Description:
------------
I am using PHP 5.3.3-7+squeeze7 on Debian+Apache2.

I cann´t change the parameter max_input_vars.

<?
ini_set("max_input_vars","5000");
phpinfo();
?>

A change of max_input_vars in php.ini does not work too. phpinfo() displays the correctly changed value, but the internal value of max_input_vars is not changed and is always 1000.

As http://au2.php.net/manual/en/info.configuration.php says, max_input_vars is PHP_INI_PERDIR, so can't be set with ini_set().

ok, max_input_vars cant´t be set using ini_set().  I did not know that - thanks.

But i cant´t set max_input_vars in php.ini too. phpinfo() displays the correctly changed value (for example max_input_vars=5000), but the array-input-variables with index > 1000 are truncated. (sorry for my english, i hope you can understand me)

SOLVED :-)

It was suhosin. The parameters:

suhosin.get.max_vars
suhosin.post.max_vars 
suhosin.request.max_vars

overwrite max_input_vars in php.ini.
That´s confused.

Hello, can you explain how you were able to change the max_input_vars directive?  
Exactly which file did you edit and what is the code needed to change it to 
something other than 1,000?
