説明
$unescaped_string
[, resource $conn_identifier

This function returns the escaped string version of the given string. It
will escape the following characters: '.
In general, single quotations are used to enclose character string. Double
quotations may be used as well depending on the value of ansi_quotes,
which is a parameter related to SQL statement. If the ansi_quotes value is

character string, not as an identifier. The default value is yes.
If you want to include a single quote as part of a character string, enter
two single quotes in a row.

例
例1 cubrid_real_escape_string() example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$unescaped_str = ' !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~';
$escaped_str = cubrid_real_escape_string($unescaped_str);
$len = strlen($unescaped_str);
@cubrid_execute($conn, "DROP TABLE cubrid_test");
cubrid_execute($conn, "CREATE TABLE cubrid_test (t char($len))");
cubrid_execute($conn, "INSERT INTO cubrid_test (t) VALUES('$escaped_str')");
$req = cubrid_execute($conn, "SELECT * FROM cubrid_test");
$row = cubrid_fetch_assoc($req);
var_dump($row);
cubrid_close_request($req);
cubrid_disconnect($conn);
?>
上の例の出力は以下となります。
array(1) {
["t"]=>
string(95) " !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~"
