PHP Question

What is the size limit of a post request?

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. I haven't run into any problems yet, but knowing this ahead of time might save me a bunch of frustration and work. Is there a size limit to posting data via http?

This article says no:

This discussion says yes:

And it all goes back and forth what I'm able to find online. So please limit answers to personally tested/verified numbers.

I am wanting to post back an XML string that can be quite large (say up to 5mb).

If it makes any difference: browser will always be IE (our product requires it), post is coming from and httpService in flex, web server is php, DB is mySql.


It's a server configuration. If you're working with PHP under Linux or similiar, you can control these using .htaccess, like so:

#set max post size
php_value post_max_size 20M

And, yes, I can personally attest to the fact that this works :)

If you're using IIS, I don't have any idea how you'd set this particular value.
