Oto krótkie wyjaśnienie dyrektyw konfiguracji.
sybase.allow_persistentbooleanWhether to allow persistent Sybase connections.
sybase.max_persistentintegerThe maximum number of persistent Sybase connections per process. -1 means no limit.
sybase.max_linksintegerThe maximum number of Sybase connections per process, including persistent connections. -1 means no limit.
sybase.min_error_severityintegerMinimum error severity to display.
sybase.min_message_severityintegerMinimum message severity to display.
sybase.compatability_modebooleanCompatibility mode with old versions of PHP 3.0. If on, this will cause PHP to automatically assign types to results according to their Sybase type, instead of treating them all as strings. This compatibility mode will probably not stay around forever, so try applying whatever necessary changes to your code, and turn it off.
magic_quotes_sybasebooleanIf
magic_quotes_sybaseis on, a single-quote is escaped with a single-quote instead of a backslash if magic_quotes_gpc or magic_quotes_runtime are enabled.Notatka: Note that when
magic_quotes_sybaseis ON it completely overridesmagic_quotes_gpc. In this case even whenmagic_quotes_gpcis enabled neither double quotes, backslashes or NUL's will be escaped.

| sybct.deadlock_retry_count | "0" | PHP_INI_ALL | Available since PHP 4.3.0. |
Oto krótkie wyjaśnienie dyrektyw konfiguracji.
sybct.allow_persistentbooleanWhether to allow persistent Sybase-CT connections. The default is on.
sybct.max_persistentintegerThe maximum number of persistent Sybase-CT connections per process. The default is -1 meaning unlimited.
sybct.max_linksintegerThe maximum number of Sybase-CT connections per process, including persistent connections. The default is -1 meaning unlimited.
sybct.min_server_severityintegerServer messages with severity greater than or equal to sybct.min_server_severity will be reported as warnings. This value can also be set from a script by calling sybase_min_server_severity(). The default is 10 which reports errors of information severity or greater.
sybct.min_client_severityintegerClient library messages with severity greater than or equal to sybct.min_client_severity will be reported as warnings. This value can also be set from a script by calling sybase_min_client_severity(). The default is 10 which effectively disables reporting.
sybct.login_timeoutintegerThe maximum time in seconds to wait for a connection attempt to succeed before returning failure. Note that if max_execution_time has been exceeded when a connection attempt times out, your script will be terminated before it can take action on failure. The default is one minute.
sybct.timeoutintegerThe maximum time in seconds to wait for a select_db or query operation to succeed before returning failure. Note that if max_execution_time has been exceeded when an operation times out, your script will be terminated before it can take action on failure. The default is no limit.
sybct.hostnamestringThe name of the host you claim to be connecting from, for display by sp_who. The default is none.
sybct.deadlock_retry_countintAllows you to define how often deadlocks are to be retried. The default is -1, or "forever".
