XCVII. SQLite

Introduction

   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
     (http://sqlite.org/).

Installation

   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.

Requirements

   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
   constant meaning
   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
   Name              Default Changeable
   sqlite.assoc_case 0       PHP_INI_ALL
   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 incurs a slight performance penalty, but is
          MUCH faster than performing the case folding yourself using PHP
          script.
