Removing Trailing Zeros from Decimal Numbers in PHP

In PHP, removing trailing zero digits from decimals can be a common task. Consider the following scenario: you have a set of numbers like 125.00, 966.70, and 844.011 that you want to display without the unnecessary zero digits.

Fast and Optimized Solution

To accomplish this efficiently, you can employ the simple yet effective solution of adding the number to 0. This technique, represented by $num 0, casts the number to a float and removes any trailing zeros.

echo 125.00   0; // Output: 125
echo '125.00'   0; // Output: 125
echo 966.70   0; // Output: 966.7

Equivalent Castings

Internally, this method is equivalent to casting the number to a float using (float)$num or floatval($num). However, adding to 0 provides a more straightforward and concise approach.

By leveraging this optimized solution, you can quickly remove trailing zero digits from decimals in PHP without compromising efficiency.
