How to Display Values in One Decimal Place with PHP

You can use the number_format() function in PHP to display values in one decimal place. The number_format() function formats a number with grouped thousands and a specified number of decimal points.

Here’s an example:

$value = 12.3456;
$formatted_value = number_format($value, 1);
echo $formatted_value;

Output:

12.3

In this example, the number_format() function takes two arguments: the first argument is the value you want to format (in this case, $value), and the second argument is the number of decimal points you want to display (in this case, 1).

You can also specify a decimal separator and a thousands separator in the number_format() function. For example:

$value = 12345.6789;
$formatted_value = number_format($value, 1, '.', ',');
echo $formatted_value;

Output:

12,345.7

In this example, the third argument (“.”) specifies the decimal separator, and the fourth argument (“,”) specifies the thousands separator.
