## Runtime Configuration

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

APD Configuration Options
Name | Default | Changeable | Changelog
--- | --- | --- | ---
apd.dumpdir | NULL | PHP_INI_ALL |
apd.statement_tracing | "0" | PHP_INI_ALL | Available since apd 0.9.

For further details and definitions of the PHP_INI_* constants, see the php.ini directives.

Here's a short explanation of the configuration directives.

`apd.dumpdir` string

  Sets the directory in which APD writes profile dump files. You can specify an absolute path or a relative path.

  You can specify a different directory as an argument to apd_set_pprof_trace().

`apd.statement_tracing` boolean

  Specfies whether or not to do per-line tracings. Turning this on (1) will impact the performance of your application.
