Here's a short explanation of the configuration directives.
- ibase.allow_persistent boolean
Whether to allow persistent connections to Firebird/InterBase.
- ibase.max_persistent integer
The maximum number of persistent Firebird/InterBase connections per process. New connections created with ibase_pconnect() will be non-persistent if this number would be exceeded.
- ibase.max_links integer
The maximum number of Firebird/InterBase connections per process, including persistent connections.
- ibase.default_db string
The default database to connect to when ibase_[p]connect() is called without specifying a database name. If this value is set and SQL safe mode is enabled, no other connections than to this database will be allowed.
- ibase.default_user string
The user name to use when connecting to a database if no user name is specified.
- ibase.default_password string
The password to use when connecting to a database if no password is specified.
- ibase.default_charset string
The character set to use when connecting to a database if no character set is specified.
- ibase.timestampformat string
- ibase.dateformat string
- ibase.timeformat string
These directives are used to set the date and time formats that are used when returning dates and times from a result set, or when binding arguments to date and time parameters.
Predefined Constants
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
The following constants can be passed to ibase_trans() to specify transaction behaviour.
Table 2. Firebird/InterBase transaction flags
| Constant | Description |
|---|---|
| IBASE_DEFAULT | The default transaction settings are to be used. This default is determined by the client library, which defines it as IBASE_WRITE|IBASE_CONCURRENCY|IBASE_WAIT in most cases. |
| IBASE_READ | Starts a read-only transaction. |
| IBASE_WRITE | Starts a read-write transaction. |
| IBASE_CONSISTENCY | Starts a transaction with the isolation level set to 'consistency', which means the transaction cannot read from tables that are being modified by other concurrent transactions. |
| IBASE_CONCURRENCY | Starts a transaction with the isolation level set to 'concurrency' (or 'snapshot'), which means the transaction has access to all tables, but cannot see changes that were committed by other transactions after the transaction was started. |
| IBASE_COMMITTED | Starts a transaction with the isolation level set to 'read committed'. This flag should be combined with either IBASE_REC_VERSION or IBASE_REC_NO_VERSION. This isolation level allows access to changes that were committed after the transaction was started. If IBASE_REC_NO_VERSION was specified, only the latest version of a row can be read. If IBASE_REC_VERSION was specified, a row can even be read when a modification to it is pending in a concurrent transaction. |
| IBASE_WAIT | Indicated that a transaction should wait and retry when a conflict occurs. |
| IBASE_NOWAIT | Indicated that a transaction should fail immediately when a conflict occurs. |
The following constants can be passed to ibase_fetch_row(), ibase_fetch_assoc() or ibase_fetch_object() to specify fetch behaviour.
Table 3. Firebird/InterBase fetch flags
| Constant | Description |
|---|---|
| IBASE_FETCH_BLOBS | Also available as IBASE_TEXTfor backward compatibility. Causes BLOB contents to be fetched inline, instead of being fetched as BLOB identifiers. |
| IBASE_FETCH_ARRAYS | Causes arrays to be fetched inline. Otherwise, array identifiers are returned. Array identifiers can only be used as arguments to INSERT operations, as no functions to handle array identifiers are currently available. |
| IBASE_UNIXTIME | Causes date and time fields not to be returned as strings, but as UNIX timestamps (the number of seconds since the epoch, which is 1-Jan-1970 0:00 UTC). Might be problematic if used with dates before 1970 on some systems. |
The following constants are used to pass requests and options to the service API functions (ibase_server_info(), ibase_db_info (), ibase_backup(), ibase_restore () and ibase_maintain_db()). Please refer to the Firebird/InterBase manuals for the meaning of these options.
