How to Efficiently Remove Leading and Trailing Zeros from Decimal Numbers in PHP?

Eliminating Redundant Zeros from Decimal Numbers in PHP

Question:

How can I efficiently remove trailing and leading zeroes from decimal numbers in PHP? I need a method that handles values such as:

• 125.00 -> 125
• 966.70 -> 966.7
• 844.011 -> 844.011

Answer:

PHP offers a simple solution using the ' ' operator:

<code class="php">echo 125.00 + 0; // 125
echo '125.00' + 0; // 125
echo 966.70 + 0; // 966.7</code>

Explanation:

Internally, this operation coerces the number to a float using either (float)$num or floatval($num). However, this approach is less cryptic and provides an optimized way to remove useless zero digits from decimals in PHP.
