I am looking at displaying a text percentage amount. So if your life is a maximum of 1,000 and you currently have 200 health, it shows Health: 20%

Anyone know how I can take 0 to the max health number?

0 = 0%
1 = 1%
Max Health = 100%

and whatever in between. This would be a huge help, thank you.

Edit: By the way it'd be grabbing database values like $user['currenthealth'] and $user['maxhealth']

$percent_health = ($user['currenthealth']/$user['maxhealth'])*100;
echo $percent_health."%";


Is that what you were asking for?

Thanks for the reply. It didn't quite work, the result came to:

Current HP: 74.3726235741%

I am guessing that means 74%? Does it just need to be floored or is there a way to make sure it's always a solid number with no decimals?

Then round the value.

You can use three different things to get that to the way you want it. Using ceil or floor functions or round.


// ceil function
// this rounds everything up
$percent_health = ceil(($user['currenthp']/$user['maxhp'])*100);
echo $percent_health."%";

//floor function
// this rounds everything down
$percent_health = floor(($user['currenthp']/$user['maxhp'])*100);
echo $percent_health."%";

// round
// this rounds anything <5 down and anything >= 5 up
$percent_health = round(($user['currenthp']/$user['maxhp'])*100);
echo $percent_health."%";

My health should only be in the 70's but it's saying 100% so it isn't right. I tried round and ceil both.

$percent_health = ceil(($user['currenthp']/$user['maxhp']))*100;

That is because you have your parentheses wrong. You need to copy it like I have it. See if that works.

Good catch! I missed that.
