PHP - How Do I Explode A Round?

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.

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()

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

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

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);
}

Hey guys,

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.

All comments and feedback are welcomed.

Hi, I have an array for prices :

forfait="158|Group Session,95|Group half session,45|Private Course,90|zumba course" which is used in a dropdown list where it shows as Group Session (158$) Group half session (95$) etc...

The prices need to be used as an 'amount' field on the gift certificate as the descriptions must show as a 'label' on the gift certificate.

So, I need to ' explode ' both the prices and the descriptions separately.

I can 'explode' de prices using $tmp_forfait=explode("|", $value) and I get 158 95 45 and 90

But, how do I get the descriptions separately, without the prices meaning I need to 'explode' the digits and '|' ...
Anyone can help me with that cope please?
Thank you

Hi all,

I posted a similar question before and got some of the way but still need a little help.

I have a product database with a description column where there are strings broken into lines. I need to find a way to explode() by line break. Currently explode("/n") doesn't work - it only returns one array item. Can anyone help me out?

Thanks!

I store date data in MySql in this format DD-MM-YYYY , and now I need to explode this format when get information from database to get this:
$day = DD , $month = MM , $year = YYYY.

$result =  $db->query("SELECT 
user_birthday  
FROM users 
WHERE user_id = " . mysql_real_escape_string($_SESSION['user_id']) . " 
LIMIT 1");
$row = mysql_fetch_assoc($result);

$birthday = $row['user_birthday'];
and I get this date format: 12-07-1980

How to explode this 3 values in day, month, year?

I have a script that connects to another server to pull data... When it pulls the data it comes back in the following format:

Code: [Select]
t1.sh t2.sh t3.sh test.sh

However using the code bellow does not separate it like it should, it should put one file per line but I think I did something wrong...

Code: [Select]
// Pulls the output from the server:
$var_test = $ssh->exec('./test.sh');
// Explodes it...
$var_test2 = explode(" ", $var_test);
// Echos it one per line...
foreach ($var_test2 as $variable) {
echo '<br>'.$variable;
}

With a database of synonyms, how do I compare a fragment of a texarea sentence split by the php explode function to return only five synonyms out of say 100 synonyms of the same word for each fragment.

The Sql statement is queried to return 5 results
Code: [Select]
<?php
 if (isset($_GET['submit'])) {
$sentence = $_GET['sentence'];
 
// break $sentence using the space character as the delimiter
$words = explode(' ', $sentence);
 
//tell the amount of words using the size of the array
echo 'The sentence has ' . count($words) . ' words.<br />';
 
// loop through and print all the words
for ($i = 0; $i < count($words); $i++)
{
    echo "Piece $i = $words[$i] <br />";

//echo 'Word ' . $i . ' - ' . $words[$i] . '<br />';

//$words=$_GET['words'];
$sel="select * from synonyms where synonym LIKE '%$words[$i]%' limit 3";
$data=mysqli_query($dbc,$sel);
$num= mysqli_num_rows($data);


if (!$data) {
die('<p>Error Retrieving<br/>'.
'Error: ' .mysql_error() . '</p>');}

$datalist=mysqli_fetch_assoc($data);
$synonym=$datalist['synonym'];

?> I intend to use a 2 texareas: 
 1. Code: [Select]
<textarea name="split_sentence"><?php echo "sentence" ?></textarea>   the 1st <texarea> has the original sentence to be split by the explode function.
2. Code: [Select]
<textarea name="split_sentence2"><?php echo ("$words[$i] {{$synonym}}?></textarea> the second <texarea> should take the explode fragments compare it with the query above and return five synonyms per word on a SINGLE <textarea> tag.

3. Besides, I keep getting this offset error on the 2nd <texarea> refering to the $words[Si] array element in the 2nd <textarea>
Below is the full code:
Code: [Select]
`<?php 
//session_start();
  // Define database connection constants
  define('DB_HOST', 'localhost');
  define('DB_USER', 'root');
  define('DB_PASSWORD', '');
  define('DB_NAME', 'moby_thesaurus');

$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

I'm trying to add options to products.

Currently, I have them in this format: Leather reinforced hilt,5.00::Stabbing tip,3.00::Logo,10.00

Code: [Select]
$option_results = mysql_query("SELECT product_options FROM products WHERE product_id='".$product."'");
   while($option_row = mysql_fetch_array($option_results)){
         $option = explode("::", $option_row[0]);
         $option_part = explode(",", $option[0]);
         $option_part[0] = $option_name;
         $option_part[1] = $option_price;
         echo "<li><a href=\"#\">".$option_name.", Add $".$option_price."</a></li>";
    }

I would like the output to be:

<li><a href="#">Leather reinforced hilt, Add $5.00</a></li>
<li><a href="#">Stabbing tip, Add $3.00</a></li>
<li><a href="#">Logo, Add $10.00</a></li>
