$var = number_format(2234,2);

$var = number_format($var,2);

echo $var;

# Expected Output: 2,234.00

# Actual Output: 2.00

To fix, remove the thousands separator by setting the decimal point and thousands separator parameters like so:

$var = number_format(2234,2,‘.‘,‘‘);

$var = number_format($var,2,‘.‘,‘‘);

echo $var;

# Expected Output: 2234.00

# Actual Output: 2234.00

?>

If it‘s 3 digits or less, then it works normally with only the decimals parameter since there is no thousands separator.

$var = number_format(123,2);

$var = number_format($var,2);

echo $var;

# Expected Output: 123.00

# Actual Output: 123.00
