Remove useless zero digits from decimals in PHP

✔ Recommended Answer

$num + 0 does the trick.

echo 125.00 + 0; // 125echo '125.00' + 0; // 125echo 966.70 + 0; // 966.7

Internally, this is equivalent to casting to float with (float)$num or floatval($num) but I find it simpler.

Method #2

To remove useless zero digits from decimals in PHP, you can use the rtrim() and number_format() functions together. Here's an example:

php
$number = 12.3400;

// Use number_format() to format the number with 2 decimal places
$formatted = number_format($number, 2);

// Use rtrim() to remove any trailing zeros
$formatted = rtrim($formatted, '0');

// If the last character is a decimal point, remove it as well
$formatted = rtrim($formatted, '.');

echo $formatted; // Outputs "12.34"

In this example, the number_format() function is used to format the number with 2 decimal places. The resulting string includes trailing zeros, so the rtrim() function is used to remove them. If the last character in the resulting string is a decimal point, it is also removed.

Note that this approach assumes that you always want to display the number with 2 decimal places. If you want to display a variable number of decimal places, you can use the round() function with a precision argument to round the number to the desired number of decimal places before formatting it with number_format().
