Most of you must have encountered this while while importing a large database in PHP MyAdmin, or any other MySQL interface. There is server time out or maybe the file upload size is limited to say 2 MB or so. All you need to do is, you have to edit you php.ini file to increase the PHP memory limit and the file upload size. If you are using WAMP, try these:
In C:\wamp\bin\apache\apache2.2.8\bin\php.ini (go to the respective directory if WAMP is installed in a different location)
Find:
post_max_size = 8M
upload_max_filesize = 2M
max_execution_time = 30
max_input_time = 60
memory_limit = 8M
Change to:
post_max_size = 750M
upload_max_filesize = 750M
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1000M
Then restart wamp for the changes to effect.
Hope this was useful to you.
