例1 cubrid_bind() example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$result = cubrid_execute($conn, "SELECT code FROM event WHERE sports='Basketball' and gender='M'");
$row = cubrid_fetch_array($result, CUBRID_ASSOC);
$event_code = $row["code"];
cubrid_close_request($result);
$game_req = cubrid_prepare($conn, "SELECT athlete_code FROM game WHERE host_year=1992 and event_code=? and nation_code='USA'");
cubrid_bind($game_req, 1, $event_code, "number");
cubrid_execute($game_req);
printf("--- Dream Team (1992 United States men's Olympic basketball team) ---\n");
while ($athlete_code = cubrid_fetch_array($game_req, CUBRID_NUM)) {
$athlete_req = cubrid_prepare($conn, "SELECT name FROM athlete WHERE code=? AND nation_code='USA' AND event='Basketball' AND gender='M'");
cubrid_bind($athlete_req, 1, $athlete_code[0], "number");
cubrid_execute($athlete_req);
$row = cubrid_fetch_assoc($athlete_req);
printf("%s\n", $row["name"]);
}
cubrid_close_request($game_req);
cubrid_close_request($athlete_req);
cubrid_disconnect($conn);
?>
上の例の出力は以下となります。

例2 cubrid_bind() BLOB/CLOB example
<?php
$con = cubrid_connect("localhost", 33000, "foo");
if ($con) {
$sql = "INSERT INTO php_cubrid_lob_test(doc_content) VALUES(?)";
$req = cubrid_prepare($con, $sql);
$fp = fopen("book.txt", "rb");
cubrid_bind($req, 1, $fp, "blob");
cubrid_execute($req);
}
