What are some common methods for manipulating integers in PHP?
One common method for manipulating integers in PHP is by using arithmetic operators such as addition, subtraction, multiplication, and division. Another method is to use built-in functions like `abs()` for finding the absolute value of an integer, `pow()` for calculating the power of a number, and `round()` for rounding a number to a specified precision.
// Example of manipulating integers in PHP
$number1 = 10;
$number2 = 5;
// Addition
$sum = $number1 + $number2;
echo "Sum: " . $sum . "<br>";
// Subtraction
$diff = $number1 - $number2;
echo "Difference: " . $diff . "<br>";
// Multiplication
$product = $number1 * $number2;
echo "Product: " . $product . "<br>";
// Division
$quotient = $number1 / $number2;
echo "Quotient: " . $quotient . "<br>";
// Absolute value
$negativeNumber = -15;
$absoluteValue = abs($negativeNumber);
echo "Absolute Value: " . $absoluteValue . "<br>";
// Power
$base = 2;
$exponent = 3;
$power = pow($base, $exponent);
echo "Power: " . $power . "<br>";
// Rounding
$number = 3.14159;
$roundedNumber = round($number, 2);
echo "Rounded Number: " . $roundedNumber . "<br>";
