In PHP, you can define a function using the function
keyword, followed by the function name, and the parameters that the function takes (if any). Here is an example of a function that takes two parameters and returns their sum:
1 2 3 |
function sum($num1, $num2) { return $num1 + $num2; } |
In this example, the function name is sum
, and it takes two parameters $num1
and $num2
. The return
keyword is used to return the sum of the two parameters.
You can then call this function by passing in two arguments:
1 2 |
$result = sum(2, 3); echo $result; // Outputs 5 |
In this example, the sum
function is called with the arguments 2
and 3
, and the result is stored in the variable $result
. Finally, the value of $result
is printed to the screen using the echo
statement.
