    float $num,
    int $decimals = 0,
    ?string $decimal_separator = ".",
    ?string $thousands_separator = ","
): string

Examples

Example #1 number_format() Example

For instance, French notation usually use two decimals, comma (',') as decimal separator, and space (' ') as thousand separator. The following example demonstrates various ways to format a number:

$number

It's not explicitly documented; number_format also rounds:

$numbers = array(0.001, 0.002, 0.003, 0.004, 0.005, 0.006, 0.007, 0.008, 0.009);
foreach ($numbers as $number)
    print $number."->".number_format($number, 2, '.', ',')."
";
?>

0.001->0.00
0.002->0.00
0.003->0.00
0.004->0.00
0.005->0.01
0.006->0.01
0.007->0.01
0.008->0.01
0.009->0.01

Note: use NumberFormatter to convert in human-readable format instead  user function from comments:
echo NumberFormatter::create('en', NumberFormatter::SPELLOUT)->format(12309); // twelve thousand three hundred nine
echo NumberFormatter::create('ru', NumberFormatter::SPELLOUT)->format(12307.5); //  двенадцать тысяч триста семь целых пять десятых

For Zero fill - just use the sprintf() function

$pr_id = 1;
$pr_id = sprintf("%03d", $pr_id);
echo $pr_id;

//outputs 001
-----------------

$pr_id = 10;
$pr_id = sprintf("%03d", $pr_id);
echo $pr_id;

//outputs 010
-----------------

You can change %03d to %04d, etc.

I ran across an issue where I wanted to keep the entered precision of a real value, without arbitrarily rounding off what the user had submitted.

I figured it out with a quick explode on the number before formatting. I could then format either side of the decimal.

      function number_format_unlimited_precision($number,$decimal = '.')
      {
           $broken_number = explode($decimal,$number);
           return number_format($broken_number[0]).$decimal.$broken_number[1];
      }
?>

Be carreful, when you're using French notation
means : number_format(124.25, 2 , ',' , ' ') with ',' as dec_point,

Don't forget to specify thousands_sep that default is ',' to another value, otherwise function will return null.

Simple function to show money as only dollars if no cents, but will show 2 decimals if cents exist.

The 'cents' flag can force to never or always show 2 decimals

// formats money to a whole number or with 2 decimals; includes a dollar sign in front
function formatMoney($number, $cents = 1) { // cents: 0=never, 1=if needed, 2=always
  if (is_numeric($number)) { // a number
    if (!$number) { // zero
      $money = ($cents == 2 ? '0.00' : '0'); // output zero
    } else { // value
      if (floor($number) == $number) { // whole number
        $money = number_format($number, ($cents == 2 ? 2 : 0)); // format
      } else { // cents
        $money = number_format(round($number, 2), ($cents == 0 ? 0 : 2)); // format
      } // integer or decimal
    } // value
    return '$'.$money;
  } // numeric
} // formatMoney$a = array(1, 1234, 1.5, 1.234, 2.345, 2.001, 2.100, '1.000', '1.2345', '12345', 0, '0.00');// show cents if needed ($cents=1)

Just an observation:
The number_format rounds the value of the variable.

$val1 = 1.233;
$val2 = 1.235;
$val3 = 1.237;

echo number_format($val1,2,",","."); // returns: 1,23
echo number_format($val2,2,",","."); // returns: 1,24
echo number_format($val3,2,",","."); // returns: 1,24

When apply number_format on number with separator on thousands, result is wrong. This function accept number of any format
function format_price($number,$decPlaces,$decSep,$thouSep){//$number - number for format
    //$decPlaces - number of decimal places
    //$decSep - separator for decimals
    //$thouSep - separator for thousands

        //first remove all white spaces

if you want   as a separator and use windows charset this piece of code may help:

$number=number_format($number,2,'.',chr(0xA0));

formatting numbers may be more easy if u use number_format function.

I also wrote this :
function something($number)
{
    $locale = localeconv();
    return number_format($number,
       $locale['frac_digits'],
        $locale['decimal_point'],
        $locale['thousands_sep']);
}

hope this helps =)

You can use:

    number_format( $number, '.', ' ' )

Rationale:

Since 2003, the Internationa Standard of Units regulated that groups of three are to be separated by spaces and not dots or commas:

We can read about the S.I. in wikipedia about the numbers:

"Spaces should be used as a thousands separator (1000000) in contrast to commas or periods (1,000,000 or 1.000.000) to reduce confusion resulting from the variation between these forms in different countries."

here https://en.wikipedia.org/wiki/International_System_of_Units in the section "General Rules".

More specifically in an official document they introduce the concept of "thin space":

"for numbers with many digits the digits may be divided into groups of three by a thin space, in order to facilitate reading. Neither dots nor commas are inserted in the spaces between groups of three."

here https://mcyt.educa.madrid.org/laboratorios/Documentos/Otros/documentos/si_brochure_8_en.pdf in page 41, in the section "5.3.4 Formatting numbers, and the decimal marker".

Finally, also in wikipedia, we can read about the separation of digits:

"It is also used in the International System of Units and in many countries as a thousands separator when writing numbers in groups of three digits, in order to facilitate reading."

here: https://en.wikipedia.org/wiki/Thin_space

Note that "THIN SPACE" is breakable and for a non-breakable space we also have the "NARROW NO-BREAK SPACE". Nevertheless the definition is a bit different:

"Also starting from release 34 of Unicode Common Locale Data Repository (CLDR) the NNBSP is used in numbers as thousands group separator for French and Spanish locale."

We can read it here: https://en.wikipedia.org/wiki/Non-breaking_space at the end of the article

So, conclusion: We can use   for the regular one or   for the non-breaking one in the number_format function to accomodate modern times and forget once and for all to use dots or commas for the thousands.

simpler function to convert a number in bytes, kilobytes....

function bytes($a) {
    $unim = array("B","KB","MB","GB","TB","PB");
    $c = 0;
    while ($a>=1024) {
        $c++;
        $a = $a/1024;
    }
    return number_format($a,($c ? 2 : 0),",",".")." ".$unim[$c];
}?>

you may also add others units over PeraBytes when the hard disks will reach 1024 PB :)

Note: Changing the number format loses PHP's ability to count. So do not change number format if you wish to do anything besides showing the number.

In my function my_number_format() [shown below] there was a bug.

If a negative number which is smaller than 1 was entered (-0,...), then the result was wrongly positive because +0 is equal to -0 (the content of $tmp[0] which was interpretet as numeric value).

Here is the corrected version:

function my_number_format($number, $dec_point, $thousands_sep)
{
    $was_neg = $number < 0; // Because +0 == -0
    $number = abs($number); $tmp = explode('.', $number);

If you want a number of digits after the point, but not unnecessary zeros.
Eg.
number_format(1.20000,4) = 1.2000
num_format(1.20000,4,0) = 1.2

number_format(1.20000,4) = 1.2000
num_format(1.20000,4,2) = 1.20

number_format(1.23456,4) = 1.2345
num_format(1.23456,4,2) = 1.2345

function num_format($numVal,$afterPoint=2,$minAfterPoint=0,$thousandSep=",",$decPoint="."){
  // Same as number_format() but without unnecessary zeros.
  $ret = number_format($numVal,$afterPoint,$decPoint,$thousandSep);
  if($afterPoint!=$minAfterPoint){
    while(($afterPoint>$minAfterPoint) && (substr($ret,-1) =="0") ){
      // $minAfterPoint!=$minAfterPoint and number ends with a '0'
      // Remove '0' from end of string and set $afterPoint=$afterPoint-1
      $ret = substr($ret,0,-1);
      $afterPoint = $afterPoint-1;

Please be careful with stm555 at hotmail dot com's solution.
If you pass some little negative number (-1 < $number < 0) such as -0.01, the integer part would be converted to 0, so that the sign is eventually lost.
Here is a fixed version:

      function number_format_unlimited_precision($number,$decimal = '.')
      {
           $broken_number = explode('.', abs($number));
           $sign = $number < 0 ? '-' : '';
           return $sign.number_format($broken_number[0]).$decimal.$broken_number[1];
      }

If you use space as a separator, it will break on that space in HTML tables...

Furthermore, number_format doesn't like ' ' as a fourth parameter. I wrote the following function to display the numbers in an HTML table.

  function numberfix($number)
  {
    $number = number_format($number,0,","," ");
    return str_replace(" ", " ", $number);
  }

I'd like to comment to the old notes of "stm555" and "woodynadobhar".
They wrote about "number_format_unlimited_precision()".
I guess many of us need that kind of function, which is the almost same function as number_format but don't round a number.

Does Anyone know any new solution in a recent PHP version?

...
If no, how about the following function? (I fixed somethings like bugs of the function in the old comment.)
function number_format_unchanged_precision($number, $dec_point='.', $thousands_sep=','){
    if($dec_point==$thousands_sep){
        trigger_error('2 parameters for ' . __METHOD__ . '() have the same value, that is "' . $dec_point . '" for $dec_point and $thousands_sep', E_USER_WARNING);
        // It corresponds "PHP Warning:  Wrong parameter count for number_format()", which occurs when you use $dec_point without $thousands_sep to number_format().
    }
    if(preg_match('{\.\d+}', $number, $matches)===1){
        $decimals = strlen($matches[0]) - 1;
    }else{
        $decimals = 0;
    }
    return number_format($number, $decimals, $dec_point, $thousands_sep);
}
var_dump(number_format_unchanged_precision(1234.5678, ',', '.'));
var_dump(number_format_unchanged_precision(1234.5678, ','));
var_dump(number_format_unchanged_precision(12345678));
var_dump(number_format_unchanged_precision(-0.5678, ',', '.'));  // It occurred a bug with the function in the old comment.

I'm not sure if this is the right place anyway, but "ben at last dot fm"'s ordinal function can be simplified further by removing the redundant "floor" (the result of floor is still a float, it's the "%" that's converting to int) and outer switch.

Note that this version also returns the number with the suffix on the end, not just the suffix.

function ordinal($num)
{
    // Special case "teenth"
    if ( ($num / 10) % 10 != 1 )
    {
        // Handle 1st, 2nd, 3rd
        switch( $num % 10 )
        {
            case 1: return $num . 'st';
            case 2: return $num . 'nd';
            case 3: return $num . 'rd'; 
        }
    }
    // Everything else is "nth"
    return $num . 'th';
}
?>

I was looking for a SIMPLE way to format currency and account for negative values while not losing the calculation properties of my number.  Here's my function - it's not rocket science, but maybe can help someone along the way.

function wims_currency($number) {
   if ($number < 0) {
     $print_number = "($ " . str_replace('-', '', number_format ($number, 2, ".", ",")) . ")";
    } else {
     $print_number = "$ " .  number_format ($number, 2, ".", ",") ;
   }
   return $print_number;
}
?>
Sample use:

$pur_po_total =  ($pur_po_total + $pur_item_total);
$print_pur_po_total = wims_currency($pur_po_total);
?>

Returns (for example)    $ 44,561.00 or, if a negative ($ 407,250.00)

This way, I use my 1st variable for calculations and my 2nd variable for output.  I'm sure there are better ways to do it,  but this got me back on track.

Using the number_format I'm having some unexpected results.  30% of 14.95 (14.95 * .3) = 4.485.  Now 4.485 rounded to two decimal places should give me 4.49.

Example:
echo number_format(14.95 * .3, 2, '.', '') . "\n";
echo number_format(4.485, 2, '.', '') . "\n";
?>

Unexpected Results:
4.48
4.49

A simple funtion to format american dollars.

function formatMoney($money) {
    if($money<1) {
        $money='¢'.$money*100;
    }
    else {
        $dollars=intval($money);
        $cents=$money-$dollars;
        $cents=$cents*100;
        $money='$'.$dollars.' and ¢'.$cents;
    }
    return $money;
}
echo formatmoney('52.342');
?>
This will output: "   $52 and ¢34.2  ".

This is a simple and useful function to convert a byte number in a KB  or MB:

function filesize_format ($bytes) {
  $bytes=(float)$bytes;
  if ($bytes<1024){
  $numero=number_format($bytes, 0, ',', '.')." Byte";
  return $numero;
  }
  if ($bytes<1048576){
      $numero=number_format($bytes/1024, 2, ',', '.')." KByte";
  return $numero;
  }
  if ($bytes>=1048576){
      $numero=number_format($bytes/1048576, 2, ',', '.')." MByte";
  return $numero;
  }
}
?>

If you want to display a number ending with ,- (like 200,-) when there are no decimal characters and display the decimals when there are decimal characters i use:

function DisplayDouble($value)
  {
  list($whole, $decimals) = split ('[.,]', $value, 2);
  if (intval($decimals) > 0)
    return number_format($value,2,".",",");
  else
    return number_format($value,0,".",",") .",-";
  }

See also the documentation for localeconv, which will provide values for decimal point and thousands separator from the C standard library.

Of course localeconv features many more locale information, like indicating to put the negative sign behind the value for some locale settings which can't be used to customize present number_format.

What do you do if some of your numbers have decimal places, and some don't?  You can switch between functions, but if you're building it in a loop, that's not a good solution.  Instead, we have the same as below, with a slight change:

function number_format_unlimited_precision($number,$decimal = '.'){
    $broken_number = explode($decimal,$number);
    if($broken_number[1]==0){
        return number_format($broken_number[0]);
    }else{
        return number_format($broken_number[0]).$decimal.$broken_number[1];
    };
};
