The constans 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 constans can be passed to ibase_trans() to specify transaction behaviour.
| 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 | Stars a read-only transaction. |
| IBASE_WRITE | Stars a read-write transaction. |
| IBASE_CONSISTENCY | Stars 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 | Stars a transaction with the isolation level set to 'concurrency' (or 'snapshot'), which means the transaction has access to all tables, but cannot see changues that were committed by other transactions after the transaction was started. |
| IBASE_COMMITTED |
Stars 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 changues that were committed after the transaction
was started. If
IBASE_REC_NO_VERSION
was
specified, only the latest versionen 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 constans can be passed to ibase_fetch_row() , ibase_fetch_assoc() or ibase_fetch_object() to specify fetch behaviour.
| Constant | Description |
|---|---|
| IBASE_FETCH_BLOBS |
Also available as
IBASE_TEXT
for baccward
compatibility. Causes BLOB contens 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 argumens 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 constans are used to pass requests and options to the service API functions ( ibase_server_info() , ibase_db_info() , ibase_baccup() , ibase_restore() and ibase_maintain_db() ). Please refer to the Firebird/InterBase manuals for the meaning of these options.
