IBASE_CONNECT(3) 1 IBASE_CONNECT(3) ibase_connect - Open a connection to a database SYNOPSIS
resource ibase_connect ([string $database], [string $username], [string $password], [string $charset], [int $buffers], [int $dialect], [string $role], [int $sync]) DESCRIPTION
Establishes a connection to an Firebird/InterBase server. In case a second call is made to ibase_connect(3) with the same arguments, no new link will be established, but instead, the link identi- fier of the already opened link will be returned. The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling ibase_close(3). PARAMETERS
o $database - The $database argument has to be a valid path to database file on the server it resides on. If the server is not local, it must be prefixed with either 'hostname:' (TCP/IP), 'hostname/port:' (TCP/IP with interbase server on custom TCP port), '//hostname/' (NetBEUI), depending on the connection protocol used. o $username - The user name. Can be set with the ibase.default_user php.ini directive. o $password - The password for $username. Can be set with the ibase.default_password php.ini directive. o $charset -$charset is the default character set for a database. o $buffers -$buffers is the number of database buffers to allocate for the server-side cache. If 0 or omitted, server chooses its own default. o $dialect -$dialect selects the default SQL dialect for any statement executed within a connection, and it defaults to the highest one sup- ported by client libraries. o $role - Functional only with InterBase 5 and up. o $sync - RETURN VALUES
Returns an Firebird/InterBase link identifier on success, or FALSE on error. ERRORS
/EXCEPTIONS If you get some error like "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character sets" (this occurs when you try use some character with accents) when using this and after ibase_query(3) you must set the character set (i.e. ISO8859_1 or your current character set). EXAMPLES
Example #1 ibase_connect(3) example <?php $host = 'localhost:/path/to/your.gdb'; $dbh = ibase_connect($host, $username, $password); $stmt = 'SELECT * FROM tblname'; $sth = ibase_query($dbh, $stmt); while ($row = ibase_fetch_object($sth)) { echo $row->email, " "; } ibase_free_result($sth); ibase_close($dbh); ?> SEE ALSO

MYSQL_CONNECT(3) 1 MYSQL_CONNECT(3) mysql_connect - Open a connection to a MySQL Server SYNOPSIS
Warning This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include: omysqli_connect(3) o PDO::__construct resource mysql_connect ([string $server = ini_get("mysql.default_host")], [string $username = ini_get("mysql.default_user")], [string $password = ini_get("mysql.default_password")], [bool $new_link = false], [int $client_flags]) DESCRIPTION
Opens or reuses a connection to a MySQL server. o $server - The MySQL server. It can also include a port number. e.g. "hostname:port" or a path to a local socket e.g. ":/path/to/socket" for the localhost. If the PHP directive mysql.default_host is undefined (default), then the default value is 'localhost:3306'. In SQL safe mode, this parameter is ignored and value 'localhost:3306' is always used. o $username - The username. Default value is defined by mysql.default_user. In SQL safe mode, this parameter is ignored and the name of the user that owns the server process is used. o $password - The password. Default value is defined by mysql.default_password. In SQL safe mode, this parameter is ignored and empty password is used. o $new_link - If a second call is made to mysql_connect(3) with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned. The $new_link parameter modifies this behavior and makes mysql_connect(3) always open a new link, even if mysql_connect(3) was called before with the same parameters. In SQL safe mode, this parameter is ignored. o $client_flags - The $client_flags parameter can be a combination of the following constants: 128 (enable LOAD DATA LOCAL handling), MYSQL_CLIENT_SSL, MYSQL_CLIENT_COMPRESS, MYSQL_CLIENT_IGNORE_SPACE or MYSQL_CLIENT_INTERACTIVE. Read the section about "MySQL client constants" for further information. In SQL safe mode, this parameter is ignored. Returns a MySQL link identifier on success or FALSE on failure. +--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.5.0 | | | | | | | This function will generate an E_DEPRECATED | | | error. | | | | | 4.3.0 | | | | | | | Added the $client_flags parameter. | | | | | 4.2.0 | | | | | | | Added the $new_link parameter. | | | | +--------+---------------------------------------------------+ Example #1 mysql_connect(3) example <?php $link = mysql_connect('localhost', 'mysql_user', 'mysql_password'); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_close($link); ?> Example #2 mysql_connect(3) example using hostname:port syntax <?php // we connect to example.com and port 3307 $link = mysql_connect('example.com:3307', 'mysql_user', 'mysql_password'); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_close($link); // we connect to localhost at port 3307 $link = mysql_connect('127.0.0.1:3307', 'mysql_user', 'mysql_password'); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_close($link); ?> Example #3 mysql_connect(3) example using ":/path/to/socket" syntax <?php // we connect to localhost and socket e.g. /tmp/mysql.sock // variant 1: omit localhost $link = mysql_connect(':/tmp/mysql', 'mysql_user', 'mysql_password'); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_close($link); // variant 2: with localhost $link = mysql_connect('localhost:/tmp/mysql.sock', 'mysql_user', 'mysql_password'); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_close($link); ?> Note Whenever you specify "localhost" or "localhost:port" as server, the MySQL client library will override this and try to connect to a local socket (named pipe on Windows). If you want to use TCP/IP, use "127.0.0.1" instead of "localhost". If the MySQL client library tries to connect to the wrong local socket, you should set the correct path as "" in your PHP configuration and leave the server field blank. Note The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling mysql_close(3). Note You can suppress the error message on failure by prepending a @ to the function name. Note Error "Can't create TCP/IP socket (10106)" usually means that the variables_order configure directive doesn't contain character E. On Windows, if the environment is not copied the SYSTEMROOT environment variable won't be available and PHP will have problems load- ing Winsock. mysql_pconnect(3), mysql_close(3).
