Question: We are designing a system for conducting a survey in which it askes user a about 72 questions (Multiple Choice questions)
And when the user submits this will be posted to php page which will save the answer in a MySQL table. 
Its works fine and perfectly well when we doing the test with a small number of user
But I observed the when a large amount of users are submitting not all data reaches the server only a part of some users answer (around 65 answer) only reaches the server.But i get data from my all users but some answers aren't compete.
Am using MySql engine : MyISAM 
What would be the problem or how can i solve this. is it the problem with some php configuration or mysql (large number of insert statement)
What is the best way to handle larger amount data from a form submission php
Thanks in Advance

Answer: 
You need to Increase max\_input\_vars from php.ini OR you can set the following code in your .htaccess file.

```
php_value max_input_vars 3000

```
You should use the ajax function for post the data..
