php修改上传文件大小
在PHP中，可以通过修改配置文件或使用ini_set()函数来修改上传文件大小限制。 通过修改php.ini文件 找到php.ini文件，通常位于服务器的php安装目录下。 打开php.ini文件，找到”upload_max_filesize”和”post_max_size”两个配置项。 修改它们的值，例如将它们都设为”10M”，表示最大上传文件大小为10MB。 保存php.ini文件并重启服务器，使配置生效。 vim /usr/local/php/lib/php.ini ; Maximum allowed size for uploaded files. upload_max_filesize = 500M ; Maximum size of POST data that PHP will accept. post_max_size = 500M systemctl restart rc-local.service
