PHP program to find the power of any number x^y
ADVERTISEMENTS
PHP program to find the power of any number x^y. There are you will learn how to find the power of any number x^y in PHP language.
Formula:
r = b ^ y
where:
r = result
b = base value
y = exponent value
There are two ways to implement these formulae:
- By using the default method
- Second, by using the pow() function
1. By using the default method
<?php
// PHP program to find the power of any number
$b = 5;
$e = 7;
$r = 1;
$i = 1;
// b = base
// e = exponent
// r = result
// finding power of base value by equiping exponent value
while($i <= $e) {
$r *= $b;
$i++;
}
// Output
echo "Result:: " . $b . "^" . $e . " = " . $r;
?>
Output:
Result:: 5^7 = 78125
2. By using pow() function
<?php
// PHP program to find the power of any number by using pow() function
$b = 5;
$e = 7;
$r = 1;
// b = base
// e = exponent
// r = result
// finding power of base value by equiping exponent value
$r = pow($b, $e);
// Output
echo "Result:: " . $b . "^" . $e . " = " . $r;
?>
Output:
Result:: 5^7 = 78125
