PHP Warning: "Division by zero"

[Natloy90]

Im running an online text based game and recently done some core edits. I've run into an error and can't seem to find the problem, the error im getting is:

 

^{PHP Warning: "Division by zero"}

^{in /home/f/i/firestorms/public_html/modules/healthbar.php at 52.}

^{Call Stack:}

^{2: healthbar_dohook("charstats", Array(}

 

    ^{"available"=>10, "used"=>0}

 

^{)) called from /home/f/i/firestorms/public_html/lib/modules.php on line 514}

^{5: page_footer() called from /home/f/i/firestorms/public_html/newday.php on line 323}

 

My code is:

 

^{function healthbar_dohook($hookname,$args){}

^{global $session;}

^{switch($hookname){}

^{case "charstats":}

^{if ($session['user']['alive']) {}

^{$cur = $session['user']['hitpoints'];}

^{$realmax = $session['user']['maxhitpoints'];}

^{$stat = "Hitpoints";}

^{$cur_adjustment = check_temp_stat("hitpoints",1);}

^{$max_adjustment = check_temp_stat("maxhitpoints",1);}

^{} else {}

^{$cur = $session['user']['soulpoints'];}

^{$realmax = $session['user']['level'] * 5 + 50;}

^{$stat = "Soulpoints";}

^{$cur_adjustment = check_temp_stat("soulpoints",1);}

^{$max_adjustment = "";}

^}

^{if ($cur > $realmax) $max = $cur;}

^{else $max = $realmax;}

 

^{$pct = round($cur / $max * 100, 0);}

^{$nonpct = 100-$pct;}

^{if ($pct > 100) {}

^{$pct = 100;}

^{$nonpct = 0;}

^}

^{if ($pct < 0) {}

^{$pct = 0;}

^{$nonpct = 100;}

^}

^{if ($pct > 60) {}

^{if ($session['user']['alive']) $color = "#00ff00";}

^{else $color = "#dddddd";}

^{$ccode = "`@";}

^{} elseif ($pct > 25) {}

^{if ($session['user']['alive']) $color = "#ffff00";}

^{else $color = "#666666";}

^{$ccode = "`^";}

^{} else {}

^{if ($session['user']['alive']) $color = "#ff0000";}

^{else $color = "#880000";}

^{$ccode = "`$";}

^}

^{$hicode = "`&";}

^{if (!$session['user']['alive']) {}

^{$ccode = "`7";}

^}

 

The Bold piece of the code is the line of 'error' ^{in /home/f/i/firestorms/public_html/modules/healthbar.php at 52.}

Appears that $cur and/or $max are the wrong data type.  Make sure that they are integers to use round.  You can use intval (http://ca.php.net/intval) to get the integer value of a string.

As it says on the tin - you are trying to divide by zero, so $max must be zero when it fails.
