I have this query:
$stmt=$dbh->prepare("select round((expire - unix_timestamp()) / 86400) as days, count(*) as cnt from xeon_users_rented WHERE user_by=:username group by days;");
$stmt->bindParam(":username",$userdata['username']);
$stmt->execute();
$data=$stmt->fetchAll();
Which returns this array result var_dump($data)
:
array(2) {
[0]=>
array(4) {
["days"]=>
string(2) "27"
[0]=>
string(2) "27"
["cnt"]=>
string(1) "2"
[1]=>
string(1) "2"
}
[1]=>
array(4) {
["days"]=>
string(3) "116"
[0]=>
string(3) "116"
["cnt"]=>
string(1) "8"
[1]=>
string(1) "8"
}
}
I then want to get the highest value of the $data
result:
echo max($data["days"]);
Althoug that doesn't work, as nothing is getting echoed out. What am I doing wrong?
