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.
这些函数的行为受到全局配置文件 php.ini 的影响。
表格 1. Sybase configuration options
| Name | Default | Changeable |
|---|---|---|
| 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_error_severity | "10" | PHP_INI_ALL |
| sybase.min_message_severity | "10" | PHP_INI_ALL |
| sybase.compatability_mode | "Off" | PHP_INI_SYSTEM |
| magic_quotes_sybase | "Off" | PHP_INI_ALL |
以下是该配置选项的简要解释。
Whether to allow persistent Sybase connections.
The maximum number of persistent Sybase connections per process. -1 means no limit.
The maximum number of Sybase connections per process, including persistent connections. -1 means no limit.
Minimum error severity to display.
Minimum message severity to display.
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.
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.
注: 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.
表格 2. Sybase-CT configuration options
| Name | Default | Changeable |
|---|---|---|
| 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.hostname | NULL | PHP_INI_ALL |
| sybct.deadlock_retry_count | "-1" | PHP_INI_ALL |
以下是该配置选项的简要解释。
Whether to allow persistent Sybase-CT connections. The default is on.
The maximum number of persistent Sybase-CT connections per process. The default is -1 meaning unlimited.
The maximum number of Sybase-CT connections per process, including persistent connections. The default is -1 meaning unlimited.
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.
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.
The 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.
The 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.
The name of the host you claim to be connecting from, for display by sp_who. The default is none.
Allows you to to define how often deadlocks are to be retried. The default is -1, or "forever".
