Return in a function - PHP -

even if understand doing,i can't seem find logic in return $totaal does. below working code:

<?php function adding ($getal1, $getal2){ $totaal = $getal1 + $getal2; homecoming $totaal; } function substract ($getal1, $getal2){ $totaal = $getal1 - $getal2; homecoming $totaal; } $getal1=10; $getal2=2; echo adding ($getal1, $getal2) . "<br>"; echo substract ($getal1, $getal2); ?>

i create function , phone call later echo'ing return $totaal in function. never phone call it, without homecoming blanks.

i must missing kind of logic in brains....

return word says returns (gives back) something. in case either $var1 + $var2 or $var1 - $var2.

variables within of function can't accessed outside of it. return can within function utilize oustide of it.

keep in mind, return end execution of function.
