  • conn_identifier : Connection identifier
Return Value
  • Success : TRUE
  • Failure : FALSE
Example

<?php

$conn = cubrid_connect("127.0.0.1", 33000, "demodb");

 

@cubrid_execute($conn, "DROP TABLE publishers");

 

$sql = <<EOD

CREATE TABLE publishers(

pub_id CHAR(3),

pub_name VARCHAR(20),

city VARCHAR(15),

state CHAR(2),

country VARCHAR(15)

)

EOD;

 

if (!cubrid_execute($conn, $sql)) {

    printf("Error facility: %d Error code: %d Error msg: %s ", cubrid_error_code_facility(), cubrid_error_code(), cubrid_error_msg());

 

    cubrid_disconnect($conn);

    exit;

}

 

$req = cubrid_prepare($conn, "INSERT INTO publishers VALUES(?, ?, ?, ?, ?)");

 

$id_list = array("P01", "P02", "P03", "P04");

$name_list = array("Abatis Publishers", "Core Dump Books", "Schadenfreude Press", "Tenterhooks Press");

$city_list = array("New York", "San Francisco", "Hamburg", "Berkeley");

$state_list = array("NY", "CA", NULL, "CA");

$country_list = array("USA", "USA", "Germany", "USA");

 

for ($i = 0, $size = count($id_list); $i < $size; $i++) {

    cubrid_bind($req, 1, $id_list[$i]);

    cubrid_bind($req, 2, $name_list[$i]);

    cubrid_bind($req, 3, $city_list[$i]);

    cubrid_bind($req, 4, $state_list[$i]);

    cubrid_bind($req, 5, $country_list[$i]);

 

    if (!($ret = cubrid_execute($req))) {

        break;

    }

}

 

if (!$ret) {

    cubrid_rollback($conn);

} else {

    cubrid_commit($conn);

 

    $req = cubrid_execute($conn, "SELECT * FROM publishers");

    while ($result = cubrid_fetch_assoc($req)) {

        printf("%-3s %-20s %-15s %-3s %-15s ",

            $result["pub_id"], $result["pub_name"], $result["city"], $result["state"], $result["country"]);

    }

}

 

cubrid_disconnect($conn);

?>

 

The above example will output:

 

P01 Abatis Publishers    New York        NY  USA            

P02 Core Dump Books      San Francisco   CA  USA            

P03 Schadenfreude Press  Hamburg             Germany        

P04 Tenterhooks Press    Berkeley        CA  USA
