## Runtime Configuration

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

Misc. Configuration Options
Name | Default | Changeable | Changelog
--- | --- | --- | ---
ignore_user_abort | "0" | PHP_INI_ALL |
highlight.string | "#DD0000" | PHP_INI_ALL |
highlight.comment | "#FF8000" | PHP_INI_ALL |
highlight.keyword | "#007700" | PHP_INI_ALL |

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

Here's a short explanation of the configuration directives.

  `FALSE` by default. If changed to `TRUE` scripts will not be terminated after a client has aborted their connection.

  See also ignore_user_abort().

`highlight.bg` string
`highlight.comment` string
`highlight.default` string
`highlight.html` string
`highlight.keyword` string
`highlight.string` string

  Colors for Syntax Highlighting mode. Anything that's acceptable in <font color="??????"> would work.
