The capabilities of this DB implementation

The 'new_link' element contains the PHP version that first provided new_link support for this DBMS. Contains false if it's unsupported.

Meaning of the 'limit' element:

'emulate' = emulate with fetch row by number

Method Detail

__construct (Constructor) [line 147]

void __construct(
)

This constructor calls parent::__construct()

Overrides DB_common::__construct() (This constructor calls $this->PEAR('DB_Error'))

[ Top ]

connect [line 202]

int connect(
array
$dsn, [bool
$persistent = false])

Connect to the database and create it if it doesn't exist

Don't call this method directly. Use DB::connect() instead.

PEAR DB's dbase driver supports the following extra DSN options:

mode An integer specifying the read/write mode to use (0 = read only, 1 = write only, 2 = read/write). Available since PEAR DB 1.7.0.
fields An array of arrays that PHP's dbase_create() function needs to create a new database. This information is used if the dBase file specified in the "database" segment of the DSN does not exist. For more info, see the PHP manual's dbase_create() page. Available since PEAR DB 1.7.0.

Example of how to connect and establish a new dBase file if necessary:

 require_once 'DB.php';

 $dsn = array(
   'phptype' => 'dbase',
   'database' => '/path/and/name/of/dbase/file',
   'mode'   => 2,
   'fields'  => array(
     array('a', 'N', 5, 0),
     array('b', 'C', 40),
     array('c', 'C', 255),
     array('d', 'C', 20),
   ),
 );
 $options = array(
   'debug'    => 2,
   'portability' => DB_PORTABILITY_ALL ,
 );

 $db = DB ::connect ($dsn, $options);
 if (PEAR::isError($db)) {
   die($db->getMessage());
 }

Return: DB_OK on success. A DB_Error object on failure.

Parameters:

array $dsn — the data source name

bool $persistent — should the connection be persistent?

[ Top ]

disconnect [line 262]

bool disconnect(
)

Disconnects from the database server

Return: TRUE on success, FALSE on failure

[ Top ]

fetchInto [line 303]

mixed fetchInto(
resource
$result, 
&$arr, int
$fetchmode, [int
$rownum = null], array
$arr)

Places a row from the result set into the given array

Formating of the array and the data therein are configurable. See DB_result::fetchInto() for more information.

This method is not meant to be called directly. Use DB_result::fetchInto() instead. It can't be declared "protected" because DB_result is a separate object.

Return: DB_OK on success, NULL when the end of a result set is reached or on failure
See: DB_result::fetchInto()

Parameters:

resource $result — the query result resource

array $arr — the referenced array to put the data in

int $fetchmode — how the resulting array should be indexed

int $rownum — the row number to fetch (0 = first row)

&$arr —

[ Top ]

freeResult [line 343]

bool freeResult(
resource
$result)

Deletes the result set and frees the memory occupied by the result set.

This method is a no-op for dbase, as there aren't result resources in the same sense as most other database backends.

Return: TRUE on success, FALSE if $result is invalid
See: DB_result::free()

Parameters:

resource $result — PHP's query result resource

[ Top ]

numCols [line 364]

int numCols(
$foo, resource
$result)

Gets the number of columns in a result set

This method is not meant to be called directly. Use DB_result::numCols() instead. It can't be declared "protected" because DB_result is a separate object.

Return: the number of columns. A DB_Error object on failure.
See: DB_result::numCols()

Parameters:

resource $result — PHP's query result resource

$foo —

[ Top ]

numRows [line 385]

int numRows(
$foo, resource
$result)

Gets the number of rows in a result set

This method is not meant to be called directly. Use DB_result::numRows() instead. It can't be declared "protected" because DB_result is a separate object.

Return: the number of rows. A DB_Error object on failure.
See: DB_result::numRows()

Overrides DB_common::numRows() (Determines the number of rows in a query result)

Parameters:

resource $result — PHP's query result resource

$foo —

[ Top ]

query [line 272]

void &query(
[
$query = null])

Overrides DB_common::query() (Sends a query to the database server)

Parameters:

$query —

[ Top ]

quoteBoolean [line 402]

string quoteBoolean(
boolean
$boolean)

Formats a boolean value for use within a query in a locale-independent manner.

Return: the quoted string.
See: DB_common::quoteSmart()
Since: Method available since release 1.7.8.

Overrides DB_common::quoteBoolean() (Formats a boolean value for use within a query in a locale-independent manner.)

Parameters:

boolean $boolean — the boolean value to be quoted.

[ Top ]

tableInfo [line 422]

array tableInfo(
[mixed
$result = null], [int
$mode = null])

Returns information about the current database

Return: an associative array with the information requested. A DB_Error object on failure.
See: DB_common::tableInfo()
Since: Method available since Release 1.7.0

Overrides DB_common::tableInfo() (Returns information about a table or a result set)

Parameters:

mixed $result — THIS IS UNUSED IN DBASE. The current database is examined regardless of what is provided here.

int $mode — a valid tableInfo mode
