PHP String Exercises : Format values in currency style

Last update on December 20 2024 10:25:36 (UTC/GMT +8 hours)

Write a PHP script to format values in currency style.

Sample values: value1 = 65.45, value2 = 104.35

Sample Solution:

PHP Code:

<?php
$value1 = 65.45;    // Assigns the value 65.45 to the variable $value1
$value2 = 104.35;   // Assigns the value 104.35 to the variable $value2
// Uses sprintf() function to format the sum of $value1 and $value2 with two decimal places
// %1.2f specifies the format: 1 total width, 2 decimal places
echo sprintf("%1.2f", $value1+$value2)."\n";  // Echoes the formatted sum to the output followed by a newline.
?>

Output:

169.80

Explanation:

In the exercise above,

Two variables, '$value1' and '$value2', are initialized with floating-point numbers 65.45 and 104.35 respectively. These variables represent numerical values.
The "sprintf()" function formats the sum of '$value1' and '$value2'. Inside the "sprintf()" function:

%1.2f is a format specifier where:

%f is a placeholder for a floating-point number.
1.2 specifies the format: 1 total width (including the decimal point and digits before and after it), and 2 decimal places after the decimal point.

$value1 + $value2 calculates the sum of the two values.

The formatted result is then echoed to output, followed by a newline character (\n).
