Sorry if this is duplicate,I would think it would be but couldn\'t find anything.
I have a flex application that I am posting data back to a php/mysql server via IE.
You can post large amount of data by setting php.ini variable: max_input_vars
Default size of this variable is 1000 but if you want to sent large amount of data you have to increase the size accordingly.
If you can't set the size from ini_set you have to do it through htaccess
or by doing changes into php.ini file directly.
max_input_vars 2500
memory_limit 256M
