This is an extension for the SQLite Embeddable SQL Database Engine. SQLite is a C library that implements an embeddable SQL database engine. Programs that link with the SQLite library can have SQL database access without running a separate RDBMS process.

SQLite is not a client library used to connect to a big database server. SQLite is the server. The SQLite library reads and writes directly to and from the database files on disk.

Note: For further information see the SQLite Website (


Read the INSTALL file, which comes with the package. Or just use the PEAR installer with "pear install sqlite". SQLite itself is already included, You do not need to install any additional software.

Windows users may download the DLL version of the SQLite extension here: (php_sqlite.dll).

Contact Information

Any questions about the extension should be asked on one of the PHP Mailing lists.


In order to have these functions available, you must compile PHP with SQLite support, or load the SQLite extension dynamically from your php.ini.

Resource Types

There are two resources used in the SQLite Interface. The first one is the database connection, the second one the result set.

Predefined Constants

The functions sqlite_fetch_array() and sqlite_current() use a constant for the different types of result arrays. The following constants are defined:

Table 1. SQLite fetch constants

SQLITE_ASSOC Columns are returned into the array having the fieldname as the array index.
SQLITE_BOTH Columns are returned into the array having both a numerical index and the fieldname as the array index.
SQLITE_NUM Columns are returned into the array having a numerical index to the fields. This index starts with 0, the first field in the result.

Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

Table 2. SQLite Configuration Options

For further details and definition of the PHP_INI_* constants see ini_set().

Here's a short explanation of the configuration directives.

sqlite.assoc_case int

Whether to use mixed case (0), upper case (1) or lower case (2) hash indexes.

This option is primarily useful when you need compatibility with other database systems, where the names of the columns are always returned as uppercase or lowercase, regardless of the case of the actual field names in the database schema.

The SQLite library returns the column names in their natural case (that matches the case you used in your schema). When sqlite.assoc_case is set to 0 the natural case will be preserved. When it is set to 1 or 2, PHP will apply case folding on the hash keys to upper- or lower-case the keys, respectively.

Use of this option incurrs a slight performance penalty, but is MUCH faster than performing the case folding yourself using PHP script.
