PHP - Trouble With Number_format

Trying to get my output to to show 2 decimal places but keep getting syntax errors please help.
Here's the code i have.

Code: [Select]
<?php
// Input Data From Form
$Cost = $_POST['fielda'];
//$Cost2 = number_format(,2);
//Set Current Date & Shipping Date (15 days)
$Date = date('l, F d, Y');
$ShipDate = date('F d, Y',strtotime('+ 15 days'));

$Tax = ($Cost * .06);
$Ship = 0;
//$Sub = ($Cost + $Tax);

//Calculate Shipping
if ($Cost <= 25.99 ){
   $Ship = 3.00; }
if ($Cost >= 26.00 && $Cost <= 50.99 ){
   $Ship = 4.00;}
if ($Cost >= 51.00 && $Cost <= 75.00) {
   $Ship = 5.00;}
if ($Cost > 75.00) {
   $Ship = 6.00;}
   
   //Calculate Order Total
$Total = ($Cost + $Tax + $Ship);

print " Date: $Date<br><br>";
print " Cost : $$Cost<br><br> Tax: $$Tax<br><br> Shipping: $$Ship<br><br> Total: $$Total<br><br>";
print "Estimated Ship Date is $ShipDate<br> " ;

?>

MOD EDIT: code tags added.

Hello
I'm getting the following error:
number_format() expects parameter 1 to be double, string given in file path on line 118

And this is what's on line 118:
Code: [Select]
$_SESSION['dataValue3'] = number_format($dataValue[3]);
Any help would be greatly appreciated.

I am looking into sotring values in the sql database as "29824478.15" for example,

now i use the number_format function to display as: 29,824,478

is it possible to get it to display as: 29.8m if its a million number and 0.29m if its less than a million for example?

Hi..

I used this code for displaying formatted number and I notice that instead comma(,) it become point(.):

Code: [Select]
$P28_maxdoz = $row['P28_maxdoz']; 
$P28_maxdoz = number_format($P28_maxdoz, 2, '.', ',');


<table>
<tr>
<td><input type='text' name='P28_maxdoz' value="<?php echo $P28_maxdoz;?>"></td>
</tr>
</table>

the output is : 22.782.20

i need output is : 22,782.20

Thank you

Building a website for work. I am struggling with the login for some reason. I`m using a lot of the same code as I did for my personal site and a few other websites I`ve programmed which has always worked. But for some reason, it isn`t working now. I`ve already told it to display to me the information that`s being processed and that is all correct (it even updates the database like it`s supposed to). It just won`t show the person being logged in, which defeats the purpose of logging in, yanno?

Here are all the files in question.

login.php

Can anyone see why it works on everything but getting the person logged in?
