SQLite3::enableExceptions — Enable throwing exceptions
$enableExceptions = false
] )Controls whether the SQLite3 instance will throw exceptions or warnings on error.
enable
When 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.
Returns the old value; TRUE if exceptions were enabled, FALSE otherwise.
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
