SQLITE_OPEN(3)															    SQLITE_OPEN(3)

sqlite_open - Opens an SQLite database and create the database if it does not exist

SYNOPSIS

       resource sqlite_open (string  $filename, [int  $mode = 0666], [string  &$error_message])

DESCRIPTION

       Object oriented style (constructor): SQLiteDatabase::__construct (string  $filename, [int  $mode = 0666], [string  &$error_message])

	Opens an SQLite database or creates the database if it does not exist.

PARAMETERS

	      o $filename
		-  The	filename of the SQLite database. If the file does not exist, SQLite will attempt to create it. PHP must have write permis-
		sions to the file if data is inserted, the database schema is modified or to create the database if it does not exist.

	      o $mode
		- The mode of the file. Intended to be used to open the database in read-only mode. Presently, this parameter is  ignored  by  the
		sqlite library. The default value for mode is the octal value 0666 and this is the recommended value.

	      o $error_message
		-  Passed by reference and is set to hold a descriptive error message explaining why the database could not be opened if there was
		an error.

RETURN VALUES

	Returns a resource (database handle) on success, FALSE on error.

EXAMPLES

       Example #1

	      sqlite_open(3) example

	      <?php
	      if ($db = sqlite_open('mysqlitedb', 0666, $sqliteerror)) {
		  sqlite_query($db, 'CREATE TABLE foo (bar varchar(10))');
		  sqlite_query($db, "INSERT INTO foo VALUES ('fnord')");
		  $result = sqlite_query($db, 'select bar from foo');
		  var_dump(sqlite_fetch_array($result));
	      } else {
		  die($sqliteerror);
	      }
	      ?>

NOTES

       Tip

	       On Unix platforms, SQLite is sensitive to scripts that use the fork() system call. If you do have such a script, it is  recommended
	      that  you  close the handle prior to forking and then re-open it in the child and/or parent. For more information on this issue, see
	      The C language interface to the SQLite library in the section entitled Multi-Threading And SQLite.

       Tip

	       It is not recommended to work with SQLite databases mounted on NFS partitions. Since NFS is notoriously bad when it comes to  lock-
	      ing you may find that you cannot even open the database at all, and if it succeeds, the locking behaviour may be undefined.

       Note

	       Starting  with  SQLite library version 2.8.2, you can specify :memory: as the $filename to create a database that lives only in the
	      memory of the computer. This is useful mostly for temporary processing, as the in-memory database will be destroyed when the process
	      ends.  It  can  also  be	useful when coupled with the ATTACH DATABASE SQL statement to load other databases and move and query data
	      between them.

       Note

	       SQLite is safe mode and open_basedir aware.

SQLITE_FETCH_COLUMN_TYPES(3)											      SQLITE_FETCH_COLUMN_TYPES(3)

sqlite_fetch_column_types - Return an array of column types from a particular table

SYNOPSIS

       array sqlite_fetch_column_types (string	$table_name, resource  $dbhandle, [int	$result_type = SQLITE_ASSOC])

DESCRIPTION

       Object oriented style (method): array SQLiteDatabase::fetchColumnTypes (string  $table_name, [int  $result_type = SQLITE_ASSOC])

       sqlite_fetch_column_types(3) returns an array of column data types from the specified $table_name table.

PARAMETERS

	      o $table_name
		- The table name to query.

	      o $dbhandle
		- The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the
		object-oriented method.

	      o $result_type
		- The optional $result_type parameter accepts a constant and determines how the returned array will be indexed. Using SQLITE_ASSOC
		will  return  only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers).
		SQLITE_ASSOC is the default for this function.

RETURN VALUES

	Returns an array of column data types; FALSE on error.

       The column names returned by SQLITE_ASSOC and SQLITE_BOTH will be case-folded according to the value of the sqlite.assoc_case configuration
       option.

EXAMPLES

       Example #1

	      Procedural example

	      <?php
	      $db = sqlite_open('mysqlitedb');
	      sqlite_query($db, 'CREATE TABLE foo (bar varchar(10), arf text)');
	      $cols = sqlite_fetch_column_types('foo', $db, SQLITE_ASSOC);

	      foreach ($cols as $column => $type) {
		  echo "Column: $column  Type: $type
";
	      }
	      ?>

       Example #2

	      Object-oriented example

	      <?php
	      $db = new SQLiteDatabase('mysqlitedb');
	      $db->query('CREATE TABLE foo (bar varchar(10), arf text)');
	      $cols = $db->fetchColumnTypes('foo', SQLITE_ASSOC);

	      foreach ($cols as $column => $type) {
		  echo "Column: $column  Type: $type
";
	      }
	      ?>

	      The above example will output:

	      Column: bar  Type: VARCHAR
	      Column: arf  Type: TEXT
