范例

Example #1 cubrid_field_flags() example


<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$result = cubrid_execute($conn, "SELECT * FROM game WHERE host_year=2004 AND nation_code='AUS' AND medal='G'");

$col_num = cubrid_num_cols($result);

printf("%-30s %s\n", "Field Name", "Field Flags");
for($i = 0; $i < $col_num; $i++) {
    printf("%-30s %s\n", cubrid_field_name($result, $i), cubrid_field_flags($result, $i)); 
}

cubrid_disconnect($conn);
?>
