PHP - Round To Nearest 0 Or 5

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

?>

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

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 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()

HOw to get the AVERAGE of my entire database?

$query = "SELECT ROUND(AVG(scores)) FROM table";

Thanks!

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?

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">';

echo ''.$i.'. <td class="lista">'.$filnamn.'<td class="lista">'.$filtyp.' <td class="lista">'.$filstorlek.' <td class="lista"><a href="download.php?id='.$id.'"'.$a.'"><img src="download-icon.jpg" class="imagedow"></a>';




}

echo "</table>";

?>

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

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,

I use the code below to add a corners to an image and it works great but when i add a border to the image it add a square.... any ideas how i can add a border to the rounded image?

<?php
$image_file = $_GET['src'];
$corner_radius = isset($_GET['radius']) ? $_GET['radius'] : 20; // The default corner radius is set to 20px
$topleft = (isset($_GET['topleft']) and $_GET['topleft'] == "no") ? false : true; // Top-left rounded corner is shown by default
$bottomleft = (isset($_GET['bottomleft']) and $_GET['bottomleft'] == "no") ? false : true; // Bottom-left rounded corner is shown by default
$bottomright = (isset($_GET['bottomright']) and $_GET['bottomright'] == "no") ? false : true; // Bottom-right rounded corner is shown by default
$topright = (isset($_GET['topright']) and $_GET['topright'] == "no") ? false : true; // Top-right rounded corner is shown by default
$imagetype=strtolower($_GET['imagetype']);
$backcolor=$_GET['backcolor'];
$endsize=$corner_radius;
$startsize=$endsize*3-1;
$arcsize=$startsize*2+1;

if (($imagetype=='jpeg') or ($imagetype=='jpg')) {
$image = imagecreatefromjpeg($image_file);
} else {

$image = imagecreatefromgif($image_file);

}
}


$size = getimagesize($image_file);
// Top-left corner
$background = imagecreatetruecolor($size[0],$size[1]);
imagecopymerge($background, $image, 0, 0, 0, 0, $size[0], $size[1], 100);
$startx=$size[0]*2-1;
$starty=$size[1]*2-1;
$im_temp = imagecreatetruecolor($startx,$starty);
imagecopyresampled($im_temp, $background, 0, 0, 0, 0, $startx, $starty, $size[0], $size[1]);

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.
