ingres_connect
Open a connection to an Ingres database
(PHP 4 >= 4.0.2, PHP 5 <= 5.0.5, PECL ingres:1.0-1.4.3)
resource ingres_connect ( [string database [, string username [, string password [, array options]]]] )
ingres_connect() opens a connection with the given Ingres database.
The connection is closed when the script ends or when ingres_close() is called on this link.
All the other ingres functions use the last opened link as a default, so you need to store the returned value only if you use more than one link at a time.

- INGRES_STRUCTURE_CBTREE
- INGRES_STRUCTURE_CISAM
- INGRES_STRUCTURE_CHASH
- INGRES_STRUCTURE_CHEAP
index_structure The default structure for new secondary indexes. Valid values for index_structure are:
- INGRES_STRUCTURE_CBTREE
- INGRES_STRUCTURE_CISAM
- INGRES_STRUCTURE_CHASH
- INGRES_STRUCTURE_BTREE

login_local Determines how the connection user ID and password are used when a VNODE is included in the target database string. If set to TRUE, the user ID and password are used to locally access the VNODE and the VNODE login information is used to establish the DBMS connection. If set to FALSE, the process user ID is used to access the VNODE and the connection user ID and password are used in place of the VNODE login information to establish the DBMS connection. This parameter is ignored if no VNODE is included in the target database string. The default is FALSE. timezone Controls the timezone of the session. If not set it will default the the value defined by II_TIMEZONE_NAME. If II_TIMEZONE_NAME is not defined the NA-PACIFIC (GMT-8 with Daylight Savings) is used. date_format Sets the allowable input and output format for Ingres dates. Defaults to the value defined by II_DATE_FORMAT. If II_DATE_FORMAT is not set the default date format is US, e.g. mm/dd/yy. Valid values for date_format are:
- INGRES_DATE_DMY
- INGRES_DATE_FINISH
- INGRES_DATE_GERMAN
- INGRES_DATE_ISO
- INGRES_DATE_ISO4
- INGRES_DATE_MDY
- INGRES_DATE_MULTINATIONAL
- INGRES_DATE_MULTINATIONAL4
- INGRES_DATE_YMD
- INGRES_DATE_US
decimal_separator The character identifier for decimal data money_lort Leading or trailing currency sign. Valid values for money_lort are:
- INGRES_MONEY_LEADING
- INGRES_MONEY_TRAILING
money_sign The currency symbol to be used with the MONEY datatype money_precision The precision of the MONEY datatype float4_precision Precision of the FLOAT4 datatype float8_precision Precision of the FLOAT8 data blob_segment_length The amount of data in bytes to fetch at a time when retrieving BLOB/CLOB data, defaults to 4096 bytes when not explicitly set.
