[SOLVED] Number format array?

[lindm]

Is it possible to number format an array?

 

Say I have an array in the format 99999999. I want to add thousand delimiter with a space like this function:

 

number_format($string, 0, ',', ' ');

 

Possible?

I would hope so....

 

 

http://us.php.net/manual/en/function.number-format.php

 

 

It is a function of PHP.

 

// Using format string number_format  ( float $number  , int $decimals  , string $dec_point  , string $thousands_sep  )
$string = 9999999999;
$formattedNumber = number_format($string, 0, '.', ', '); 

 

But I think your parameters are in the wrong spot, try the above.

Wait, how is your array formatted?

[lindm]

Array is formatted without any whitespace.

[DarkWater]

That makes no sense.  Do you know what an array is?  Do you possibly mean you have a string?

[lindm]

Well hope I know what an array is...stored values...

 

What I am looking for is to reformat the whole array in one go.

 

Old approach to change number format for single value:

 

number_format($arrayvalue["xxx"], 0, ',', ' ');

 

Say array is stored in $array.

 

Trying the approach number_format($array, 0, ',', ' '); but no go.

[DarkWater]

Oh, so you have an array with all of the numbers like this?

 

$array[] = 99999999;
$array[] = 28931;
$array[] = 21389183981;

 

Etc.  Correct?

[premiso]

<?php
foreach ($arrayvalue as $key => $val) {
      $arrayvalue[$key] = number_format($val, 0, ',', ' ');
}

print_r($arrayvalue); // print out the array for verification
?>

 

Sorry misunderstood the first part. Hope that helps.

 

You were looking for www.php.net/foreach

If you array is a single dimension and it only contains numbers -- which you want to format then use array_walk

 

eg

 

$numbers = array(1, 12.06593, 1253689, .0669);

echo '<pre>' . print_r($numbers, true) . '</pre>';

array_walk($numbers, 'format_number_array');

echo '<p>FORMATTED:<pre>' . print_r($numbers, true) . '</pre>';

function format_number_array(&$item)
{
    $item = number_format($item, 0, ',', ' ');
}

@wildteen: array_walk() returns a bool indicating success, not the new array.  That's why you pass it in by reference.  array_map() returns the new array, but doesn't take the element by reference.

Yeah had a typo fixed it.

Trying the foreach but stuck:

 

My array is stored in $calc. It is then reformatted as json. This doesn't work:

 

foreach ($calc as $key => $val) {
      $calc[$key] = number_format($val, 0, ',', ' ');
}

echo json_encode($calc);

 

[DarkWater]

The code you just posted should work as expected.  Do:

die(print_r($calc));

Before the json_encode() call.

[premiso]

Read up on json_encode, the post was incorrect, thus removed. Sorry bout that.

[wildteen88]

That code should work fine. This is the test data I used

$calc[] = 99999999;
$calc[] = 28931;
$calc[] = 21389183981;

The output of your script is

["99 999 999","28 931","21 389 183 981"]

Nothing wrong there

[lindm]

Got it! Was an error elsewhere.

 

Thanks all!
