SQLite3::enableExceptions

    (PHP 5 >= 5.3.0, PHP 7, PHP 8)

    SQLite3::enableExceptions — Enable throwing exceptions

    说明

    publicSQLite3::enableExceptions(bool$enable = false): bool

    Controls whether the SQLite3 instance will throw exceptions or warnings on error.

    参数

    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.

    返回值

    Returns the old value; true if exceptions were enabled, false otherwise.

    更新日志

    版本说明
    8.3.0 Calling SQLite3::enableExceptions() with enable as false will trigger a E_DEPRECATED warning.

    示例

    示例 #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();
    }
    ?>

    以上示例的输出类似于：

    Warning: SQLite3::exec(): near "foo": syntax error in example.php on line 4 Caught exception: near "bar": syntax error
