Answer 1

查看您的PHP.INI文件配置。寻找入口upload_max_filesize并放置你想要的大小限制。然后重新启动服务器。

看起来应该是这样的：

 ;;;;;;;;;;;;;;;;
 ; File Uploads ;
 ;;;;;;;;;;;;;;;;

 ; Whether to allow HTTP file uploads.
 ; http://php.net/file-uploads
 file_uploads = On

 ; Temporary directory for HTTP uploaded files (will use system default if not
 ; specified).
 ; http://php.net/upload-tmp-dir
 upload_tmp_dir = "C:\Dev\xampp\tmp"

 ; Maximum allowed size for uploaded files.
 ; http://php.net/upload-max-filesize
 upload_max_filesize = 2M   <<<<<<----------------- THIS IS THE VALUE YOU MUST CHANGE

 ; Maximum number of files that can be uploaded via a single request
 max_file_uploads = 20

Answer 2

在PHP.ini中，将这些变量设置为上述值：

memory_limit = 96M
post_max_size = 64M
upload_max_filesize = 64M

如果文件大小超过100mb，PHP无法上传Document
