You could use this in Functions:
<?php
function function_name($number){
$result = $number*2;
return $result;
}
//Direct:
echo function_name(3);
//Or with a variable:
$var = function_name(4);
echo $var;
?>
This will return and show on the screen number 6 and 8.
Using return is much better, because you get the function as a variable, and you can easily use
string functions.
The way without return:
<?php
function function_name($number){
$result = $number*2;
echo $result;
}
function_name(3);
?>
