Take average of array

[christo16]

Hello all, I am trying to take an average of the difference of two different numbers in a mysql row.  What I did is output them into an array but when I do sum_array(array) it out puts to zero.  Any ideas where I went wrong?

 

$result = mysql_query('SELECT * FROM requests WHERE reqtime >= "'.$date.'" AND status = "ready" OR status = "pu"');
while ($row = mysql_fetch_array($result)) {
//Converts to unix time
$reqstamp = strtotime($row[1]);
$rfpstamp = strtotime($row[61]);
//Finds amt of time between begin and end
$difference = $rfpstamp - $reqstamp;
$tat = $difference /60/60/24; //Converts seconds to days
$tat= round($tat, 3); //Rounds to 2 decimal places

print "Total Turn Around Time: ".$tat."<br>";

print "<br><br>";
//adds the turn around time to the array
$tat_array[] = array($tat);
}

print array_sum($tat_array);

You're creating a two-dimensioned array, where you only want a normal array. Change this:

<?php
$tat_array[] = array($tat);
?>

to

<?php
$tat_array[] = $tat;
?>
