mysql_real_escape_string 函数无法启用 php是版本5

[QCB181]

Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: Access denied for user 'IUSR_CZIDC'@'localhost' (using password: NO) in E:\工作\企业模板\wwwroot\test.php on line 17

Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: A link to the server could not be established in E:\工作\企业模板\wwwroot\test.php on line 17

这样的语句出错

$str="123445676'";
print "<br>";
echo get_magic_quotes_gpc();
echo mysql_real_escape_string($str);

问题已经解决了
原来都是
sql.safe_mode=On

惹的祸，把 sql.safe_mode=Off

以上问题都解决了
