Relay Function
A relay function, or a relay method, is a function that calls another function, with the same arguments. It is merely relaying the arguments from one to the other.
A relay function also returns the value of the relayed function.
A relay function does not add any added value over the other function, except a renaming of the feature.
Relay functions may be nested several levels, depending on the situation.
<?php
function foo($a) {
return goo($a);
}
function goo($a) {
return hoo($a);
}
function hoo($a) {
return doSomething();
}
?>
