What Is the Js Equivalent to the PHP Function Number_Format

What is the JS equivalent to the PHP function number_format?

is this what you'd like to get?

yourFloatVarHere.toFixed(2);

voilà.

number_format function of php and calculate with js

Show the formatted number but echo the unformatted number elsewhere and use that in js. For example:

PHP

<div id="number" data-myvalue="<?=$number?>"><?=number_format($number)?></div>

JAVASCRIPT

var myvalue = $("#number").data("myvalue");

What is the exact equivalent of JS: something.toFixed() in PHP?

I found that sprintf and number_format both round the number, so i used this:

$number = 2.4232;
$decimals = 3;
$expo = pow(10,$decimals);
$number = intval($number*$expo)/$expo; //  = 2423/100

Number Format in Javascript + conversion?

Use toFixed() method of float:

var ttc_txt = parseFloat(ttc_val).toFixed(2);

Returns something like "123.00"
You can use it as string. If you need a strict type string, just add +"" to expression:

var ttc_txt = parseFloat(ttc_val).toFixed(2)+"";

Is there a PHP function equivalent to JavaScript function toLocaleString()

PHP does allow for Number Formatting, but does not have a function that can do exactly as Javascript's toLocaleString().

PHP's NumberFormatter can be used to format decimals. The JavaScript implementation sets the locale value on the client side of the browser and then outputs the results.

PHP has a similar method for setting the locale value, but is performed on the server. This could result in unintended consequences.

"Warning: The locale information is maintained per process, not per thread. If you are running PHP on a multithreaded server API like IIS, HHVM or Apache on Windows, you may experience sudden changes in locale settings while a script is running, though the script itself never called setlocale(). This happens due to other scripts running in different threads of the same process at the same time, changing the process-wide locale using setlocale()."

NumberFormatter in PHP vs NumberFormat in JS

I tried this approach:

<?php

function process($locale, $value, $currency){
    $fmt = numfmt_create($locale, NumberFormatter::CURRENCY );
    echo "Locale: $locale, Currency: $currency, Result: " . $fmt->formatCurrency($value, $currency) . "\n";
}

$locales = ["tl_PH","fil_PH", "en_US"];
$currencies = ["USD", "PHP"];
$value = 5125.99;

foreach ($locales as $locale){
    foreach ($currencies as $currency){
        process($locale, $value, $currency);
    }
}

and got consistent results:

Locale: tl_PH, Currency: USD, Result: $5,125.99
Locale: tl_PH, Currency: PHP, Result: ₱5,125.99
Locale: fil_PH, Currency: USD, Result: $5,125.99
Locale: fil_PH, Currency: PHP, Result: ₱5,125.99
Locale: en_US, Currency: USD, Result: $5,125.99
Locale: en_US, Currency: PHP, Result: PHP 5,125.99

Thus, to be 100% safe, I would suggest creating a small server side component for the formatting purposes, so that you can pass the locale, value and currency and always have the same result regardless if it's backend or frontend that needs the formatted string.

Also, note that tl-PH and tl_PH is not the same. Use tl_PH and fil_PH and en_US consistently.

Parameter passing from JavaScript to PHP

Instead of formatting your data in the view file, format your data in controller and then send it to view. So you can use the formatted data directly.

Change your controller code to following:
public function addStock(Request $request) {

    $data = new ShoppingCartDetail();
    $data->cart_id = $request->input('cart_id');
    $data->stock_id = $request->input('stock_id');
    $data->price = 1;
    $data->save();
    $data->x = 4;
    $data->price = 1200;

    $formattedPrice = number_format($data->x * $data->price, '2' , ',', '.');

  return response()->json(["data" => $data, 'formattedPrice' => $formattedPrice]);
}

You can then use the new "formattedPrice":

$('#5').replaceWith("<span class='para fw6'>" + data.formattedPrice + "TL</span>");

Replicate number_format

Here's a working version of Kae Verens' function.

function number_format($num){
  $num=(string)$num;
  $len=strlen($num);
  $newnum='';
  for ($i=0; $i<$len; ++$i) {
    if (($i%3==0) && $i) {
      $newnum=','.$newnum;
    }
    $newnum=$num[$len-$i-1].$newnum;
  }
  return $newnum;
}
