Executes a previously parsed statement.
statementA valid OCI statement identifier.
modeAllows you to specify the execution mode (default is OCI_COMMIT_ON_SUCCESS).
If you don't want statements to be committed automatically, you should
specify OCI_DEFAULT as your
mode.
When using OCI_DEFAULT mode, you're creating a transaction. Transactions are automatically rolled back when you close the connection, or when the script ends, whichever is soonest. You need to explicitly call oci_commit() to commit the transaction, or oci_rollback() to abort it.
Note: In PHP versions before 5.0.0 you must use ociexecute() instead. This name still can be used, it was left as alias of oci_execute() for downwards compatability. This, however, is deprecated and not recommended.
