When uploaded with PHP, you need to check the content, such as whether you allow reading and writing files, file format, and file size whether you specify in the size of you. $ file_size_max) {echo "Sorry, your file capacity is greater than the specified"; exit;} // check the read and write file IF (file_exists ($ store_dir. $ Upload_file_name) &&&&! $ Accept_overwrite {echo "File already exists, no replication"; exit;} // copy file to the specified directory IF (! @ Copy ($ upload_file, $ store_dir. $ Upload_file_name)) {Echo "copy file failed"; EXIT;} Echo "upload Documentation ";?> Need to note is that PHP is copied to the server temporary directory (TEMP) when the file is uploaded, and then use the PHP" Copy () "function to copy the file by the temporary directory to your specified storage. table of Contents. Since the program uses a temporary directory to work, if the server blocks the above features due to security issues, you cannot use the PHP upload function.
