I was wondering if there is a max length on a $_GET variable. I plan on using ajax with a get command and part of it is an encoding of an access key using one of my encoding methods. This method has returned back roughly 1530 characters and I was wondering if this it too long for a get variable as long as it's all URL encoded? Thanks in advance, Spencer

Browser would greatly affect the max length of your $_GET param
MAXIMUM LENGTH FOR BROWSERS REFERENCE
Some versions of PHP have a limitation of length of GET params:

Would I be better to send the AJAX request using post variables? I would assume those can be over 2000 characters – Spencer D Oct 02 '13 at 03:08

yes if you have largeSet of values needed to pass on abd it would be much more reliable also – Jhonathan H. Oct 02 '13 at 03:10

I take that back, according to http://support.microsoft.com/kb/208427, in ie at least, the max length for a post variable is also 2,048 characters. Anyways, I'll check into that link. Thanks for the help. – Spencer D Oct 02 '13 at 03:15

Please note that PHP setups with the suhosin patch installed will have a default limit of 512 characters for get parameters. Although bad practice, most browsers (including IE) supports URLs up to around 2000 characters, while Apache has a default of 8000.
To add support for long parameters with suhosin, add suhosin.get.max_value_length = in php.ini
