PHP - Is_int Useage

Hi, I'm a newbie here, and with PHP, and need some help with the datetime display.
I am wanting to utilize old Naval comms DTG (datetimegroup) format which is DDHHMM 3-digit Month 2-digit year.
The DDHHMM = Day (01 - 31) HH (hour 01 - 24) MM (minute 00 - 59)
What I need to do is to add the letter Z (meaning GMT, ZULU) like thus  DDHHMMZ FEB 11
How can I go about inserting that Z into this?

Tks in advance for any assist

Hi,

I did a search for this function and found a similar post but wasn't able to understand it.

Presently I am just trying to do a simple test with the is_int function. I have it set up as follows:

Code: [Select]
if (is_int ($variable)) {
          echo 'Integer';
          } else {
          echo 'Not integer';
$variable is converted to a variable from some text on a web form.

I can see the problem here is that no matter what is entered on the web form, $variable is always a string. The code I referenced above works fine if I instead use the is_string function. I guess I'm just trying to figure out the following:

1. Why is it always a string, even when entering a number such as 7?
2. How can I overcome this so that I can check to make sure the input is of the correct type (integer)?

I know I'm probably not doing a good job of explaining what I mean but I think what I'm aiming to do should be clear; let me know if it isn't.


NOTE--I think I get this to a degree--anything passed in a form will be a string, is that correct? So I should be able to use is_numeric instead. However, the problem with that is that it would also return True for non-integers such as floats. I only want the user to be able to enter integers, 8.5 should return False in this case.

Thanks!

$showCountSql      =   "select cad_count from counteraccountdtl WHERE cad_userid =".$_SESSION['UID']." LIMIT 1";
$showCountresult    =    mysql_query($showCountSql);
$showCountrow      =    mysql_fetch_array($showCountresult);
$newCount      =   $showCountrow[cad_count];


if(is_int($newCount))
 echo "Value  is Integer";
else
 echo "Value not Integer";
