<form enctype="multipart/form-data" action="upload.php" method="POST"> 
<!-- MAX_FILE_SIZE must precede the file input field --> 
<input type="hidden" name="MAX_FILE_SIZE" value="100000000" /> 
<!-- Name of input element determines name in $_FILES array --> 
Send this file: <input name="userfile" type="file" /> 
<input type="submit" value="Send File" />

nginx+linux環(huán)境注意事項

php環(huán)境上傳大文件需要注意的事項：

/usr/local/php/etc/php-fpm.conf.default
request_terminate_timeout = 0   //這個是fastcgi的執(zhí)行時間，默認不限制的
client_max_body_size 256m;

fastcgi_buffer_size 256k;
fastcgi_buffers 16 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
    
fastcgi_connect_timeout 3000;
fastcgi_send_timeout 3000;
fastcgi_read_timeout 3000;

另外PHP也需要配置：

memory_limit 512M
max_execution_time 0
post_max_size 256M
upload_max_filesize 256M

apache+windows環(huán)境下注意事項

配置php.ini文件 （以上傳500M以下大小的文件為例） 
查找以下選項并修改-> 
file_uploads = On ;打開文件上傳選項 
upload_max_filesize = 500M ;上傳文件上限

如果要上傳比較大的文件，僅僅以上兩條還不夠，必須把服務器緩存上限調大，把腳本最大執(zhí)行時間變長 
post_max_size = 500M ;post上限 
max_execution_time = 1800 ; Maximum execution time of each script, in seconds腳本最大執(zhí)行時間 
max_input_time = 1800 ; Maximum amount of time each script may spend parsing request data 
memory_limit = 128M ; Maximum amount of memory a script may consume (128MB)內存上限
