PHP Manual: Runtime Configuration

Runtime Configuration

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

**Sybase configuration options**
Name	Default	Changeable	Changelog
sybase.allow_persistent	"1"	PHP_INI_ALL	PHP_INI_ALL in PHP <= 4.0.2. PHP_INI_SYSTEM in PHP <= 4.0.3.
sybase.max_persistent	"-1"	PHP_INI_ALL	PHP_INI_ALL in PHP <= 4.0.2. PHP_INI_SYSTEM in PHP <= 4.0.3.
sybase.max_links	"-1"	PHP_INI_ALL	PHP_INI_ALL in PHP <= 4.0.2. PHP_INI_SYSTEM in PHP <= 4.0.3.
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	"0"	PHP_INI_ALL
magic_quotes_sybase	"0"	PHP_INI_ALL	Deprecated in PHP 5.3.0. Removed in PHP 5.4.0.

Here's 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.
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. This setting is also respected by addslashes and stripslashes.

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.

Warning
This feature has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

**Sybase-CT configuration options**
Name	Default	Changeable	Changelog
sybct.deadlock_retry_count	"0"	PHP_INI_ALL	Available since PHP 4.3.0.

Here's a short explanation of the configuration directives.

sybct.login_timeout integer: 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.
sybct.timeout integer: 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.
sybct.deadlock_retry_count int: Allows you to define how often deadlocks are to be retried. The default is 0, value -1 means "forever".
