PHP - Using Ceiling Or Round Function For Decimals Places

Here is the number:



$GrandTotal = "68.835";
$Deposit = round($GrandTotal , 2) * .5;

echo $Deposit;



I am looking for: 68.84 but the function doesn't seem to work right.

Any help?

Hi - To me, this doesn't make sense.   My Order form uploads product weights in an array . If I echo out those weights they are fine ie 25.25

However, when I try to update the DB for some reason, the for loop strips out all but the first digit, so 25.25 becomes '2' or indeed if I had entered 9999999 it just '9' is entered in to the DB.

I have tried using number_format to pre-process the decimals, - but I get an error saying you can not use it in a write format.

Many Thanks to anyone who can help with this  !!


PS - I have abbreviated the below code for clarity:

Code: [Select]
$weight = $_POST['weight'];

        for ($i = 0; $i < $numloops ; $i++)

      {
       $sql ="
UPDATE `confirmedorder`
SET orderid = '$orderid[$i]', weight='$weight[$i]',status='finished', ordervalue='$ordervalue'
WHERE customerid = $customerid
";
$this->db->query($sql);
}

Just looking to know if this is the proper way to implement this:

I need the below if to be true when any number between 100 and 1000 is the value of x, including say "105.55"

if($x>= 100 && $x <= 1000){
}


Basically I'm asking will a value of x with a decimal in it not cause the if statement to be true.

I want to find the first sentence in a string without counting decimals. Here is the code I have, but I still want it to display the decimals, but I don't want it to count as the end of a sentence.

$content = "This is my test string which is 3.5% of what I'm trying to do. This is only a test.";

Code: [Select]
function first_sentence($content)
 {
if(preg_match('/[0-9]+\.[0-9]/', $content, $num)) {
$number = "$num[0]";
$content = ereg_replace("$number","", $content);
}
preg_match('/^.*[^\s](\.|\?|\!)/U', $content, $match);
$string = $match[0];

$title_count = strlen($match[0]);
if($title_count > "6"){
return "$match[0]";
}
else {
$content2 = ereg_replace("$match[0]","", $content);
preg_match('/^.*[^\s](\.|\?|\!)/U', $content2, $step);
return "$match[0] $step[0]";
}}
Currently this is what it displays: This is my test string which is % of what I'm trying to do.
This is what I want it to display: This is my test string which is 3.5% of what I'm trying to do.

Ok so say I have php do some calculations for me

Code: [Select]

$Value1 = 300;
$Value2 = 100000;
$FirstRatio = $Value1 / $Value2;

$Value3 = 8000;
$Value4 = 6000000;
$SecondRatio = $Value3 / $Value4;


$FirstRatio = 0.003
$SecondRatio = 0.0013

How would I go about doing these calculations and then sorting $FirstRatio and $SecondRatio and then it would take the highest ratio ($FirstRatio) and it would echo the value?

For every search, I get ZERO RESULTS, and I don't understand what I'm doing wrong.

Code: [Select]
<?php
require('places_class.php');

$types = $_POST['type'];
$location = $_POST['place'];
$radius = $_POST['radius'];

$gplaces = New GooglePlaces;
$gplaces->SetLocation("$location");
$gplaces->SetRadius($radius);
$gplaces->SetTypes("$types");
$results = $gplaces->Search();

print_r($results);
?>

That's when the form is submitted, I checked the variables, and they are echoing out correctly.

Then I thought I'd hard-code the values in, same results
Code: [Select]
<?php
require('places_class.php');

$gplaces = New GooglePlaces;
$gplaces->SetLocation("40.5267,81.4778");
$gplaces->SetRadius(50);
$gplaces->SetTypes("food");
$results = $gplaces->Search();

print_r($results);
?>

And yes, I do have the correct API Key, I just took it out

Can anybody see what the issue is?

Hi, I'm trying to force 2 decimal places with the following function but it 's not working.  Any suggestions? 

Code: [Select]
function ShippingCost() {
$shippingCost = 4.00;
    number_format($shippingCost,2);
return $shippingCost;
}

how do i make a leaderboard that is capable of handling equal scores from a particular result?

we use following points allocations:
winner: 5pts
second: 3pts
third: 2pts
fourth: 1pt

however, if 2nd and 3rd have tied scores, i would like to combine their point allocations together and divide by 2, i.e. (3+2)/2=2.5points each.

initial query for competition ranking:

$q_lastcomp = "SELECT p.p_id, p.p_surname, p.p_forename, p.p_handicap, r.r_id, rp.rp_score, rp.rp_handicap, (rp.rp_score-rp.rp_handicap) as net_score ";
$q_lastcomp .= "FROM dan_roundplayed rp, dan_round r, dan_player p ";
$q_lastcomp .= "WHERE r.r_id = rp.rp_rid ";
$q_lastcomp .= "AND p.p_id = rp.rp_pid ";
$q_lastcomp .= "AND r.r_id = 6 ";
$q_lastcomp .= "ORDER BY net_score";
$r_lastcomp = mysql_query($q_lastcomp) or die(mysql_error());


i then loop through this resultset in this order (top down), and do some more calculations to adjust the players golf handicaps based on these results too. basically, if there are 4 players, the winner has beaten 3 others, second has beaten 2 others, down to last place who has beaten no-one.
the number of players you have beaten is multiplied by 10% of their handicap (not precisely this value, but something like it and makes easier to explain), then this adjustment is subtracted from the handicap to make a new handicap for the next comp.

this works fine, so long as no-one is tied. but if 2nd and 3rd tie, then both players have effectively only beaten 1 other player (last placed). so i would want both to do "hcap - (1*(hcap*0.1))" for their handicap adjustment calculations.
in my current code, even though they were tied, 2nd would have: "hcap - (2*(hcap*0.1))"
3rd would have: "hcap - (1*(hcap*0.1))"

my current loop code is:

    $total_players = mysql_num_rows($r_lastcomp);
    
    $i = 1;
    while($row = mysql_fetch_array($r_lastcomp)){
        echo "<br>";
        $round_hcap = round($row[p_handicap]);
        SWITCH ($round_hcap){
            CASE $round_hcap >= 0 AND $round_hcap <= 19:
                $multiplier = 0.1;
                break;
            CASE $round_hcap >= 20 AND $round_hcap <= 29:
                $multiplier = 0.2;
                break;
            CASE $round_hcap >= 30 AND $round_hcap <= 39:
                $multiplier = 0.3;
                break;
            CASE $round_hcap >= 40 AND $round_hcap <= 49:
                $multiplier = 0.4;
                break;
        }
        $hcap_reduce = ($total_players-$i)*$multiplier;
        $new_hcap = $row[p_handicap]-(($total_players-$i)*$multiplier);
        $sqlstr = "INSERT INTO dan_handicap VALUES (". $row[p_id]. ",". $row[r_id]. ",". $row[p_handicap]. ",". $i. ",";
        $sqlstr .= $total_players. ",". $hcap_reduce. ",". $new_hcap. ");";
        $sqlstr2 = "UPDATE dan_player SET p_handicap = ". $new_hcap. " WHERE p_id = ". $row[p_id]. ";";
        echo $sqlstr. "<br>";
        echo $sqlstr2. "<br>";
        $i++;
    }


can anyone help with this please?

my initial thoughts are i am going to need a drastic adjustment to the initial query add in position number in the comp, i.e. this would produce
posn | name | score
1 | winner | 10
2 | tied 2nd | 8
2 | tied 2nd | 8
4 | last place | 5

the second section of code could then use this "position number" for the multiplier part of the calculations.

apologies for the length of the post, but this covers the whole requirements.

i am echoing out a value which is 1.2900

but i want it to echo out 1.29
how do i do this?



cheers matt

Bascially i add a couple numbers up and display the sum.

sometimes the number is something like this: 234.237

i want it to display : 234.24

i realize its needs "round()" in it but i dont know how to use it..

any help?

Hey, just wondering what would be the best way of adding .1 to a string.

For example:

Code: [Select]
$newversion = $currentversion + '0.0.1';
$newversion is taken from a db, lets say for this example it is 0.2.1

This code simply outputs 0.2

Any ideas?

Thanks =)

hi know who to round a number to the nearest whole number,

if i use

echo round(9.5); it echo's 10
and if i use
echo round(9.2); it echo's 9

i want it so it always rounds up?

can anyone help?

cheers matt

hello guys, im creating a search result page that uses pagination, and im trying to figure out how many total pages their are going to be in my links with the page numbers. this is probably something really simple, ive been writing scripts for the last few hours and have a bit of a headache, any help would be appreciated here's the coding and the results i want:


<?php

$per_page = 10;
$rows = mysql_query("SELECT COUNT(*) FROM articles WHERE text LIKE $string"); // this will return 31
$pages = $rows / $per_page; // returns 3.1
$total_pages = round($pages); // returns 3, want to round 3.1 up to 4 here

?>

Hello

It's about exception handling...

I have two if statements, one inside the other. And I want to throw an exception from each, if one of them is FALSE. What "technique" should I use? I think throwing same exception with the same message within two if's is a bit messy.

like:
if $x is true
  //go to 2nd if:
  if $y is true
     return value
  if $y is false: throw exception "Invalid number"
if $x is false: throw exception "Invalid number"

Thanks,
