#124 [PHP]Return value is not false when passing a not-numeric value to cubrid_set_query_timeout method

[Jira Trac]

Test Build: CUBRID 2008 R4.1 (8.4.1.1018) (64bit release build for linux_gnu)
OS: Linux 64
Description:
Passing '20ii' to [cubrid_set_query_timeout|http://www.php.net/manual/en/function.cubrid-set-query-timeout.php] method, return value is not false.
and using cubrid_get_query_timeout method will get the value and the value is 20.

Repro steps:
1. execute time_test2.phpt
statements in time_test2.phpt
{noformat}
$host = localhost;
$port = 33113;
$db = demodb;
$conn = cubrid_connect_with_url(CUBRID:$host:$port:$db:::?login_timeout=5000query_timeout=5000disconnect_on_query_timeout=yes);
cubrid_execute($conn, DROP TABLE if exists timeout2_tb);
cubrid_execute($conn, create table timeout2_tb(id int, name varchar(10)));
cubrid_execute($conn, insert into timeout2_tb values(1,'nameq'),(2,'name2'),(3,'name3'));
$req1 = cubrid_execute($conn, SELECT * FROM timeout2_tb);
$set7=cubrid_set_query_timeout($req1,'10');
if(FALSE == $set7){
printf([007]Expect false,[%d] [%d] [%s]\n,cubrid_error_code_facility(), cubrid_errno($conn), cubrid_error($conn));
}else{
$timeout7 = cubrid_get_query_timeout($req1);
printf([007]timeout: %d\n,$timeout7);
}

$set10=cubrid_set_query_timeout($req1,'20ii');
if(FALSE == $set10){
printf([0010]Expect false,[%d] [%d] [%s]\n,cubrid_error_code_facility(), cubrid_errno($conn), cubrid_error($conn));
}else{
$timeout10 = cubrid_get_query_timeout($req1);
printf([0010]timeout: %d\n,$timeout10);
}
cubrid_close_prepare($req1);
cubrid_disconnect($conn);
{noformat}

Actual result:
{noformat}
[007]timeout: 10
PHP Notice: A non well formed numeric value encountered in /home/php/phpTestcases/_06_commit/bug/time_test2.phpt on line 20
[0010]timeout: 20
{noformat}

Expect resutl:
Maybe the return value will be false when the passing value is not int type.
