[SOLVED] Why doesnt this function return the result?

[JJohnsenDK]

Hey

 

Why doesnt this function return the result in $returnstr? I can echo the result inside the if statement, as you can see in the code. So where is the error?

 

<?php
function f($str){
$returnstr = "Resultat: ";
if(findLastCharInString($str) == "("){
	$returnstr .= substr($str, 0, -1);
	echo $returnstr."<br>";
}else{
	echo $str."<br>";
	f(substr($str, 0, -1));
}

return $returnstr."222";

}

$test = f("Mohair sokker sort (Large)");

echo "test: ".$test;
?>

it calls f() on the inside, and returns it to the else{} statement... but you don't do anything with it so it's lost. Try changing

f(substr($str, 0, -1));

 

to

 

$returnstr = f(substr($str, 0, -1));

 

that MIGHT return what you expect, it might return something else (I don't know what you want).... at least it will give you some idea of how to refine your function (which, frankly, could probably be done more efficiently and safer);

Works! thanks genericnumber1!
