How to Remove Leading and Trailing Zeros from Decimals in PHP?

Remove Insignificant Zeros from Decimals in PHP

In PHP, the presence of trailing or leading zeros in decimal values can clutter data representation. To address this, there is a need for an efficient method to remove these unnecessary zeros.

Optimization Technique Using Mathematical Operation

A simple yet optimized approach is to apply the following mathematical operation:

$num 0

where $num represents the decimal value with trailing zeros. This technique effectively eliminates any trailing zeros, as demonstrated in the examples below:

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

Simplified Approach Using Type Casting

Alternatively, you can cast the decimal value to a float using either:

float($num)

or

floatval($num)

While both methods achieve the same result, the mathematical operation $num 0 is often preferred due to its simplicity and performance.

Examples with Leading Zeros

This technique also handles leading zeros:

echo '000.012' + 0; // Output: 0.012

In conclusion, using $num 0 provides a fast and efficient way to remove insignificant zero digits from decimal values in PHP, ensuring a clean and optimized representation of data.
