## Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

Counter configuration options
Name | Default | Changeable | Changelog
--- | --- | --- | ---
counter.reset_time | COUNTER_RESET_PER_REQUEST | PHP_INI_ALL |
counter.save_path | "" | PHP_INI_ALL |
counter.initial_value | "0" | PHP_INI_ALL |

For further details and definitions of the PHP_INI_* modes, see the Where a configuration setting may be set.

`counter.reset_time` integer
  counter.reset_time tells "counter" to reset the counter used by the basic interface. It may be any of the `COUNTER_RESET_*` constants (see below).
`counter.save_path` string
  Tells "counter" where to save data that has to persist between invocations of PHP (i.e. any counter that has COUNTER_RESET_NEVER or COUNTER_FLAG_SAVE). A file will be created at this path, which must be readable and writable to whatever user PHP is running as.
`counter.initial_value` integer
  Sets the initial value of the counter used by the basic interface whenever it is reset.
