[RESOLVED] Return var from function

[benracer]

Could anyone point me in the right direction as to returning the variable 'error' from a function....

Function - Check

function check($v1,$v2){
	if($v1 == $v2){
	  // True
	}else{
	  // False so run error_return function
		error_return("Sorry, v1 and v2 do not match.");
	}
}

Function - Ouput error

function error_return($var){
global $error;
	$error =  "<div class='error'>".$var."</div>";
	return $error;
}

Where I would like to echo $error.

check("1","1");
echo $error;

Many thanks,
Ben

Solved - Needed to define $error as a global var.

Using the 'global' keyword is a deprecated coding practice. In this case, I would say it'd be much better to [man]throw[/man] an exception instead.
