PHP Return Value From Function
When PHP encounters a return statement inside a function, it halts the processing of the function and “returns” control to the main body of the program. Let’s see the example of return value from function in PHP
Ex:
<?php
function cube($n){
return $n*$n*$n;
}
echo "Cube of 3 is : " . cube(3);
?>
Output:
Cube of 3 is: 27
Factorial program return value
<?php
function factorial($x)
{
for($f=1, $i=1; $i<=$x; $i++)
$f *= $i;
return ($f);
}
echo "</br> Factorial of 5 = " . factorial(5);
echo "</br> Factorial of 7 = " . factorial(7);
?>
Output:
