説明

function cubrid_real_escape_string(string $unescaped_string, resource $conn_identifier = ?): string

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 you want to include a single quote as part of a character string, enter two single quotes in a row.

<?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);
