Show Me the Money! 💰💰💰

Oh, hey there, tech-savvy folks! Have you ever been faced with the challenge of showing a number in PHP to just two decimal places? 🤔 Fear not, my friends, for I bring tidings of easy solutions that will make your coding life a breeze! 🌬️💨

The PHP Rounding Dilemma 😕

So, you've got this shiny PHP string from your trusty database, and you want to format it in a way that looks all cool and professional-like, with exactly two decimal places. 💁‍♀️💁‍♂️ However, the question is: how do you do it? 🤷‍♀️

Solution Unleashed 💡

To tackle this conundrum, we'll need to define a magical round_to_2dp() function that will effortlessly turn our mundane numbers into stylish ones. Here's the code snippet you've all been waiting for: 🎉📝

function round_to_2dp($number) {
    return number_format((float)$number, 2, '.', '');
}

Deconstructing the Sorcery 🧙‍♀️✨

Let's break down this dazzling code and understand the sorcery behind it, shall we? 😏

• We start by declaring our round_to_2dp() function, which takes in a parameter named $number.

• Inside the function, we utilize the number_format() function, which is PHP's secret weapon for number formatting.

• We cast the $number string to a float using (float)$number because number_format() expects a numeric input.

• The number_format() function then formats our float to have two decimal places, using a period as the decimal separator. We pass in the parameters 2 and '.' to achieve this effect.

• Finally, we proudly return the beautifully formatted number to the caller.

Test Drive the Magic 🚗💨

Let's put our sorcery to the test, shall we? Simply copy the following code snippet into your PHP file, and prepare to be awed by the results: 🧙‍♂️🔮

$number = "520"; // It's a string from a database

$formatted_number = round_to_2dp($number);

echo $formatted_number;

Behold, the moment of truth! When you run this code, you should see the majestic result of 520.00 gracing your screen. 🌟🌟🌟
