范例
下面是一个在PHP和CUBRID建立连接的简单的例子。本节将覆盖最基本和最显著的特性。下面的代码需要连接CUBRID数据库，这意味着 CUBRID服务和 CUBRID Broker已经运行。
下面用demodb数据库作为例子举例。默认在安装时就创建了。确认此数据库已经被创建。
Example #1 数据查询的例子
<html> <head> <meta http-equiv="content-type" content="text/html; charset=euc-kr"> </head> <body> <center> <table border=2> <?php /** * Set server information for CUBRID connection. host_ip is the IP * address where the CUBRID Broker is installed (localhost in this * example), and host_port is the port number of the CUBRID Broker. * The port number is the default given during the installation. * For details, see "Administrator's Guide." */ $host_ip = "localhost"; $host_port = 33000; $db_name = "demodb"; /** * Connect to CUBRID Server. Do not make the actual connection, but * only retain the connection information. The reason for not making * the actual connection is to handle transaction more efficiently * in the 3-tier architecture. */ $cubrid_con = @cubrid_connect($host_ip, $host_port, $db_name); if (!$cubrid_con) { echo "Database Connection Error"; exit; } ?> <?php $sql = "select sports, count(players) as players from event group by sports"; /** * Request the CUBRID Server for the results of the SQL statement. * Now make the actual connection to the CUBRID Server. */ $result = cubrid_execute($cubrid_con, $sql); if ($result) { /** * Get the column names from the result set created by the SQL query. */ $columns = cubrid_column_names($result); /** * Get the number of columns in the result set created by the SQL query. */ $num_fields = cubrid_num_cols($result); /** * List the column names of the result set on the screen. */ echo("<tr>"); while (list($key, $colname) = each($columns)) { echo("<td align=center>$colname</td>"); } echo("</tr>"); /** * Get the results from the result set. */ while ($row = cubrid_fetch($result)) { echo("<tr>"); for ($i = 0; $i < $num_fields; $i++) { echo("<td align=center>"); echo($row[$i]); echo("</td>"); } echo("</tr>"); } } /** * The PHP module in the CUBRID runs in a 3-tier architecture. Even when * calling SELECT for transaction processing, it is processed as a part * of the transaction. Therefore, the transaction needs to be rolled back * by calling commit or rollback even though SELECT was called for smooth * performance. */ cubrid_commit($cubrid_con); cubrid_disconnect($cubrid_con); ?> </body> </html>
Example #2 数据插入的例子
<html> <head> <meta http-equiv="content-type" content="text/html; charset=euc- kr"> </head> <body> <center> <table border=2> <?php /** * host_ip is the IP address where the CUBRID Broker is installed * host_port is the port number of the CUBRID Broker * db_name is the name of CUBRID Database */ $host_ip = "localhost"; $host_port = 33000; $db_name = "demodb"; $cubrid_con = @cubrid_connect($host_ip, $host_port, $db_name); if (!$cubrid_con) { echo "Database Connection Error"; exit; } ?> <?php $sql = "insert into olympic (host_year,host_nation,host_city," . "opening_date,closing_date) values (2008, 'China', 'Beijing'," . "to_date('08-08-2008','mm-dd- yyyy'),to_date('08-24-2008','mm-dd-yyyy')) ;" $result = cubrid_execute($cubrid_con, $sql); if ($result) { /** * Handled successfully, so commit. */ cubrid_commit($cubrid_con); echo("Inserted successfully "); } else { /** * Error occurred, so the error message is output and rollback is called. */ echo(cubrid_error_msg()); cubrid_rollback($cubrid_con); } cubrid_disconnect($cubrid_con); ?> </body> </html>
