with php, it is easy to upload files to the server. however, with ease comes danger, so always be careful when allowing file uploads! configure the "php.ini" file. first, ensure that php is configured to allow file uploads. in your "php.ini" file, search for the file_uploads directive, and set it to on: file_uploads = on. create the  $_files['file']['tmp_name']; will contain the temporary file name of the file on the server. this is just a placeholder on your server until you process the file. $_files['file']['name']; contains the original name of the uploaded file from the user's computer. if they all have the same length you can do it like this for($i = ; $i < count($_files['attachment']['name']); $i) { echo $_files['attachment']['name'][$i] . " "; echo $_files['attachment']['type'][$i] . " "; echo $_files['attachment']['size'][$i] . " "; echo $_files['attachment']['error'][$i] . " "; }.

here's a checklist for file uploading in php: check php.ini for: file_uploads = on post_max_size = m upload_max_filesize = m. you might need to use .htaccess or .user.ini if you are on shared hosting and don't have access to php.ini . make sure you're editing the correct ini file use the phpinfo()  your example form should work fine. it's just that you are expecting the structure of the $_files superglobal to be different than it actually is, when using an array structure for the field names. the structure of this multidimensional array is as followed then: $_files[fieldname] => array( [name] => array(  array_keys will give you all keys. $keys = array_keys($_files["upload"]);. first: try to strict programming error_reporting(e_all | e_strict);. also you must use isset for check is index for array available or not if (isset($_post['submitbtn']) && isset($_files['avatar'])) { } also check php configuraion file_uploads "" upload_max_filesize "m" post_max_size "m"
