Príklady

In the first example we set different parameters to compare the outputs.

<?php
$number = 250000.2557;
// We do not set any optional parameter.
echo number_format($number) . "<br>";
// We can set only the amount of decimal places.
echo number_format($number, 2) . "<br>";
// All the parameters are set.
echo number_format($number, 3, ",", ".") . "<br>";
// The number can also be passed as string.
echo number_format("250000.2557", 1, ",", ".") . "<br>";

In the second example we set the parameters according to the number format used in most countries of the continental Europe.

<?php
echo number_format("1250000.2557", 2, ",", " ") . "<br>";

Formatting of the telephone numbers is really easy due to this function.

<?php
echo number_format("777555123",0 , "", "-") . "<br>";
echo number_format("777555123",0 , "", " ") . "<br>";
