Hello,   I am fairly new to PHP and I found some php code to print an array of numbers that create a combination - however, its slams all the numbers together without a space or a comma separator.   How can I separate the numbers in this array with the given code?  Ive attached a photo of the code.

Hello im working on a project which involves marking attendance via an RFID tag and saving the time into an sql file. Everything seems to be working fine and the time stamp is successfully punched into the SQL but something is wrong with the php code thats supposed to display this data. Please if any one can take a look and help.

MY CODE for displaying the data (ViewAttendance.php):

<?php
include_once("header.php");
$attData = array();
$totDays = 0;
if(isset($_REQUEST['submit'])){
	$totDays = cal_days_in_month(CAL_GREGORIAN,$_REQUEST['month'],$_REQUEST['year']);
	$attData = $commonObj->getAttendanceData($_REQUEST['month'],$_REQUEST['year']);
	//print_r($attData);
	//print_r(date("d",strtotime($attData[0]['punch_time'])));
}
?>
