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

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