Using variables outside the loop

[livewirerules]

How do i use the values withing a while loop out side the loop?

 

eg:

$sql="select *from custwhere account='".$number."'";
	$result=mysql_query($sql) or die(mysql_error());

	while ($row=mysql_fetch_array($result)) {
		$name=$row['username'];
$email=$row['email'];

	}

 

I want to use the variables $name and $email outside the loop.. Ho wdo i do it?

You just use them. A loop is not like a function where the variable are local to the function.

 

What's your problem?

when i echo the variable $name out side the loop it says "Notice: Undefined variable name" and when i echo it inside the loop it works fine

Figured it out using an array.. works fine now

[Samsam]

print_r($name)

print_r($email)

 

or to use with echo

 

for($i=0;$i<sizeof($name);$i++) {

echo $name[$i];

}

declare the variables before the loop.

 

$email="";

$name="";

[KevinM1]

declare the variables before the loop.

 

$email="";

$name="";

 

That's actually defining a variable.

 

Declaring a variable: simply writing a variable name to be used later ($var;).

 

Defining a variable: declaring a variable and assigning a value/initializing it in one step ($var = "value"; ).

 

Variables cannot be used unless they contain a value.
