What are some common misconceptions about number_format in PHP and how can they be clarified?

One common misconception about number_format in PHP is that it always rounds numbers to the nearest whole number. However, the function allows for specifying the number of decimal places to include. To clarify this, simply include the desired number of decimal places as the second parameter in the number_format function.

$value = 1234.56789;
$formatted_value = number_format($value, 2); // Outputs: 1,234.57
echo $formatted_value;
