Table 173.  Misc. Configuration Options

Name Default Changeable Changelog
ignore_user_abort "0" PHP_INI_ALL  
highlight.string "#DD0000" PHP_INI_ALL

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

Here's a short explanation of the configuration directives.

ignore_user_abort boolean

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.php string , highlight.keyword string , highlight.string string

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

browscap string
