Examples
Example #1 Setting and retrieving parameters through a connection resource
<?php
/* Database Connection Parameters */
$database = 'SAMPLE';
$user = 'db2inst1';
$password = 'ibmdb2';
/* Obtain Connection Resource */
$conn = db2_connect($database, $user, $password);
echo "Client attributes passed through connection string:\n";
/* Create the associative options array with valid key-value pairs */
/* Assign the attributes through connection string */
/* Access the options specified */
$options1 = array('userid' => 'db2inst1');
$conn1 = db2_connect($database, $user, $password, $options1);
$val = db2_get_option($conn1, 'userid');
echo $val . "\n";
$options2 = array('acctstr' => 'account');
$conn2 = db2_connect($database, $user, $password, $options2);
$val = db2_get_option($conn2, 'acctstr');
echo $val . "\n";
$options3 = array('applname' => 'myapp');
$conn3 = db2_connect($database, $user, $password, $options3);
$val = db2_get_option($conn3, 'applname');
echo $val . "\n";
$options4 = array('wrkstnname' => 'workstation');
$conn4 = db2_connect($database, $user, $password, $options4);
$val = db2_get_option($conn4, 'wrkstnname');
echo $val . "\n";
echo "Client attributes passed post-connection:\n";
/* Create the associative options array with valid key-value pairs */
/* Assign the attributes after a connection is made */
/* Access the options specified */
$options5 = array('userid' => 'db2inst1');
$conn5 = db2_connect($database, $user, $password);
$rc = db2_set_option($conn5, $options5, 1);
$val = db2_get_option($conn5, 'userid');
echo $val . "\n";
$options6 = array('acctstr' => 'account');
$conn6 = db2_connect($database, $user, $password);
$rc = db2_set_option($conn6, $options6, 1);
$val = db2_get_option($conn6, 'acctstr');
echo $val . "\n";
$options7 = array('applname' => 'myapp');
$conn7 = db2_connect($database, $user, $password);
$rc = db2_set_option($conn7, $options7, 1);
$val = db2_get_option($conn7, 'applname');
echo $val . "\n";
$options8 = array('wrkstnname' => 'workstation');
$conn8 = db2_connect($database, $user, $password);
$rc = db2_set_option($conn8, $options8, 1);
$val = db2_get_option($conn8, 'wrkstnname');
echo $val . "\n";
?>
The above example will output:
Client attributes passed through connection string: db2inst1 account myapp workstation Client attributes passed post-connection: db2inst1 account myapp workstation
