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

?>

This works
echo $data3['value'];

But this doesn't
echo round($data3['value'], 2);

Can someone please advise me as to what I am doing wrong?

Code: [Select]
$newrating = round($imageinfo['rating'],2);
this outputs:

4.49

in my db rating is

4.4884   


all i need is the 4.... would i use some type of preg_replace or something just to grab the first 1 before the decimal? (all  i need is the first number before the decimal)

I need to take a time and convert so it is rounded up or down to the nearest 0 or 5.

Code: [Select]
function roundMe ($time, $upDown) {

  if($upDown==1) {
     //round up
  } else {
     //round down
  }

  return $x;

}

echo roundMe("16:22", 1); // returns 16:25
echo roundMe("16:22", 0); // returns 16:20
echo roundMe("16:25", 1); // returns 16:25
echo roundMe("16:59", 1); // returns 17:00
echo roundMe("16:59", 0); // returns 16:55

I am trying to output only 40 of the latest files uploaded on the database server.

But when I am trying to see the files uploaded on the server I am getting this error:

Warning: round() expects parameter 2 to be long, string given in C:\wamp\www\mshare\lista.php on line 8 Call Stack

The code:
Code: [Select]
<?php

function bytestostring($size, $precision = 0) {
    $sizes = array('YB', 'ZB', 'EB', 'PB', 'TB', 'GB', 'MB', 'kB', 'B');
    $total = count($sizes);

    while($total-- && $size > 1024) $size /= 1024;
    return round($size, $precision)." ".$sizes[$total];
}




echo '<div class="header">40 last uploaded files:</div>';


$sql = "SELECT * FROM filer order by id desc limit 40";
$q = mysql_query($sql);

echo '<table style="width: 100%;">';

while ($r = mysql_fetch_array($q)) {

$i++;

$id = $r['id'];
$filnamn = $r['name'];
$filtyp = explode("/", $r['type']);
$filtyp = ucwords($filtyp[0]);
if($filtyp == "") {
$filtyp = "Unkown";
}
$filstorlek = bytestostring($r['size'], "");

$a = $i%2; 

echo'<tr><td class="lista">';

I am new to PHP coding so you guys just know.

i have a price i want to add 10%-15% to the base price and that the result

will be rounded to 9 in the ones digit place.

for example

85 +15%=97.7
$result=99

117+15%=134.55
$result = 139

played with round() and ceil()

Hi..

I encountered problem in rounding of numbers into two decimal places.

here is my sample code:


if($W4_STATUS == 1 AND $DEPENDENTS == 0 AND $TotEarn >= 7917 AND $TotEarn <= 12500) {
   $TAX = ($TotEarn - 7917);
   $TAX = (937.50 + ($TAX * .25));
   $TAX = number_format($TAX, 2, '.', '');
}


for example from this:

 $TAX = ($TotEarn - 7917);
  $TAX = (937.50 + ($TAX * .25));

the output is: 1417.615

using this:

$TAX = number_format($TAX, 2, '.', '');

the output was : 1417.61

but it should be : 1417.62

Thank you

Hey guys,

hello, if i have the following, how would i display it?

Code: [Select]
function minutes_round ($hour = "$signintime", $minutes = '5', $format = "H:i")
{
    $seconds = strtotime($hour);
    $rounded = round($seconds / ($minutes * 60)) * ($minutes * 60);
    return date($format, $rounded);
}

Hi there.

I am trying to display numbers if they have the numbers like:

number_format($price,2)

This gives us two decimal places i.e 7.23

Now thats fine, I would like to round the last two decimal places. I would like to make it 7.25, (rounding it from 7.23 to 7.25)

Similarly making:

12.44 to 12.45
33.18 to 33.20
52.13 to 52.15

So actually rounding the last two places. Coz obviously customers won't be able to pay 52 dollars 13 cents. So therefore rounding the last cent's (decimal part) making it to 52.15

Thank you.
