[RESOLVED] are php functions commonly used?

[Toadums]

Hi, for what I am doing I thought the best way to do it would be to make a recurssive function...but I am not sure if functions works the way that I think they do in php. They are only executed when called right?

I know in java you do like:

 public String test(String j){

return j;
}

What is the protocol do this in php?

make a function that returns a String...The thing that really confused me with php at first was that you dont like say String/int float infront of your variables...so would I just merely put:

 <?php function totest($text){

return $text;

}

thanks!

<?php 

function foo($text)
{

return $text;

} 

echo foo('bar');

//outputs: bar

?>
