What's the max value of max_input_time?

Question

Seems that max_execution_time is 0 but memory_limit is -1.

For max_input_time is it 0 or -1 or both?

Answer 1

The absolute maximum value is the limit of the long type in C:

long max_input_time; member in struct:_php_core_globals 

See: http://lxr.php.net/search?q=max_input_time&defs=&refs=&path=&hist=&project=PHP_5_4

The effective maximum value is 2147483647, to maintain interoperability. It may be more on a specific platform or implementaion, but this is the most common, 32bit max.

As you can also see at a few spots in the source (ie if (PG(max_input_time) != -1)), the value -1 is treated as equivalent to maximum. 0 would be treated as zero.
