How to upload large file in php?

phpinfo();

?>

and search "Configuration File (php.ini) Path " row , there will
be an in output window and this  which will contain path  of php.ini file
in your PC

and in this php.ini file, change the variable size as per requirement

            upload_max_filesize = (size)M

            post_max_size = (size)M

new in php 5

            max_input_time = (value)   //in second

 max_input_time variable  which sets a time limit in seconds
for receiving input data through POST, GET, and PUT. If your application is
running over a slow link,

it is sometimes worthwhile to explore increasing this value to allow the
script more time to receive input data. or you can change this variable at
run time through programme

example

ini_set('post_max_size','9M')

now post_max_size variable is 9 MB set.

using

string ini_set ( string varname, string newvalue )

now i added client side validation for restricting user to upload more than
particular file size.

            value="30000" />

use this hidden variable and its value contain how many bytes allow to be
upload.

if you want store file in mysql Long blog data type.

set the variable

max_allowed_packet = (byte)

The above steps solved my problem and i can upload big file without any hurdle..
