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{|}~"
