The upload. php script that receives Multiple File Uploads at a time is as follows:

 $ Error) {if ($ error = UPLOAD_ERR_ OK) {// PHP constant UPLOAD_ERR_ OK value is 0, $ temp_name = $ fileArray ['tmp _ name'] [$ key]; $ file_name = $ fileArray ['name'] [$ key]; move_uploaded_file ($ temp_name, $ upload_dir. $ file_name); echo 'upload [file '. $ key. ':'. $ file_name. '] successful! ';} Else {echo' An error occurred while uploading [File '. $ key.': '. $ file_name! ';}}?>

For the size limit of uploaded files, there are two restrictions on nginx and php for my current nginx + php-fpm.
The default Request body is 1 MB. you can adjust it in the configuration file/etc/nginx. conf:

Http {include/etc/nginx/mime. types; default_type application/octet-stream ;? Client_max_body_size 10 M; # set the maximum body size ...}

If the client_max_body_size limit is exceeded, nginx returns a 413 response code indicating "Request Entity Too Large ".

PHP limits the size of post request content:
The/etc/php. ini file contains the following content:

?; Maximum amount of time each script may spend parsing request data. It's a good; idea to limit this time on productions servers in order to eliminate unexpectedly; long running scripts.; http://www.php.net/manual/en/info.configuration.php#ini.max-input-timemax_input_time = 60?; Maximum size of POST data that PHP will accept.; http://www.php.net/manual/en/ini.core.php#ini.post-max-sizepost_max_size = 10M?; Whether to allow HTTP file uploads.; http://www.php.net/manual/en/ini.core.php#ini.file-uploadsfile_uploads = On?; Maximum allowed size for uploaded files.; http://www.php.net/manual/en/ini.core.php#ini.upload-max-filesizeupload_max_filesize = 10M
