quick function help

[tronicsmasta]

hey guys... i have looked around and can't seem to find this answer...

 

How can i return a variable for use from a function? eg:

 

error(60);
echo $err; //I want to use it here... 

function error($err) {

print "Error $err";
return($err);     //i want to use $err after i call the function
}

 

Thanks for the help!

To catch the value returned from a function, you need to do

$err = error(60);

one other quick question.... how can i return an array from a function or multiple variables from a function eg:

From what I read the return function ends the function thus $bar wont be returned.... how can i do this ?!?

 

echo $err;

$multivar = func("blah");

function func($func) {

$foo = "bar";
$bar = $func;

return($foo);
return($bar);

}

[paul2463]

echo $err;

$multivar = func("blah");

function func($func) {

$returnArray[0] = "bar";
$returnArray[1] = $func;

return $returnArray;

}

echo $multivar[0]; //prints out "bar"
echo $multivar[1]; //prints out "blah"
