PHP - Integer Define ;s

Hi all,
 
I was reading a bit in the manual about the defined function. Since i have seen it being used quite a lot to disallow direct access. But one of the comments made me think if there are any alternatives to get the same.
it's this comment: http://www.php.net/manual/en/function.defined.php#89886

If i read it correct it tells that defined() seems to be pretty slow. I was thinking, if that is the case what are the alternatives...

Does anyone know how to interpret this comment and if there are alternatives? I am not yet a guru tofully understand the results.

cheers!

In many cases, variable have to be explicitly defined for whatever reason.

However, often it is not required for a simple web page script.

Yet, even in those cases, if a variable is NOT explicitly defined, the web server error log (example: my_domain.com-error_log) will rack up a lot of entries such as this: Quote

[Fri Dec 31 01:31:43 2010] [error] [client 123.123.123.123] PHP Notice:  Undefined variable: some_variable_name in /home/my_domain/public_html/some_page.php on line 6


A busy site could result in large error logs...

What is considered "best practice"? Should all variables always be explicitly defined with the var key word?

So I am trying to take a string value of dollars (posted from a form) and times it by 100 to get the cents Integer value of the dollars.  For some reason if I do this with something like 278.53  I end up with 27852.  Same concept for 278.59 ends up as 27858.  I don't understand why or how to make it work.  I've tried many things and nothing has made it work.

$price = '278.53'; // posted from the form
$cents = $price * 100; // converting to cents.
end_result = (int)$cents // This will end up being 27852 not 27853.

 

I want to round off an integer vaule to 10-6 grd from

52.71666666  to  52716666

0.926888888  to  926888

does anyone know a simple way to do this?

Hi Guys!

I have a method that get's all devices that share a specific ID. Foreach of those device UID's, I am trying to send a APN (Apple Push Notification) using the easyAPN's class.

The method that is having the problem is $apns->newMessage($id);

It seems to think I am not passing a valid integer for $id.

The $id is an array like so Array ( => 1 )

I have also tried passing just the value of the array like so $apns->newMessage($id[0]).

No matter what I do.. I keep getting this error...

"Notice: TO id was not an integer. 1) Messages_model::send_apns -> File: sendMessage.php (line 28) 2) APNS::queueMessage -> File: messages_model.php (line 195) 3) APNS::_triggerError -> File: class_APNS.php (line 599)"

Here is my method... please let me know where I've gone wrong with the $id.

function send_apns($data)
{
include 'apn_classes/class_DbConnect.php';
include 'apn_classes/class_APNS.php';

$message = new Messages_model();
$db = new DbConnect();
$db->show_errors();
$apns = new APNS($db);

//get uid's for aid
$sql = "SELECT `devices`.`uid` FROM `devices` WHERE `devices`.`aid` = '".$data['target']."'";
//echo $sql;
$query = mysql_query($sql);
if(mysql_num_rows($query))
{
while($uid_data = mysql_fetch_array($query))
$uids[] = array(
"uid" => $uid_data['uid']
);
}

//make sure there is a uid
if(!empty($uids))
{
//check the device apn pid
foreach($uids as $uid)
{
$sql = "SELECT `apns_devices`.`pid` FROM `apns_devices` WHERE `apns_devices`.`deviceuid` = '".$uid['uid']."'";
//echo "$sql";
$query = mysql_query($sql);
if(mysql_num_rows($query) > 0)
{
while($pid_data = mysql_fetch_array($query))
{
$pids[] = array(
"pid" => $pid_data['pid'],
);

if(!empty($pids))
{
foreach ($pids as $pid)
{
$id = array($pid['pid']);
print_r($id);
//Send APN
$apns->newMessage($id[0]);
$apns->addMessageBadge(128);
$apns->addMessageAlert($data['message']);
$apns->addMessageSound('chime');
//$apns->addMessageCustom('acme2');
$apns->queueMessage();
$apns->processQueue();
}
}
}
}
}

}
else 
{
echo "Device Does not Exist";
}
