How to append zero after 4.5 to make it 4.50 in PHP?

Question

I know it may be a silly one and it may be duplicate question as well, but I can't find any proper question posted before(may be its my incapability)

I have a value fetched from DB... its say like

4.5   which should be 4.500
0.01  which should be 0.010
11    which should be 11.000

How can I achieve this in PHP?

Answer 1

Simply format it with sprinft to make it a floating point number to 2 decimal places.

echo sprintf("%.2f", 4.5);

If you change the 2 to a 3 you will get your format you've listed.

echo sprintf("%.3f", 4.5) . PHP_EOL;
echo sprintf("%.3f", 0.01) . PHP_EOL;
echo sprintf("%.3f", 11) . PHP_EOL;

Answer 2

php.net/number_format

number_format(4.5,2);

Answer 3

Use the function number_format

Trailing zeros to the right of a decimal point is not supported in PHP. You need to format the number to string.

$value = number_format($value,3);

Answer 4

Modern way is to use NumberFormatter which formats numbers according to set locale.

$fmt = new NumberFormatter('en-US', NumberFormatter::DECIMAL);
$fmt->setAttribute(NumberFormatter::MAX_FRACTION_DIGITS, 3);
$fmt->format(1234567.891234567890000);

Answer 5

If You use mysql then Use FORMAT function like SELECT FORMAT(4.5,4)
