DB2_CLOSE(3) 1 DB2_CLOSE(3) db2_close - Closes a database connection SYNOPSIS
bool db2_close (resource $connection) DESCRIPTION
This function closes a DB2 client connection created with db2_connect(3) and returns the corresponding resources to the database server. If you attempt to close a persistent DB2 client connection created with db2_pconnect(3), the close request is ignored and the persistent DB2 client connection remains available for the next caller. PARAMETERS
o $connection - Specifies an active DB2 client connection. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Closing a connection The following example demonstrates a successful attempt to close a connection to an IBM DB2, Cloudscape, or Apache Derby database. <?php $conn = db2_connect('SAMPLE', 'db2inst1', 'ibmdb2'); $rc = db2_close($conn); if ($rc) { echo "Connection was successfully closed."; } ?> The above example will output: Connection was successfully closed.

DB2_GET_OPTION(3) 1 DB2_GET_OPTION(3) db2_get_option - Retrieves an option value for a statement resource or a connection resource SYNOPSIS
string db2_get_option (resource $resource, string $option) DESCRIPTION
Retrieves the value of a specified option value for a statement resource or a connection resource. PARAMETERS
o $resource - A valid statement resource as returned from db2_prepare(3) or a valid connection resource as returned from db2_connect(3) or db2_pconnect(3). o $option - A valid statement or connection options. The following new options are available as of ibm_db2 version 1.6.0. They provide use- ful tracking information that can be set during execution with db2_get_option(3). Note Prior versions of ibm_db2 do not support these new options. When the value in each option is being set, some servers might not handle the entire length provided and might truncate the value. To ensure that the data specified in each option is converted correctly when transmitted to a host system, use only the characters A through Z, 0 through 9, and the underscore (_) or period (.). o $userid - SQL_ATTR_INFO_USERID - A pointer to a null-terminated character string used to identify the client user ID sent to the host database server when using DB2 Connect. Note DB2 for z/OS and OS/390 servers support up to a length of 16 characters. This user-id is not to be confused with the authentication user-id, it is for identification purposes only and is not used for any authorization. o $acctstr - SQL_ATTR_INFO_ACCTSTR - A pointer to a null-terminated character string used to identify the client accounting string sent to the host database server when using DB2 Connect. Note DB2 for z/OS and OS/390 servers support up to a length of 200 characters. o $applname - SQL_ATTR_INFO_APPLNAME - A pointer to a null-terminated character string used to identify the client application name sent to the host database server when using DB2 Connect. Note DB2 for z/OS and OS/390 servers support up to a length of 32 characters. o $wrkstnname - SQL_ATTR_INFO_WRKSTNNAME - A pointer to a null-terminated character string used to identify the client workstation name sent to the host database server when using DB2 Connect. Note DB2 for z/OS and OS/390 servers support up to a length of 18 characters.
