true
, the SQLite3 instance, and SQLite3Stmt and SQLite3Result instances derived from it, will throw exceptions on error.When
false
, the SQLite3 instance, and SQLite3Stmt and SQLite3Result instances derived from it, will raise warnings on error.For either mode, the error code and message, if any, will be available via SQLite3::lastErrorCode() and SQLite3::lastErrorMsg() respectively.

范例
Example #1 SQLite3::enableExceptions() example
<?php$sqlite = new SQLite3(':memory:');try { $sqlite->exec('create table foo'); $sqlite->enableExceptions(true); $sqlite->exec('create table bar');} catch (Exception $e) { echo 'Caught exception: ' . $e->getMessage();}?>
以上例程的输出类似于:
Warning: SQLite3::exec(): near "foo": syntax error in example.php on line 4 Caught exception: near "bar": syntax error
