Number format in PHP - php

Question

I want to display price in my front page. But the format of the number required is,
Entered price: 10000 Display: 10,000
Entered price: 10000.10 Display: 10,000.1
Entered price: 10000.01 Display: 10,000.01
if I am using the following code
echo number_format ($price,2,'.',',');
But through this the result is displayed in this manner.
Entered price: 10000 Display: 10,000.00
Please help me to solve this problem

Answer 1

There's a function in PHP called money_format().
Have a look at it on http://php.net/manual/en/function.money-format.php

Answer 2

You have set number of decimial points to 2 so that is why you have 10,000.00. Try to user in this way:
echo number_format ($price,1,'.',',');
And also it is better to use money_format if you are working with money values.

Answer 3

Surely, from a clarity and consistency point of view, having 2 digits after the decimal point makes more sense especially when showing prices.
#barryhunter made a valid point and the following doesn't work.
echo rtrim(number_format($price,2,'.',','),'0.');
However, this does:
trim(trim(number_format($price,2,'.',','),'0'),'.');
Look:
<?php
$a=array('10000.00','10000.10','10000.01');
foreach ($a as $price)
{
echo $price.' - '.rtrim(rtrim(number_format($price,2,'.',','),'0'),'.')."\n";
}
?>
$> php -f t.php
10000.00 - 10,000
10000.10 - 10,000.1
10000.01 - 10,000.01

Answer 4

Personally I would do
echo number_format($price,floor($price)==$price?0:2,'.',',');
displaying a price as 10,000.1 just looks odd to me.
But if you really must
$bits = explode('.',$price);
echo number_format($price,strlen($bits[1]),'.',',');
(edit) In reply to the comment, it works for me...
<?php
$a=array(10000.00,10000.10,10000.01);
foreach ($a as $price)
{
$bits = explode('.',$price);
echo $price.' - '.number_format($price,strlen($bits[1]),'.',',')."\n";
}
?>
$ php t.php
10000 - 10,000
10000.1 - 10,000.1
10000.01 - 10,000.01
