Proper way to declare multiple vars in PHP

Question

I\'ve been coding personal scripts for years in PHP and get used to turn off Error display. I\'m about to release some of these scripts and would like to do it the proper way.

In OOP you can use this approach:

protected $password, $full_name, $email;

For non-OOP you declare them just in code they will be Undefined if you didn't assign any value to them:

$foo; $bar; $baz;

$set_foo =  (isset($foo)) ? $foo : $foo = 'Foo';
echo $set_foo;
