    SQLite3::__construct — Instantiates an SQLite3 object and opens an SQLite 3 database

    Description

    publicSQLite3::__construct(string$filename, int$flags = SQLITE3_OPEN_READWRITE | SQLITE3_OPEN_CREATE, string$encryptionKey = "")

    Instantiates an SQLite3 object and opens a connection to an SQLite 3 database. If the build includes encryption, then it will attempt to use the key.

    Parameters

    filename

    Path to the SQLite database, or :memory: to use in-memory database. If filename is an empty string, then a private, temporary on-disk database will be created. This private database will be automatically deleted as soon as the database connection is closed.

    flags

    Optional flags used to determine how to open the SQLite database. By default, open uses SQLITE3_OPEN_READWRITE | SQLITE3_OPEN_CREATE.

    • SQLITE3_OPEN_READONLY: Open the database for reading only.

    • SQLITE3_OPEN_READWRITE: Open the database for reading and writing.

    • SQLITE3_OPEN_CREATE: Create the database if it does not exist.

    encryptionKey

    An optional encryption key used when encrypting and decrypting an SQLite database. If the SQLite encryption module is not installed, this parameter will have no effect.

    Errors/Exceptions

    Throws an Exception on failure.

    Changelog

    VersionDescription
    7.0.10 The filename can now be empty to use a private, temporary on-disk database.
