Краткое разъяснение конфигурационных директив.

`sybase.allow_persistent` boolean

  Whether to allow persistent Sybase connections.

`sybase.max_persistent` integer

  The maximum number of persistent Sybase connections per process. -1 means no limit.

`sybase.max_links` integer

  The maximum number of Sybase connections per process, including persistent connections. -1 means no limit.

`sybase.min_error_severity` integer

  Minimum error severity to display.

`sybase.min_message_severity` integer

  Minimum message severity to display.

`magic_quotes_sybase` boolean

  If `magic_quotes_sybase` is on, a single-quote is escaped with a single-quote instead of a backslash if magic_quotes_gpc or magic_quotes_runtime are enabled.

  > Замечание: Note that when `magic_quotes_sybase` is ON it completely overrides `magic_quotes_gpc` . In this case even when `magic_quotes_gpc` is enabled neither double quotes, backslashes or NUL's will be escaped.
