XCIX. Sybase functions

Introduction

Requirements

Installation

To enable Sybase-DB support configure PHP --with-sybase[=DIR]. DIR is the Sybase home directory, defaults to /home/sybase. To enable Sybase-CT support configure PHP --with-sybase-ct[=DIR]. DIR is the Sybase home directory, defaults to /home/sybase.

Runtime Configuration

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

Table 1. Sybase configuration options

NameDefaultChangeable
sybase.allow_persistent"On"PHP_INI_SYSTEM
sybase.max_persistent"-1"PHP_INI_SYSTEM
sybase.max_links"-1"PHP_INI_SYSTEM
sybase.interface_file "/usr/sybase/interfaces"PHP_INI_SYSTEM

sybase.min_message_severity"10"PHP_INI_ALL
sybase.compatability_mode"Off"PHP_INI_SYSTEM
magic_quotes_sybase"Off"PHP_INI_ALL

Here is a short explanation of the configuration directives.

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.

sybase.compatability_mode boolean

Compatability 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 compatability mode will probably not stay around forever, so try applying whatever necessary changes to your code, and turn it off.

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.

Note: 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.

Table 2. Sybase-CT configuration options

NameDefaultChangeable
sybct.allow_persistent"On"PHP_INI_SYSTEM
sybct.max_persistent"-1"PHP_INI_SYSTEM
sybct.max_links"-1"PHP_INI_SYSTEM
sybct.min_server_severity"10"PHP_INI_ALL
sybct.min_client_severity"10"PHP_INI_ALL
sybct.hostnameNULLPHP_INI_ALL

Here is a short explanation of the configuration directives.

sybct.allow_persistent boolean

Whether to allow persistent Sybase-CT connections. The default is on.

sybct.max_persistent integer

The maximum number of persistent Sybase-CT connections per process. The default is -1 meaning unlimited.

sybct.max_links integer

The maximum number of Sybase-CT connections per process, including persistent connections. The default is -1 meaning unlimited.

sybct.min_server_severity integer

Server 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_severity integer

Client 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.hostname string

The name of the host you claim to be connecting from, for display by sp_who. The default is none.
