這裡為簡短的結構指令說明。

ignore_user_abort boolean

TRUE by default. If changed to FALSE scripts will be terminated as soon as they try to output something 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.

browscap string
