Age counter only counting years

Hi experts,

In my site I've got two age counters in a loop but they only count the years.

For example someone with birth date 2003-9-30 will be precented as a 7 years old person.
But he should be precented as a 6 year old. What should I change in my current code set this right?

Thanks

<?php
if(!isset($_POST['team'])){header("Location: samenstellen_keuze.php");} 
include('../includes/config.php'); 
access_control();

if(isset($_GET['moveto'])){$type = $_GET['moveto'];
	if ($type == "right"){
		if(isset($_POST['moveright'])){
			$moveright_array = $_POST['moveright'];
			foreach($moveright_array as $value1){
			  $sql="INSERT INTO functies (functietype, groepsID, persoonsID) VALUES ('41', '{$_POST['team']}', '$value1')";
			  $Result1 = mysql_query($sql,$con)or die(mysql_error());
			}
		unset($_POST['moveright']);
		}
	}
	if ($type == "left"){
		if(isset($_POST['moveleft'])){
			$moveleft_array = $_POST['moveleft'];
			foreach($moveleft_array as $value2){
	  		  	mysql_select_db($database, $con);
			  	$sql="delete from functies where functietype = '41' AND groepsID = '{$_POST['team']}' AND persoonsID = '$value2'";
			  	$Result1 = mysql_query($sql,$con)or die(mysql_error());
			}
		unset($_POST['moveleft']);  
		}
	}

Can't quite follow your code, but here is a teaching example of how to get the age on a given date.

HTH, ~Ray
<?php // RAY_age_on_date.php
error_reporting(E_ALL);

// A FUNCTION TO RETURN THE AGE ON A GIVEN DATE
function age_group($birth_date, $test_date='Today')
{
    // IF THE DATE IS NOT USABLE
    if (!$timestamp = strtotime($birth_date)) return FALSE;
    if (!$teststamp = strtotime($test_date))  return FALSE;

    // GET THE YEAR AND SUBTRACT FROM THIS YEAR
    $year_birth = date('Y', $timestamp);
    $year_now   = date('Y', $teststamp);
    $years_elapsed = $year_now - $year_birth - 1;

    // GET THE MONTH AND DAY IN THE STYLE OF ISO8601 DATES
    $moday_birth = date('m-d', $timestamp);
    $moday_cut   = date('m-d', $teststamp);

    // IF THE BIRTHDAY IS BEFORE CUTOFF ADD ONE YEAR
    if ($moday_birth <= $moday_cut) $years_elapsed++;

    return $years_elapsed;
}


// TEST DATA
echo "<pre>";

// A BIRTHDAY
$dt = date('Y-m-d', strtotime('tomorrow'));

// COUNT BACKWARDS FOR EACH BIRTHDAY
while ($dt > '1990-05-01')
{
    echo "\nA CHILD BORN ON " . $dt; echo " WILL BE AGE " . age_group($dt) . " TODAY";
    $dt = date('Y-m-d', strtotime($dt . ' - 1 day'));
}
