' = = 6677, ' png ' = 807871) ; This--show_execute_message, File_error, this and file_name, this and File_type, this and file_size); }} function __destruct () {This, file_name = NULL; This, file_error = NULL; This, file_size = NULL; This, file_tmp_name = NULL; This, file_type = NULL; Self:: totalsize = 0; } function Show_execute_message (Smfileerror, Smfilename, Smfiletype, smfilesize) {if (Smfileerror > 0) {switch (Smfileerror) { Case 1:smfilemessage = ' file exceeds the contract size of the server!
