What are common mathematical functions in PHP and how can they be used?

In PHP, some common mathematical functions include sqrt() for calculating the square root of a number, pow() for raising a number to a power, round() for rounding a number to the nearest integer, and rand() for generating a random number within a specified range. These functions can be used to perform various mathematical operations in PHP programming. 

// Example of using mathematical functions in PHP
$number = 16;

// Calculate the square root of a number
$squareRoot = sqrt($number);
echo "Square root of $number is: $squareRoot <br>";

// Raise a number to a power
$power = pow($number, 2);
echo "$number raised to the power of 2 is: $power <br>";

// Round a number to the nearest integer
$roundedNumber = round(5.6);
echo "Rounded number: $roundedNumber <br>";

// Generate a random number within a range
$randomNumber = rand(1, 10);
echo "Random number between 1 and 10: $randomNumber <br>";
